Resource Optimization Using Software Defined Networking for Smart Grid Wireless Sensor Network

There has been a decade of extensive research on application specific wireless sensor networks (WSNs). The recent development in communication network technologies makes it practical to realize a new WSN paradigm or controlling the control plane with the new group of by software defined networking (SDN) based on Open Flow. The Open Flow technology which is known for standardization and compatibility network Virtualization has brought a lot of innovative solutions in the field of research. In WSNs, sensor node are complex, highly dense and hence difficult to move. Network topology fast changes with time by using routing protocol, network topology, load balancing, power optimization, security and other factors. In this paper, the concept of SDN in WNS is introduced where Open Flow is the controller part of network.
