基于实际无线环境的无线传感器网络拓扑控制算法

Real wireless environment based topology control algorithm for wireless sensor networks

提出了一种无需任何位置信息的面向实际无线环境应用的分布式拓扑控制算法(Minimum transmission power based topology control,MPTC),它基于节点最小发射功率计算节点间是否存在每跳能量消耗都小于其直接通信时的能量消耗的多跳路径来构建网络拓扑,在保持网络连通的前提下,降低了网络的能量消耗。仿真结果表明,该算法构建的拓扑具有能量消耗均衡、鲁棒性好等特点。

This paper proposes a simple distributed topology control algorithm named Minimum I ransmission Power based Topology Control （MPTC）. It computes whether there is a multi-hop path t etween two direct communication nodes with the energy cost across each hop less than that of the wo nodes. MPTC reduces the energy consumption while maintaining the network connectivity without the use of location-based information. A simulation-based comparative analysis is presented. The results show that the proposed MPTC has the advantages such as balanced energy consumption and good robust properties.
