Abstract: In wireless sensor networks multi-hop routing is often used because of the limited transmission range of sensor nodes. Opportunistic Routing is a multi-hop routing for wireless sensor networks. In this routing, the neighbors of sender node overhear the transmission and f“`orm multiple hops from source to the destination for transfer of information. The neighbor nodes set participating in the routing are included in the forwarder list in the order of priority. The node with highest priority is allowed to forward the packet it hears. A new protocol by Energy Efficient Selective Opportunistic Routing (EESOR), is implemented in this paper that reduces the size of forwarder list by applying a condition that the forwarding node is nearer to the destination. The path followed by acknowledgment packet follows opportunistic routing, assuring reliability of transmission and energy balancing. NS2 is the simulator used to implement the algorithm and results of simulation show that proposed EESOR protocol performs better than existing Energy Efficient Opportunistic Routing (EEOR) protocol with respect to parameters End-to-End Delay, Throughput, Routing Overhead and Network Lifetime.
