基于最大生存周期的无线传感器网络能量模型研究

Study the Energy Model for Wireless Sensor Networks Based on Maximum Survive Period

在分析了无线传感器网络的应用和特性的基础上,从节点能量计算模型、节点的能量消耗模型和状态转换模型3个方面论述了无线传感器网络的系统能量模型,通过引入Flag标志和长期睡眠状态机制来防止网络中的某些节点因为过早耗尽能量而死亡,从而实现无线传感器络中节点的能量均衡和网络生存周期的最大化,对无线传感器网络的应用和研究有着深远的意义。

Based on analyzing the application and characterization of wireless sensor networks, statement the system energy model of wireless sensor networks from three aspects of the node energy calculate model, node＇s energy consume model and state and state transition. In order to prevent some node die early for energy - comsumed, we take the sign of flag and long - term sleep to implementation the energy balancing and the maximum survive period. It has important significance on the application and study for wireless sensor networks.
