Novel clustering protocol based on dynamic optimal number of clusters for wireless sensor network
一种新的基于动态最优簇数目的WSN分簇协议

To improve the performance of Low Energy Adaptive Clustering Hierarchy (LEACH), a novel clustering protocol called Dynamic Optimal Number of Clusters (DONC) was proposed. In the set-up phase, it can determine the optimal number of clusters according to the remaining number of nodes rather than a fixed number. Furthermore, the remaining energy and the geographical position of nodes were fully considered in cluster-head selection; in the steady-state phase, a modified multi-hop algorithm between cluster-heads was adopted. Simulation shows that the new protocol can guarantee the number of clusters is always in optimal state, and ensure the cluster-heads distributed evenly in the network and effectively prolong the system lifetime.
