Xiao Chao Dang, Zhan Jun Hao · Applied Mechanics and Materials · 2012
Aiming at the energy heterogeneous wireless sensor network, this paper proposes This paper proposes the remaining energy prediction model based on energy matrix and a novel clustering algorithm .The Kalman filtering algorithm was introduced into the model, in which a node , according to energy prediction mechanism , independently makes it s decision to compete for becoming a master cluster head in order to improve energy efficiency. Simulation results show that the algorithm can balance the network energy consumption, improve the utilization efficiency of node energy and prolong the network lifetime.
