摘　　要：拓扑控制是无线传感器网络中的常见控制方法。从节点度的角度进行拓扑构造设计,对网络性能如连通性、覆盖性等有显著影响。基于此,重点研究典型算法LMA,通过OMNeT4.0++平台,设计并调节每个节点的发射功率,从而优化节点之间的拓扑连接,延长网络的生命周期。仿真实验表明:LMA算法能够自适应地实现网络节点度的调节,在满足网络连通的前提下降低全网的能耗,该对数极坐标变换LMA算法具有一定的推广应用价值。Topology control is a common control method in wireless sensor networks.The topology structure design from the angle of node degree has significant influence on the network performance such as connectivity and coverage.Based on it,the typical algorithm LMA is mainly studied.Through OMNeT4.0++platform,the transmission power of each node is designed and adjusted so as to optimize the topological connection between nodes and extend the life cycle of the network.Simulation results show that the LMA algorithm can adaptively adjust the degree of network nodes and reduce the energy consumption of the whole network under the premise of satisfying the connectivity of the network.The LMA algorithm of log-polar coordinate transformation has a certain value of promotion and application.
