Virtual Coordinates Routing Using VCP-M in Wireless Sensor Network

In a short time virtual position based routing has established itself as a potent research area in wireless sensor networks (WSN). Although GPS based routing solution are available but they have the disadvantages of being costly, have limited indoor operation and network unreliability in sensor networks creates significant overhead on geographical routing. Virtual routing protocols provide some remedial measures with desirable trade offs between performances and overhead that occur in the case of geographical routing. In this paper an improved localization method called VCP-M is proposed followed by a greedy routing method. A good localization method in wireless sensor network reduces overhead on nodes in terms of receiving and sending packets. A node in WSN has limited amount of energy, so proper utilization of energy is of utmost importance. The proposed localization method in the protocol reduces the number of packets generated in the network significantly. This results in less overhead on the nodes to process the packet. So energy of the nodes are utilized without much wastage.
