Nowadays, the Internet of things (IOT) is becoming more and more popular.Due to routing protocol easy to extend, hierarchical routing protocol, for example Low Energy Adaptive Clustering Hierarchy (LEACH)，is more widely used.In order to lengthen the life of network as long as possible, an improved rotation mechanism of cluster head based on LEACH is proposed in this paper.The main idea is to minimize the reconstruction of the cluster, and change the cluster head in original cluster.We adopted token here.The simulation experimental results on NS II platform show that the improvement can delay the death time of the first node, which makes the energy consumption of the whole network more average.The proposed improved mechanism is effective.
