摘　　要：无线传感器网络的初始配置最优可以减少传感器网络的拓扑变化和降低网络重置的能量消耗。对初始均匀随机分布的无线传感器网络的连通性进行了研究。运用覆盖理论给出了传感器节点的连通度概率分布模型,并在此模型基础上推导出传感器节点的通信半径与期望连通度概率最大之间的关系。仿真结果表明了结论的正确性。The initial deployment optimal of the wireless sensor network can lessen the network topology change and reduce energy consumption for reconfiguration. The connectivity of the initial uniformly random distributed wireless sensor networks is studied. By coverage theory a sensor node connectivity probability distribution model is presented, on which the relation between the sensor communication radius and the maximal probability of expected connectivity degree is deduced. Simulation results testify the conclusion.
