Abstract
Uneven clustering is one of the feasible methods for energy hole avoidance and lifetime prolonging in a wireless sensor network. Usually all weight in clustering and routing, such as residual energy of a sensor, distance between different nodes, and so on, are invariable all the time. In fact, with the running of the network, the relative importance of all factors makes the change. A weight-adjustment based uneven-clustering (WABUC) protocol, is proposed for energy hole avoidance in wireless sensor networks. The characteristics of the paper are to adjust the weight of residual energy of a sensor, distance between different nodes to avoid energy hole. Simulation results show that this approach is better that others in terms of energy hole avoidance and achieves an obvious improvement on the network lifetime.
