Abstract: The paper designed a Chain-cluster based Hierarchical Clustering Routing Protocol on the base of LEACH and PEGASIS algorithm CHCRP.CHCRP algorithm divided the network into several layers and improved the cluster head selection mechanism of LEACH protocol.In the one-hop competition mechanism cluster heads are distributed evenly.To reduce chain routing latency the cluster heads formed "main chain" and "next chain" in layers for multi-hop communication.The simulation results show that the algorithm can balance energy consumption of communication among cluster heads,extend the life cycle of wireless sensor network and reduces the lag of data transmission.
