Load Balancing and Collision Avoidance Using Opportunistic Routing in Wireless Sensor Networks

In this paper modified opportunistic routing (MORR) protocol is propose, which focuses on addressing routing issues for wireless sensor networks (WSNs) for prolonging network lifetime and load balancing by selecting forwarder nodes, which have maximum residual energy so that network lifetime is enhanced. Furthermore, throughout the selection of forwarder node, channel interference is also taken into account to offer consistent communication. Consequently proposed scheme minimizes the chances of collision and packet duplication at the network layer by controlling number of forwarders and transmitters. Simulation results show that our scheme outperforms in term of average number of transmissions per packet, packet delay, energy consumption and residual energy as compared to baseline solution.
