Week 2 [08-14.04.2019] Optimization of smart homes


Hello everyone,

I would like to present you an article about smart homes:

Smart home technology uses devices connected to the Internet of things (IoT) to automate and monitor in-home systems. This technology allows users to control and monitor their connected home devices from smart home apps, smartphones, or other network devices. Users can remotely control connected home systems whether they are home or away. It allows for more efficient energy and electric usage as well as ensuring that home is secure.

Presented paper introduces an approach that considerably lowers the wireless sensor node power consumption, the amount of transmitted sensor events on location and thereby saves the costly wireless transportation of these events which in turn reduces the interference level.

The usage of complex smart object nodes with embedded Artificial Intelligence allowed to achieve the intended goals. It is surprising that the overall sensor node power consumption has been reduced by 99 percent.

Questions are:

  1. Do you have a smart home? Does a smart home affect the privacy of people living in it?
  2. Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?
  3. What do you think about the effectiveness of the results in presented article? Has the optimization of the assumed elements been really done or only the existing solution has been complicated?

  1. 1. Do you have a smart home? Does a smart home affect the privacy of people living in it?

    Personally, I do not have a smart home, I think it is difficult to find many such houses or flats in Poland, especially on the rental market.

    I know, however, a few people who have decided on such a solution and I know how long and hard way they have gone that their apartment could be used. As it turns out on the Polish market, there are few companies offering such services, especially for demanding clients who would really like to have a system that works very well and at a comprehensive level. They do not have privacy problems, simply with the providers of such services.

    2. Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?

    It all depends on users. I have the impression that in Poland users of such solutions are people who do not spend much time in their home at all. It's more of a gadget for them than any necessity and great convenience.

    As for the interface, I think that as with any other IT solution you need to apply certain usability patterns so that the client can easily handle the program. I do not know the subject well enough to rate the network solutions.

    3. What do you think about the effectiveness of the results in presented article? Has the optimization of the assumed elements been really done or only the existing solution has been complicated?

    Personally, I have mixed feelings, especially because of health issues and the fact that we should not be exposed to wireless Internet to such a large extent. This solution seems to be logical, but I have never worked on similar products and I do not know much about networks.

    1. Thank you for your comment. I agree with you that smart homes are expensive and that it is not so popular among available flats. Basically, smart are houses – not flats. Of course, we don’t know the impact of wireless waves on our health so it is better to prevent in this case and try to limit them in our everyday environment.

  2. 1. Do you have a smart home? Does a smart home affect the privacy of people living in it?

    Unfortunately, I don't have a smart home. I believe that this is just the beginning of this type of solutions in the world, not only in Poland. House intelligentsia costs a lot and probably at the moment few people can afford such solutions. I don't even know people who would build or modernize their old home to this level.

    2. Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?

    They are extremely important. The impact on the natural environment in which we want to live for as long as possible now has every source of energy. Even solar panels or wind farms must be disposed of on a beautiful day. Then we will have a problem with these ecological energy sources. So in my opinion, reducing energy consumption is very important.

    We also need to overcome the level of interference. New devices telephones, modems, induction cookers generate so many distortions that they surround us from everywhere. Physicians show a harmful effect of disturbances on the body, scientists refute - the war continues.

    3. What do you think about the effectiveness of the results in presented article? Has the optimization of the assumed elements been really done or only the existing solution has been complicated?

    As I wrote earlier, we should limit the amount of magnetic field that surrounds us. Thus, the amount of networks surrounding the network, especially Wi-Fi, should be limited by us. Did the authors of the article manage to limit the number of "disturbances" or not, it is difficult to judge. I think I would have to get acquainted with the greater amount of research gathered in the field, because matter is not well known to me.

    1. Yes, you’re right. This technology isn’t so popular because it is expensive. However, I personally know a few such houses where smart technologies are used, such as: CCTV monitoring, remote management of central heating or lighting. Their owners are not millionaires - they just thought about it during the building of the house. Smart homes are becoming more and more popular. There are also many companies on the market that offer such services.

  3. 1. Do you have a smart home? Does a smart home affect the privacy of people living in it?

    I do not have a smart home. I think, however, that with time more and more devices will offer smart options and will replace traditional solutions. I can already see that there are a lot of solutions controlling light switches and power sockets. The safety of such solutions raises a little bit of my doubts, already now often various types of devices have unsolved vulnerabilities, with the development of this technology there will be more and more of them. This will be a threat to our privacy.

    2. Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?

    As I already mentioned, there will be more and more of these devices and most of them will work wirelessly. So I think that it is important to discuss this topic and look for solutions that will minimize the interference but also affect our environment as little as possible.

    3. What do you think about the effectiveness of the results in presented article? Has the optimization of the assumed elements been really done or only the existing solution has been complicated?

    The results presented in the article look promising. The question remains how it will work in the real application and whether the integration of the cloud does not constitute another threat to the security of the entire solution. But of course I think that the topic is worth a deeper analysis.

    1. I agree with you that every new technology deployed in our everyday life is a new threat to our privacy. The author of the presented article proposes the usage of another AI system to control wireless sensor nodes - it is a new threat and a new source of problems.

  4. Do you have a smart home? Does a smart home affect the privacy of people living in it?

    I have some elements of the smart home appliances at my apartment. We are using Google Assistant as its primary controller, which is responsible for lights and an air purifier control. Yes, it has an impact on the privacy of the people living in it because you need to agree that it's listening to your voice whole time.

    Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?

    I like the "better safe than sorry" approach. Because right now even light bulb has a wifi module, I believe that in the future every single electronic item would have it's own data to share with others. It would be good to introduce some low-level mechanisms that would separate the wheat from the chaff, so there would be lower network bandwidth and power consumption.

    What do you think about the effectiveness of the results in presented article? Has the optimization of the assumed elements been really done or only the existing solution has been complicated?

    If I well understand the presented approach, the author would like to introduce a middleware that aggregates the data from sensors and decides whether to propagate it or make some other action. I think that sensors itself should be prepared in the "smart" way, additional devices/filters are unnecessary overhead.

    1. Thank you - great idea! The usage of smart sensors would certainly help but there must be some central element that will synchronize them and manage their work. I am also afraid that in this situation it will be difficult to achieve this goal without the centralization of management which, unfortunately, also consumes electricity…

  5. 1. Do you have a smart home? Does a smart home affect the privacy of people living in it?

    "Smart" it too much to say ;)
    I have Raspberry Pi with my own program which control temperature inside my home, checking who comes to home (using camera streming and easy face recognition algorithm implementation) and send me messages if something is wrong (I can define my own rules). Moreover I use microcontroler STM32 series to checking my network traffic (active firewall). To be honest that's something new so I can't say anything about effectiveness of that solution.
    Of course. As I said I checking who comes to my home and about what time. I got frame with every new guest detected on camera (on many frames of course,not only one). But everyone know about that solution and to be honest...they want it also. It's nothing wrong to know who comes to YOUR house ;)

    2. Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?

    Of course it is important! People live in flats so all neighbours have they own private LAN networks. That's problem especially when then use the same channel and the same frequency. Then your network is just poor.
    I know that everyone want to have the best possible signal in his flat/house but easy change (channel change) could makes "miracles" and we don't have to suppress ours signals. Other thing is frequency...we can't do anything with that. Lucky for us the new frequency 5GHz don't generate so much noise as 2,4GHz (e.g. in this frequency working microwaves).

    3. What do you think about the effectiveness of the results in presented article? Has the optimization of the assumed elements been really done or only the existing solution has been complicated?

    ...I'm skeptical. To be honest that result are very impressive. I don't think that in real life we could have similar (I don't believe that the same) results.

    1. Your house is your property and only you decide who can enter it. However, I was asking about privacy of people who are living in your home. Raspberry Pi is well known for me (on this platform I created monitoring for public transport as my BSc thesis) and there are a few exploits for these devices (if you are using Raspbian OS) that allow to capture data. In my opinion it may case some danger when it comes to the privacy of the household.

    2. Luckilly for me I use ubuntu on my Raspberry so it's not so easy ;)
      Hmmm...what can I say about household privacy? The camera is using only to recognise face who cames and exit. I don't use camera in the other parts of house.

      Delete
    3. Good for you and your household! ;) After all, you should be careful because both Ubuntu and Raspbian use the same Debian kernel.

  6. 1. Do you have a smart home? Does a smart home affect the privacy of people living in it?
    I guess my home is pretty smart. Have more smart wifi devices connected than computers and mobile phones. We don't care about perceived privacy loss, as the data is processed by AI learning things rather than other humans.

    2. Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?
    In case of smart appliances, network load is neglible, unless device is battery-powered (network traffic causes energy drain) or device needs to talk directly to some cloud server. On the other hand, interference is quite important I think, as radio frequencies are limited resource. Both interference between devices of the same network and between overlapping networks.

    3. What do you think about the effectiveness of the results in presented article? Has the optimization of the assumed elements been really done or only the existing solution has been complicated?
    The problem I see is that the optimization takes away communication at regular intervals, which acts as a heart beat. I can't be sure if device is not communicating data because bayesian filter cut it out or because it's battery is dead. On the other hand, there are sensors that can safely batch series of fast changes of output values and send it in one go, cheaper w.r.t. energy. Example would be seismic sensor, but that is not something we often have in smart home setups.

    1. In my opinion, you raised a very interesting topic – a human as the weakest link in privacy ensuring. It is usually a man who is either a reason or a victim of data leakage. The problem of running out of batteries can be solved by a low battery notification. This is an old and proven method which many devices use today.

  7. 1. Do you have a smart home? Does a smart home affect the privacy of people living in it?

    Unfortunately, I do not have a smart home but I really would like to live in a smart home. Nowadays, Internet of Thing is more available for people and it makes their life easier. The intelligent house is expensive so not everybody can afford it. The parents of my best friend have a smart home and they use for example a smartphone to control and monitor their home. If I lived in a house I would like to make a smart home. You asked about the privacy of people living in this kind of house so I think that the data about us are collected all the time. I suppose that a smart home does not affect our privacy.


    2. Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?

    Yes, I agree with the topic of saving network load or reducing the interference level are important nowadays. The mentioned issues have the impact on the natural environment. The resources may be depleted one day so I think we should consume them more deliberately. Minimizing of the energy resources allows to obtain the less influence on the natural environment. The interference is very important for health of people it can cause the diseases and the irreversible effects on health. However, there are not many users of smart homes in Poland but I suppose that their number is growing.


    3. What do you think about the effectiveness of the results in presented article? Has the optimization of the assumed elements been really done or only the existing solution has been complicated?

    The results which are presented in the article seem to be promising. I am not an expert in this field but I think that the presented solution may allow to increase the effectiveness of controlling and monitoring a smart house. The solution based on artificial intelligence could be the new approach in such systems.

    1. I agree that the presented solution is innovative and easy to implement but with this energy saving it is not so great. Yes, we save batteries in the wireless sensors, but unfortunately the system with AI also needs power... The only added value - which I see in this solution - is to reduce the frequency of battery replacement in those sensors.

  8. Do you have a smart home? Does a smart home affect the privacy of people living in it?
    No I do not have smart home. Smart home devices affect people privacy. Smart speakers record residents’ conversations. Thermostats equipped with motion sensors track the whereabouts of each household member, and when they leave the house. Refrigerators remember grocery lists and spending habits. When residents invite smart technology into their homes, they are gambling with their privacy.

    Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?
    As more people and devices are connected to the network there is a need to save a network load. I am not an expert in this field but I think tech companies are already working on how to iprove this.
    What do you think about the effectiveness of the results in presented article? Has the optimization of the assumed elements been really done or only the existing solution has been complicated?
    I am not an expert in this filed either. This technology looks promising, with 5G technology and connected network it will be one of the most distruptive technology.

    1. I am curious if indeed the load on the network is so important in today's world of optical fibers and efficient network devices... Most probably it wouldn’t be felt at all if we used good access points, switches or routers. Unfortunately, we have such a tendency on the market that Internet service providers are pushing us with poor edge devices.

  9. Do you have a smart home? Does a smart home affect the privacy of people living in it?

    I have remote-controlled heating. This allows me to freely set the desired room temperature with an accuracy of 0.5 degrees. I have written a program which calculates the heating curve depending on the wind, outside temperature and humidity. Thanks to this and the use of the calendar I have the perfect tempeature just when I come home. In my application it is possible to display messages, for example about possible errors in the operation of the heating system, in Polish. The software is not only convenient but also, thanks to the touch screen and intuitive navigation, very easy to use. In addition, access to the application is password protected, so only people who know it can change the settings of the heating system. An intelligent home offers many advantages, but at the same time it is a serious challenge for network security and privacy of users' data. Dealing with these obstacles will require a variety of security techniques, including authentication of network connections, use of private network users to communicate with connected devices, anti-virus software and protection against attacks on cloud applications.

    Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why

    Saving energy in an intelligent home should not force the household members to sacrifice their comfort or freedom just to achieve lower energy bills. Intelligent energy saving does not require changes in habits, lifestyle or additional household duties.
    If only the system can control lighting, thermostats, and other power-eating devices, it can save energy with a really high efficiency.
    For example: You will never leave the light on again, the playing music player or the TV on. Sunlight can heat rooms very quickly, causing unnecessary temperature rises in an air-conditioned room. Automated blinds can cover selected windows at certain times of the day. You can also use sensors instead of referring to selected times of the day to determine when the level of sunlight requires you to cover your windows. The same is what I want to do at home.

    What do you think about the effectiveness of the results in presented article? Has the optimization of the assumed elements been really done or only the existing solution has been complicated?

    However, such a system is very complicated because. To lay a wired system, an electrician will use many kilometres of cables. For example, each light source operates a separate white cable and runs to the switchgear. The control cable runs from each connector. In the system there are two switchgears with separate controllers with overvoltage protection in the network, some circuits must be doubled in case of failure of any controller. And, of course, a generator is required. But the biggest profits can be obtained, however, by controlling the heating.

    2. It's great that you have such solutions in your house. To avoid the usage of kilometers of cables wireless sensors are used. Of course, this involves all hazards that wireless technology brings with it and additional power supply. In the case of a new home, it can be designed during construction. In the case of adding smart functionality, however, it is convenient to use battery power.

    I don’t have a smart home. I think it depends of devices you used in home. If you use system to controling temperature in home then probpably not but if you have installed monitoring system for security with camera device s then i think it could affect privacy.

    2. Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?
    I think it's vey important but i don’t have expert knowledge about this topic. Nowdays many device generate interferences that could have affect on our life. We need to reduce the interferences of them. When we reduce energy consuption we could save money and help natuaral environment.

    3. What do you think about the effectiveness of the results in presented article? Has the optimization of the assumed elements been really done or only the existing solution has been complicated?

    The results are very good but we need to check it in real environment with many sensors. In the article was presented a simulation. We need to think about advanteges and disadventeges of this solution. The training of AI could be a disadventeges becouse it costs time. An advanteges is reducing Energy costs and interference level. I think the optimization is realy done becouse author reduce routed sensor events form 1795 to only 7.

    1. Thank you – very good analysis of the results. Optimization always depends on many factors. The most important thing is to choose what you want to optimize: energy consumption, performance or system structure. Usually, it is impossible to combine these three dimensions, in particular at a satisfactory level.

  11. 1. I do not have a smart home and I do not think I would ever want to have it. Despite many safeguards of such systems, I still think that it would be easy to break into such a house, for example, cutting off electricity or disturbing the magnetic field at sensors. In addition, thanks to such devices it is easy to spy on our daily schedule, whether we are at home or not, in which room we usually stay, etc.

    2. Of course. Currently, everyone uses many devices working via wi-fi. It causes that a lot of signals and frequencies pass through our house. The ability to control them would allow for more efficient access to the Internet without having to sit at the router itself. Which is a big problem for me, because I have about 10 other networks through my apartment that disrupt my wi-fi signal and the internet at the other end of the house works as if it was not there and the operator can not do anything about it.

    3. The presented results are interesting, although such a large reduction seems to be a simulation calculation rather than a real result. On the other hand, however, it has been seen more than once that the use of AI improves the efficiency of various systems. I do not have much knowledge in this field, but it seems to me that this method can potentially be of great use.

    1. I agree with you that the implementation of any new technology brings with it the risk of breaking-in, data capturing or even taking over the device. On the other hand, we can’t avoid new technologies because of this. It would result in the fact that none of us would use smartphones nowadays. It is usually so that taking a step forward involves taking some risk.

  12. Hi Damian,
    many thanks for the topic interesting for me :-)
    1. Unfortunately, I haven’t smart home, but I dream to have one. In Polish conditions such equipment and installations seem to be a luxury goods, not available for everybody. It is expensive, but I don’t expect this is a matter of the costs. People in our country simply are not ready to spend ANY money on things they don’t understand.
    Definitely, such smart home does not affect any privacy just because of being smart. This is us who define the rules it works and control the system. We can even achieve more privacy and simultaneously such system may give us more security, warning us when the strangers are close to our house.
    As I mentioned above, smart houses are not popular in Poland for cost and fear reasons, that’s why, for sure, installing such systems we have to exhibit ourselves a bit to the others, so this way we obviously decrease our privacy, but this is a matter of time, when it will be more expected to live in smart home rather to a different one.
    2. Such topics as saving network load or reducing the interference level are now very important, because we are close to energy sources exhaustion. As understanding human beings, very aware of our influence on the environment we live in, we should take care about the quality, the kind and the amount of energy we use in our everyday life. Otherwise blockchain visions will appear in our reality very soon.
    3. In my opinion these are not illusory optimizations and the effectiveness should be estimated or even precisely calculated in the several years perspective, to show the difference between potential old-fashioned approach (what is easy to predict having past data) and the modern one. And this is the reason such smart systems should gain more and more interests, because with the data prepared this way, we’re going to be able to convince all the conservative thinking people. They will not discuss with the exact numbers. So there is a lot of work to do for engineers now.

Your thoughts are very interesting - as always :) I’m not sure if it is possible to convince all the conservative thinking people but well done research will always be an irrefutable argument. Our privacy definitely depends mainly on ourselves but sometimes there are some vulnerabilities or bugs in the system on which we can’t influence.

    First of all, I would like to thank you for a very interesting article. Unfortunately, I don't have a smart home, but I really do hope I'm going to have one at some point in my life. As far as the second part of your question is concerned, whether the house and its equipment affect someone's privacy or not, is a matter of the appliances and systems you have there, so I'm deeply convinced that one may have a smart home and have no problems with privacy breaches whatsoever.


    2. Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?

    I think such topics are very important. Soon, we will reach energy production limits and saving network load, reducing interferences level, reducing power consumption will become really burning subjects. We need to start thinking about our environment and planet, otherwise our children's and grandchildren's future won't be as bright as we might think.

    3. What do you think about the effectiveness of the results in presented article? Has the optimization of the assumed elements been really done or only the existing solution has been complicated?

    1. Yes, the reality will verify the presented simulations. When I was asking about the effectiveness of the results, I meant the actual energy saving in the situation of adding the AI system to the smart structure. It may turn out that we did not save any energy in this way...

  14. 1. Do you have a smart home? Does a smart home affect the privacy of people living in it?
    I do not have a smart home or an apartment. In our country, not many people have chosen this solution. The reason may be primarily costs and a small number of companies specializing in this field. However, I know that in my area there are people who have houses that are in a smart part, for example: a connected central heating furnace, which they can control from anywhere having an internet connection.
    2. Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?
    We currently have a very high demand for electricity. In most household appliances use electricity and its consumption is growing all the time. Every way to save energy is very valuable.
    The second important element for any device operating in the network is the transmission of waves. This involves dealing with certain bands and with a large number of transmitting devices on the same channels, interference and irregularities in the network operation occur. In addition, data sent wirelessly is easy to capture and then break into such a network.
    3. What do you think about the effectiveness of the results in presented article? Has the optimization of the assumed elements been really done or only the existing solution has been complicated?
    The results presented by the author are somewhat surprising. If it is such a good solution, why is it not used on a large scale (or maybe I did not meet with it on the local market)? On the other hand, the author himself writes that one should still train artificial intelligence responsible for handling particular nodes. I believe that an individual approach to any such home should be applied because of the owners who use smart homes in a variety of ways.

    1. Presented paper is quite new – it was published on the Arxiv website this month. Perhaps that’s why this solution is not yet widely used. You are right that an individual approach would be the best in this case. At first it probably will be like that but with time, when smart homes become more popular, general solutions will appear with the possibility of some modifications for users.

    Unfortunatelly, no. But I don't want to have a proprietary and overpriced solution, I would like smart home components to be cheap, commoditized and mostly open. Like PCs which you can assemble yourself, bringing components from different vendors and building something of your own, thanks to open standards.

    2. Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?

    No and yes. We're awash with bandwith: optic fibre, 5G mobile broadband, 10G ethernet, new standards of WiFi: all this is far more then simple IoT systems need to function. N

    Nice test question, but even after scanning through the article I can't make out what it's all about. The natural thing to do is to limit the sampling of the sensors, but instead of an arbitrary limitation, we use some 'magic' (read: AI). They sure made it (look?) complicated. The main idea is transmitting 'events' in lieu of raw state at some sampling rate. This an give frequent updates when something is 'going on', and relatively rare otherwise.

    1. You got me! The last question was asked in order to involve bloggers in an in-depth analysis of the presented article. I agree that this solution looks complicated. On the other hand, the real measurements are missing. In addition, the author does not estimate the energy consumption of the AI system. I also agree with you that in the era of optic fibers the network load is of little importance.

  16. 1. Do you have a smart home? Does a smart home affect the privacy of people living in it?

    No, I don’t have a smart home. In my opinion, the technology is not at its peak yet, and I’m waiting for a better moment to start going smart
    In my opinion people might still feel that their privacy is a little violated, but I trust that the system become more transparent and easier to understand so the privacy issue won’t be a problem.

    2. Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?

    I believe that digital evolution requires some time to become the most efficient version of itself and reducing interference is one of the steps in this process. Saving network, thou is not as important as maximizing it’s abilities.

    The results look very promising, but I think they might be hard to achieve at this moment in real life situation. I am not an expert in that field, but I’m am looking forward to it.

    1. Thank you for your comment. I agree that it’s not a key moment for smart homes. Mainly because of prices. I’m also waiting for a better time for this technology. Good note about network load - I agree.

    No, I don't have a smart home. Yes I think that smart home affect the privacy of a people inside especially if it is connected to wifi. Then even with the best security solutions you never know if it not broken and if someone do not watching you or listening to what you say.

    2. Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?
    Yes I think that in terms oof smart home it is important. If you have a lot of devices and they have to work constantly to make yourr home smart the network load should be also managed in a smart wat. Reduced interfaces makes devices easier to use and in fact you can get or do what you want faster.

    I think that the results are quite good but I am not an expert in this field. The article seems quite old, the newst citation is from 2013 so probably there are better solutions now.

    1. Indeed, the citations are quite old, although the article itself was published this month. I agree that the proposed solution is trivial but I have not met anyone dealing with this topic. In general, the technology of smart homes is not new any more but time passes quickly...

  18. I don't have a smart home, but I think that lighting system adjusting its brightness automatically would be a really cool thing to have. Also controlling various devices with voice commands could be very convenient. As for privacy, it definitely should be an important issue, especially if we talk about devices that have a camera or microphone or collect our personal data of any source. It's not strictly related, but I remember a case when a bluetooth toy with a camera could be easily hacked to retrieve a video stream from it.

    I'm not sure. From the user perspective I don't experience any problems when using many devices connected to the same network. I don't have any intuition in this regard.

    The results presented in the article indeed look quite suspicious, but maybe it's because the baseline was really weak? I don't have any experience in this field so I can't really say if improvements of an order of magnitude or few is normal or not in this case.

    1. Yes, I presented an article about the security and privacy of smart toys for children. Taking control of IoT toys which have built-in microphones, cameras or can be remotely moved also pose a threat to our privacy.

  19. Do you have a smart home? Does a smart home affect the privacy of people living in it?
    In my new apartment I have air condition, lights and electrical sockets connected to my smartphone plus normal smart things like washing machine or vacuum cleaner, but I do not have Alexa or something like it yet. It can affect privacy, especially if you are buing cheap staff from China, because you will never be sure if it will not send data not only to you phone and how they will use this data.
    Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?
    I think it moderately important. Of course I don't want to have not efficient comunication protocols, but I think we are learning quite fast how to speed up communication and analysis of this data and I think more data is almost always better than less data. In case of inference I totally agree, even now in flat it is sometimes really annoying when your wifi is not working well, because of routers of your neighbourse.

    If this solutions will work in real life, not only in laboratory and simulations then I am a big fun. At first glance it looks quite surprising, but it is not firs area where good idea and AI can make a difference, so I hope it will proof to be usefull and implemented in future.

    1. Indeed, the quality of the devices that were used is important in terms of privacy. In this situation it is always possible to check where and what data is sent. With control over network traffic you can analyze this problem. Unfortunately, you need time, knowledge and skills to do this.

  20. Do you have a smart home? Does a smart home affect the privacy of people living in it? 
Unfortunately I don’t have a smart home…;) I think that it isn’t unsafe when only you and other residents have access to sensors and data coming from them. In my opinion it doesn’t affect privacy of people living in such houses. What is more, there is also the possibility of system, which will work without the connection to the Internet - based on AI technology. In that case any risk of violating the privacy will be minimal.


    Do you agree that such topics as saving network load or reducing the interference level are important nowadays? Why?
    
Yes, of course. I think that saving resources in any possible way is very important and should be a good topic to explore, especially if - in addition - it allows you to reduce your house bills;)

I’m waiting for results in real life, but like it was said in the article – power consumption for AI systems and expense of such systems would be similar to systems without AI. I think it is worth to try such system in real life. If not for saving resources, than even for resident’s comfort.

    1. An interesting idea with a system that does not have access to the Internet. I am afraid that by choosing this way we deprive the user of many functionalities offered by a smart home. I agree with you that the implementation of the AI system will increase the standard of the usage of a smart home.
