SMART HOME ENVIRONMENT USING * FUTURE INTERNET ARCHITECTURE

Abstract

Internet of Things (loT) is the term given to sinail computing devices embedded in anything and everything around us which will all be collecting data about their environment. This paradigm allows data collection and analysis at a scale never seen before, and of course fme-grained control of the environment. loT covers every aspect of our life in smart homes, smart cities, smart health care, smart industries, and many more. A thing/object/device in JoT can be a smart object like laptop, smart phone or physical object like book, electronic appliance, etc. which is augmented with embedded sensor nodes or RFID tags. These things communicate among themselves to configure and adjust many parameters without any human intervention. E.g. Air conditioner talks to temperature and humidity sensor, and automatically sets itself to a temperature that is suitable for the user. In order for these things to form a network, they must be uniquely identifiable and must have communication capabilities. By 2020, it is approximated that 50 billion devices will be connected in the JoT network. If we use IPv6 addresses for identifying devices, it will provide only 4.3 billion addresses, since it has 128 bit address space. Therefore, IPv6 fails to solve the identification problem of ToT. The current Internet architecture also suffers from performance issues regarding data delivery, because internet was actually designed to provide communication between d end-hosts. Servers providing the data will have heavy influx of requests and as a result their performance degrades. 1-lowever, now-a-days Internet is mostly being used for information dissemination, e.g. social networks, YouTube; when a user needs to download some song; he types youtube.com in the browser, which takes the request to YouTube server. As a V result server has to satisfy millions of requests per a day. It may be possible that the song is available with some nearby node, so instead of going till server we should be able to fetch the data from which ever system has the requested piece of data. I In future internet paradigms names are used for identification of things, Named Data Networking (NDN) concept is used for efficient data distribution, so both IP address exhaustion problem and performance issues of data servers are resolved. In (NDN) concept a user specifies name of the data that is needed, instead of specifying the location where the data is present. And this data will be first searched among all the nearby nodes for possible C availability, instead of directly going to the server. In current Internet architecture channel between end points is secured before data transmission, where as in future Internet architecture data can be transmitted even in an unsecure channel, since data packet is signed by the data provider before distributing. In this dissertation, we have studied future Internet paradigms in detail. We have developed several smart home applications (such as, automatic light control through user movement detection) using real-time NDN communication. Replacing traditional IP based communication with NDN is a purely non-trivial as well as novel task and was a great feat to achieve. We have further developed the cached data delivery model of NDN where any intermediate node having a piece of data requested by other users, will respond with the matching content. This was achieved by setting up multiple hosts as NDN routers using real-time communication over a distributed NDN environment.
