In this paper,a low-power hierarchical wireless sensor network (WSN) topology control algorithm,which is called LPH,is presented.LPH is a multi-level topology control algorithm.In this algorithm,the topology control is divided into two phases: network building and network maintaining.The phase of network building includes three tasks: cluster head election,cluster head and nodes identification,and topology optimization.LPH provides solutions to reduce energy consumption in every phase and every task.LPH also provides a solution to balance the distribution of the cluster head nodes.On the other hand,the algorithm extends the network-level and improves the maintainability of WSN by using combination of the static address and dynamic address.The paper analyzes space complexity,time complexity and energy consumption of LPH.Finally,this paper introduces the simulation of LEACH,PEGASIS and LPH algorithms based on NS2,and analyzes the simulation results.
