摘　　要：针对高密度部署节点的传感器网络会产生能耗高、冗余度大等问题,利用传感器节点,通过调整功率来控制通讯半径的特性来控制节点相对距离,并在理论上给出了网络覆盖度与节点相对距离的关系。最后,提出了基于限定区域内随机唤醒机制的无线传感器网络覆盖控制方法。实验结果表明,该方法在保证覆盖质量的前提下,减少了节点的能耗,有效的延长了网络寿命。The method proposed in this paper aims at solving the problems of high energy consumption and high re-dundancy rate in wireless sensor network and these problems are caused by high-density deployment of sensor nodes. This method can control the relative distance between nodes based on the characteristics that sensor node can control its communication range by adjusting power and then provides the relationship between the network coverage and the relative distance between nodes in theory. Simulation shows that the protocol not only can provide the de-sired quality of coverage （ QoC） , but also reduce network energy consumption and thereby prolongs the network’ s useful lifetime effectively.
