Time synchronization and cluster algorithm for wireless sensor networks is a hotspot in international research,but a hypothesis is always made that the communication between nodes is no conflict,and the mechanism of avoiding communication conflict is ignored.Based on design the algorithm of time synchronization,a self-organized cluster algorithm is proposed,the design and work process of its is analyzed and discussed.The additional parameters including the remaining energy level of candidates and their degrees are synthetically considered to optimize the process of cluster-head selection.By change cluster-head thus to reduce and balanced energy-usage among the nodes,prolongs the network lifetime efficiently.Simulation results show the validity of the algorithm.
