anism of routing protocols has been carried out and their advantages and disadvantage have also been summarized, based on which an excellent minimum hopping based routing protocol will be , describing the design background of LHBCRP and introducing the MTE and LHR algorithms. Based on the idea of clustering, we introduce the bined MTE and LHR algorithms into WSN intercluster routing Construction. We proposed a new LeastHopBased Clustering Routing Protocol(LHBCRP). LHBCRP improves threshold function considering the residual energy of nodes. By setting the number of the maximum and minimum of nodes to limit the size of clusters, base station and the cluster heads can be municated with each other by the routing protocols bined the algorithm of MTE and the e
