Adaptive Software Defined Node Deployment for Green Internet of Things

The integration of Internet of Things (IoT) and software defined networks is the most suitable network paradigm for development of smart world. IoT based solutions have been developed for fulfilling the gap between Cyber and physical world. There are many issues for realizing the IoT due to its large scale and heterogeneous network structure. Energy efficient node deployment also called green deployment for IoT is one of the major challenging issue. Hence most of the existing deployment methods for WSNs are not workable for IoT. This paper addresses the challenges of deployment schemes to get an energy efficient IoT networks. It presents a homogeneous grid based deployment strategy and a heterogeneous circle packing based deployment strategy. The performance of both approaches are calculated by simulating different deployment scenarios. The network lifetime and energy consumption are calculated. It is found that the circle packing based deployment approach outperforms the other grid based approach in terms of energy efficiency and well suited for the heterogeneous network.
