Abstract

Internet of Things (IoT) is considered to be the next revolution in the field of wireless communications. This concept involves mapping of physical world to virtual (cyber) world. It is achieved by interconnecting devices having sensing capabilities using unique addressing scheme and passing their collective information to the IoT cloud. However at present, these devices belonging to different technologies are connected to the Internet using IoT gateways. With the upcoming of a large number of IoT devices connecting to the Internet, there exists a requirement of deploying a large number of IoT gateways in the network which is not cost effective. Therefore, in this paper, we make use of low cost Solution Specific GateWays (SSGWs). As voluminous data is generated by these IoT devices, routing in the IoT network becomes a challenge. In this paper, we propose parallel opportunistic routing in the IoT network using varied kinds of wireless technologies used by SSGWs. The simulation results show that our proposed algorithm performs better in terms of average network throughput and average packet delay when compared to normal routing using single technology.
