摘要
针对无线传感网络中拓扑控制方面存在的问题,提出了一种基于移动服务计算的传感网络模型。通过对路由空洞、孤立节点和睡眠调度三个主要问题的分析,建立了相应的拓扑控制方法。仿真研究表明该方法能有效的减少节点能耗,网络的通信负载得以显著减轻,从而延长了无线传感器网络的生命期。
In order to solve topology control problems in wireless sensor networks （ V/S N）, a mobile-service based network model was proposed in this paper. Through the analysis of typical problems of hole-avoiding routing, isolated node and sleep scheduling, a topology control approach was presented on the basis of m o b ￡e-service computing. Simulation results show that, the approach can effectively reduce energy consumption of network nodes, and significantly reduce network traffic load, thereby prolong the lifetime of wireless sensor networks.
