In this paper, we systematically analyze the clustering routing LEACH protocols, and make an in-depth study of how the protocol works. The ECHNL routing algorithm based on the probability of hierarchical cluster head is proposed and the improved algorithm simulation environment is built using NS2 platform. Then we compare the algorithm performance of ECHNL, LEACH and RPUCDH. The results show ECHNL algorithm performs well in optimizing the clusterhead election, balancing energy consumption of the network nodes, and effectively enhancingnetwork lifetime.
