无线传感器网络中的能量分布

Energy distribution in wireless sensor networks

在线性均匀分布的无线传感器网络中,通过分析网络内各种载荷引起的能量消耗及各类路由算法对网络生命周期的影响,提出了通过改变网络能量分布密度来提高网络生命周期的方法.通过大量实验总结出能量分布的模型,并将该模型扩展到窄带区域内分布的网络.仿真实验结果表明按该密度分布时,网络生命周期将明显增加.

Based on the analysis of energy consumption caused by different forces inside network and the influences of different routing algorithms on the net life-time circle, a method was proposed to extend the net lifetime circle by changing the density distribution of net energy distribution under the circumstances of linear uniform distributed wireless sensor networks. An energy distribution model was concluded, which can be extended to a nan, w strip case. The simulation results show that the life-time circle of network is extended when the energy is distributed as this model.
