Abstract: Aiming at the energy heterogeneous wireless sensor network, this paper proposes a clustering algorithm. This algorithm adopts cluster head competition parameter based on the condition of node’s resident energy distributing. It decreases energy consumption for communication in the process of clustering and realizes unifrom distribution of cluster head. Resident energy of cluster head and the energy consumption of its base station are considered synthetically between clusters to select the appropriate next-hop route node. Simulation results show that the algorithm can balance the network energy consumption, improve the utilization efficiency of node energy and prolong the network lifetime.
