摘　　要：为平衡能量损耗并用网络生存期最大化,提出1种无线传感器网络(WSNs)中基于能量平衡的节点部署算法。此算法基于距离调整网络部署,也就是根据不同位置的节点能耗调整节点的间距。文中提出能耗最低点并不等于生存期最优。仿真证明基于这种部署策略网络的能耗大大降低,网络生存期比均匀部署策略高160%,同时给出调整距离、网络半径、节点传递范围和节点数量之间的参考关系。Focusing on the balance of the energy consumption and the max of the lifetime for the Wireless Sensor Networks （WSN）, a placement strategy based on distance adjusting is proposed in this paper. It is the first time that the author put forward the total energy consumption lowest is not equal to prolonging the network lifetime. The simulations demonstrate that the energy consumption on the sensor placement strategy is much less than the other strategies and the network lifetime lives 160 % longer than others, and the relations of the adjusted distance, nodes density and network radius are also given in the simulations.
