Continuous neighbour discovery approach for improvement of routing performance in WSN

Abstract

Wireless sensor network(WSN) contains a number of sensor nodes distributed in the sensor field. Sensor nodes gather information from the environment, process them and then transmit data to the sink node. To send data from the source node to sink node require efficient routing algorithm. This routing algorithm plays important role in WSN is to finding a reliable path for a data transmission in the network. For all these processing sensors nodes require high energy, but sensor nodes have a limitation on battery power. Therefore the design of routing protocol in WSN is based on minimizing energy consumption and routing overhead. The proposed work implements Opportunistic based neighbor coverage routing. In this hop-by-hop opportunistic routing is done by selecting a forwarding node on the base of the current load on the node, energy, and neighbor coverage information. In this choosing of the reliable node in the path, an establishment is based on load information table. Proposed protocol minimize energy consumption and enhance network performance as compared to existing routing protocol.
