摘要： 在传感器节点受到能量严重制约的情况下，如何合理地选择自适应拓扑变化的路由协议，有效地控制节点传输半径来提高系统的整体性能，成为当前无线传感器网络研究领域的热点问题之一。在基于RSSI测距技术的基础上，引入了3种传输距离控制策略，同时结合时延和能耗这两个指标，对3种传输策略进行了比较。仿真结果表明，动态选择传输半径可显著提高网络的整体性能，延长网络的生命周期，并减少节点能耗和传输时延。
关键词: 无线传感器网络，路由，传输距离控制，传输半径
Abstract: In the case of the restrictions of energy on wireless sensor nodes,how to reasonable routing protocol of adaptive topology change and control research fields.Based on RSSI ranging technology,this novel introduced and compared three transmission distance control strategies,which utilizes time-delay and energy-comsumption as the reference index.Simulation results show that,choosing transmission radius dynamically can obviously improve the whole performance of the system,prolong the lifetime of the network and decrease the energy consumption and time delay of the sensor nodes.
Key words: Wireless sensor networks,Routing,Transmission distance controlling,Transmission radius
