The most important factor within the wireless sensor network is to have effective network usage and increasing the lifetime of the individual nodes in order to operate the wireless network more efficiently. Many routing protocols have been developed for this purpose. One of these is the LEACH protocol presented by Wendi Heinzelman, which is especially well known as a simple and efficient clustering based routing protocol. However, because LEACH protocol in an irregular network results in a drop in efficiency of the total data throughput, the stability of the cluster is declined. Therefore, to increase the stability of the cluster head, this paper proposes a stochastic cluster head selection method for improving the LEACH protocol. To this end, it proposes a SH-LEACH(Stochastic Cluster Head Selection Method-LEACH) that it is combined with the HEED and LEACH protocol and the proposed algorithm is verified through the simulation.
