摘要
提出了解决无线传感器网络寿命问题的基础是节点分布策略，在一般的无线传感器网络模型和通讯模型下给出了具体的hmax-η节点数分布模型，从根本上解决了制约无线传感器网络寿命的瓶颈节点问题。仿真结果显示，比起简单的节点随机分布模型，hmax-η节点数分布模型极大地延长了网络寿命。
Distributing strategy of nodes is the prime problem to be resolved for prolonging wireless sensor network lifespan.hmax- η distributing model of nodes is proposed based on generally wireless sensor network model and wireless communication model. Simulation results show that h max -η distributing model of nodes can solve radically the bottleneck nodes problem that restricts wireless sensor network lifespan and prolong network lifespan to the utmost extent.
