A communication load balanced dynamic wireless sensor network topology management algorithm based on AODV (CLB-AODV)

In this paper, a communication load balanced dynamic topology management algorithm (CLB-AODV) is proposed to extend the wireless sensor network (WSN) lifetime via managing the participation in communication process among all nodes in the network. The idea is that, each time there is a failure in the network topology; the topology is adjusted only on-demand by choosing the best path according to paths weights between source and destination nodes. The path weight reflects the nodes participation in communication process through the lifetime of the nodes. Our algorithm is based on the routing protocol AODV instead of using a separate protocol for dynamic topology control in order to reduce the routing load among nodes. Simulation results show that CLB-AODV can prolong the lifetime of the network, increase the number of alive nodes and reduce the average routing load when compared with some of the most powerful recent algorithms.
