Clustering technique is an effective topology control approach which can improve the scalability and lifetime in wireless sensor networks (WSNs). LEACH is a classical clustering algorithm for low energy scheme, however, it still have some deficiencies. This paper studies LEACH protocol, and put an Improved LEACH protocol which has more reasonable set-up phase. In the cluster heads election phase, we put the energy ratio and competition distance as two elements to join the cluster head election. Simulation results demonstrate that Improved LEACH algorithm has better energy balance and prolong network lifetime.
