Abstract: The cluster-head predication distributed clustering routing protocol(CP-DCRP) was proposed. In the initial stage,BS computes the cluster heads by using the uniform distributed positions, and broadcasts the cluster heads information in the network. After specific-rounds, the cluster heads of the next specifirrounds are computed by the cluster heads,which are the last cluster heads of the last round of the specific-rounds. The cluster heads of the next specifies rounds are computed by executing the cluster-head predication mechanism. All of the computed cluster heads informalion is broadcasted by the last cluster heads in the network. The effect of the specificrounds on the average energy consumption per round of the network was analyzed, and the optimality of the specificrounds as well as the time complexity of implementing the cluster-head predication mechanism was analyzed, the optimum cluster head number was also analyzed. The simulation results show that compared with Leach, CP-DCRP improves the energy consumption balance property of the network and prolongs the network lifetime.
