Analysis & Development of IoT device Module

Abstract

With emerging technology of wireless sensor network, embedded system and cloud computing, the use of Internet of Things (IoT) has been widely popular in applica- tions like home automation. There are already lots of products in a market based on IoT and home automation. But all belong to different manufacturers, platform, OS. So, it is difficult to use and connect different products in one home environment. To remove this problem, this project develops a device module that will work with any manufacturer's product. This module will de ne functional part of any IoT device. Newly developed Iotivity framework is used for this project. Iotivity works on standard defined by open connectivity foundation (OCF). The IoTivity project is hosted by the Linux Foundation, and sponsored by the OCF that is a group of technology companies such as Samsung Electronics and Intel who together will develop standard specifications, promote a set of interoperability guidelines, and provide a certification program to enable the Internet of Things. Any individual or company can contribute to the project, and this may in uence OCF standards indirectly. Iotivity is available on Linux, Tizen, iOS and Windows platforms. It is portable & compatible with many hardware platforms. Iotivity is based on APIs of C & C++ SDK. Iotivity works on client-server based architecture. Communication between client and server takes place through Wi-Fi or Ethernet. Server hosts IoT device and client will perform the task of controlling that device. This project adds functionality on the client part of device. A module is developed, that will define the behavior of client device, response behavior of server device. In this module, discovery process and control process of device from the client side are implemented.
