| 摘 要： | 传感器网络由大量能量有限的微型传感器节点组成,如何延长网络的生命周期是一个需要解决的重要问题。针对圆环形传感器网络,给出了求解网络生命周期最大化模型,得出了圆环的宽度,并定量规划了每个圆环中节点的数目。模拟结果显示:网络生命周期终止时,网络中的节点几乎达到了能量均衡,从而延长了网络的生命周期。

| Abstract: | Since wireless sensor networks consist of a large number of tiny sensors with limited power supply,it is a important problem that how to prolong sensor network lifetime.A maximizing lifetime model of circular sensor networks is presented to abtain cirque width,and the number of nodes in every cirque is computed quantificationally.Simulation results show that all nodes nearly may attain balanced energy depletion at the end of network lifetime to prolong the lifetime. |
