Energy Efficient Routing of WSN using ProjPSO and V-Leach Protocol

Wireless sensor networks has been one of the important technologies of communication and so many researchers has shown keen interest towards the same technology in last several years. The Wireless Sensor Network (WSN) is a wireless network consists thousands small node with sensing, computing and capabilities of wireless communication. They have been founded very useful to numerous fields like healthcare area, surveillance system, military- emergency, and so forth. As Energy consumption is the key issue, recent advances in wireless sensor networks have led to many new protocols specifically designed for sensor networks where energy awareness is an essential consideration. Energy efficiency is thus a primary issue in maintaining the network. During our research in this paper we have discussed Energy Efficient Routing Protocols for Wireless Sensor Networks. We have researched on various methodology of energy efficient routing in WSN. We have presented Cluster Head Selection and Vice Cluster Head Selection Process using Optimization Problem and proposed a method to select CH and VCH using Modified PSO by considering distance factor and energy of the nodes. Additionally we also proposed addition of well-known MultiHop mechanism for routing.
