Software Defined Networking for Energy Efficient Wireless Sensor Network

Abstract

Wireless sensor networks (WSNs) consist of individual nodes that interact with the environment by sensing and controlling physical parameters such as temperature, pressure and humidity. Considering the energy constraint of nodes in WSNs considerable effort has been taken to design efficient routing protocol in order to prolong the lifetime of WSNs. Clustering is an effective procedure for prolonging the lifetime of the network. Recently, Software Defined Networking (SDN) has been identified as a promising network paradigm for WSNs. In this paper, we present an overview of WSNs as well as SDN. We discuss some recent works that merges SDN with WSNs. Then, we propose our two energy efficient routing protocols to extend wireless sensor network Lifetime. The first contribution we are using clustering method with classical approach. The second contribution we propose a new approach by using SDN paradigm. In this case we are doping part of advanced node by energy in order to play as SDN controller. The simulations result show that our protocol with classical approach outperforms DEEC and SEP. In the other hand the SDN protocol outperform our classical protocol. Finally, we discuss our approach as perspective on how to use and develop communication protocol by using SDN controller.
