基于路径损耗的WSN能量意识拓扑控制算法

Energy-aware Topology Control Algorithm of Wireless Sensor Network Based on Path loss

为延长无线传感器网络(WSN)中节点的生命周期及均衡节点负载,在PLBD算法的基础上提出一种基于路径损耗的能量意识拓扑控制算法PLEATC。该算法使用损耗链路作为度量标准,同时考虑转发节点的剩余能量状况,避免网络中部分节点因负载过重而导致能量提前耗尽。仿真结果表明,用PLEATC算法构建的拓扑能够保证网络的连通性和健壮性,并延长网络寿命。

In order to prolong the life of Wireless Sensor Network（WSN） and balance energy consumption of the node, a Path-loss Based Energy-aware Topology Control（PLEATC） algorithm for WSN is proposed based on PLBD algorithm in this paper. This algorithm not only considers the path-loss as a measure, but also takes the residual energy of the nodes into account in order to void some node running out of energy early. Simulation results show that PLEATC algorithm can ensure the connectivity of the network and has good performance in robustness and balanced energy consumption.
