Balance Routing Protocol for Wireless Sensor Network

In wireless sensor networks where nodes operate on limited battery energy, the efficient utilization of the energy is very important. Operating on limited battery capacity causes the use of energy-efficient routing protocols. The objective of such protocols is to minimize the total amount of energy consumed by the network in forwarding a packet between any pair of nodes. Routing packet on the same path for multihop WSN causes reduction of energy of the sensor nodes which are present in that path. To solve this problem load balanced routing is proposed. In this scheme packets are forwarded on different paths instead of using same path. Considering load balanced routing we derived optimal routing configuration that maximizes network lifetime. The selection of routes is depends on the quality of links that joins two nodes. Therefore, the weightage of links i.e. proportion of utilization is considered. It takes into account the wasted energy due to idle listening, overhearing, and retransmissions. This scheme causes significant improvement in network lifetime. In future we can use this routing scheme for event driven or on demand applications.[5]
