The Internet Of Things

Smart home is one of the most promising applications of the Internet of Things. Although there have been studies about this technology in recent years, the adoption rate of smart homes is still low. One of the largest barriers is technological fragmentation within the smart home ecosystem. Currently, there are many protocols used in a connected home, increasing the confusion of consumers when choosing a product for their house. One possible solution for this fragmentation is to make a gateway to handle the diverse protocols as a central hub in the home. However, this solution brings about another issue for manufacturers: compatibility. Because of the various smart devices on the market, supporting all possible devices in one gateway is also an enormous challenge. In this paper, we propose a software architecture for a gateway in a smart home system to solve the compatibility problem. By creating a mechanism to dynamically download and update a device profile from a server, the gateway can easily handle new devices. Moreover, the proposed gateway also supports unified control over heterogeneous networks. We implemented a prototype to prove the feasibility of the proposed gateway architecture and evaluated its performance from the viewpoint of message execution time over heterogeneous networks, as well as the latency for device profile downloads and updates, and the overhead needed for handling unknown commands.

This chapter shares the experiences in systematic, well-tested, and executed step-by-step procedure for the preparation of the Raspberry Pi single board computer (SBC) for the internet of things (IoT)-enabled applications. This chapter is useful for beginners and professionals working for automation of smart factories with the help of IoT and Cloud. Moreover, interesting data exchange techniques like low power wireless alternatives ZigBee, LORA, BLE, 6LowPAN, SigFox, and multi-queue telemetry transport (MQTT) are also stated. The related IoT preceding and succeeding technologies, like machine-to-machine(M2M), cyber-physical-systems (CPS), web of things (WoT), SCADA are also the part of insights. Various supporting technologies for the success of IoT like commercial and open source IoT cloud platforms, virtual agents(VA), and digital twins are also discussed.
