Cluster heads optimized clustering algorithm for wireless sensor networks and its performance simulations
无线传感器网络簇头优化分簇算法及其性能仿真

Based on the study of LEACH, a clustering hierarchy algorithm named cluster heads optimized algorithm was proposed. The algorithm periodically put all nodes into several temporary clusters distributed evenly in geographical position, and then selected a cluster head in every temporary cluster. While selecting the cluster head, the principle of protecting the lowest energy node should be followed, the selected cluster head should be as close as the lowest energy node. Simulation results show that, compared with LEACH, the algorithm can enable the cluster heads to distribute more evenly in the network, postpone the emergency of the first dead node, and increase the number of data received at the base station.
