Aiming at improving network stability and energy efficiency, an incomplete clustered routing algorithm was proposed to solve problems that fast energy consumption and easy death of nodes and unreasonable cluster-head election and short network stable period in cluster routing protocol of LEACH. Considering remaining energy of nodes in cluster-head election, the proposed algorithm takes advantage of sufficient energy of base station to establish incomplete cluster. With combination of flat routing and cluster routing to transmit data, the algorithm can fairly distribute energy consumption in the entire network. Simulation results show that the networks performance better in terms of stable period by 29.48% and the proportion of stable period in lifetime to 72.53%.
