| 摘 要： | 邻近图的功率控制方法是传感器网络拓扑控制中的一个重要研究方向。对比分析了PRR，RSSI和LQI等几种链路质量衡量指标的优劣，将LQI均值作为邻近图中邻节点的距离度量，构造链路质量邻近图LQPG，并对所构造的链路质量邻近图进行了仿真实验。结果表明，LQPG有着较低的平均节点度，在链路变化情况下，网络有着较低的平均功率，从而有效地延长了网络的生存期。

| Abstract: | The power control method of the proximity graph is one of the most important technologies in topology control of sensor networks.This paper compares and analyzes the characteristics of some link quality index such as PRR,RSSI,LQI,and uses the mean value of link quality indication(LQI) as distance measurement to construct link quality proximity graph(LQPG).The result of simulation proves that LQPG has bounded degree,and under circumstance of variational link,has lower average power and longer network surviva... |
