Abstract
Self-organizing capability enables remote deployment of wireless sensor network to form an ad hoc network having constrained lifetime due to non-replaceable battery source. To enhance lifetime, Sensor network protocols need reconfiguration to re-assign the roles of clusterhead to the high energy nodes for load balancing. We use our approach which is known as `clusterhead-clique' to localize rotation region for local self-configuration. Based on this approach, the node rotates clusterhead position to node in close proximity which is known as `self-rotating' clusterhead. Thus, self-rotating clusterhead switches the role of clusterhead to node in cluster-clique reducing the re-configuration load by containment of self-configuration in close locality. The approach taken in this work suffers from fragmentation/defragmentation. We provide the simulation results of our local self-configuration protocol for Self-Rotation and compared re-clustering [2,14] with respect to energy metrics. The Simulation of our protocol based on Self-Rotation approach achieves 35% energy-efficiency over the existing re-clustering scheme.
