Abstract :
In order to prolong the WSN´s lifetime, a refined protocol named LEACH-H (hybrid cluster head selection LEACH) is proposed in this paper. In the first round of Leach-H, the base-station selects a cluster head set through adopting simulated annealing algorithm; in the followed rounds, the cluster heads will select new cluster heads in their own cluster. This will not only solve the problem that the cluster heads are unevenly distributed in LEACH, but also maintain the characteristics of distribution. The energy consumption of the network is cut down and the live time of WSN is extended in Leach-H.
