无线传感器网络中能量有效的多层分簇算法
Energy-efficiency multi-level clustering algorithm in wireless sensor networks
摘要
Abstract
In view of the load-imbalance problem of nodes in a cluster and energy efficiency in each round for wireless sensor networks, this paper proposed an energy-efficiency multi-level clustering (EEMLC) algorithm.In the first round, base station deployed virtual subarea according to the optimal cluster-heads of every level on the entire networks.In the next rounds, selected cluster-heads of the follow round by cluster-heads of the current round based on the residual energy of nodes in the same subarea.EEMLC effectively ensured that the energy consumption of each round could be balanced.And the same time the proposed algorithm made minimum energy consumption for each round.EEMLC could also efficiently ensure balance of each node in the same subarea.Therefore the EEMLC prolonged the lifetime of WSNs.The simulation experiments demonstrate that the energy consumption of each round in EEMLC has significantly improved compared with the LEACH.The lifetime of WSNs is extended by 11.3％.关键词
