摘要:
能量是无线传感器网络中的重要资源。为了充分利用区域内无线传感器的能量,对无线传感器的能耗进行建模,提出了能量窗口的概念,在能量窗口的基础上,设计了一种无线传感器网络能量均衡监测方法。构建执行任务的等效节点集合,从集合中依概率选择执行任务的节点,将任务执行的能耗分散在众多节点之间,实现能量消耗的均衡化。构建任务分配树,进行任务的分配和执行,简化操作。根据无线传感器的执行特性,将区域中的节点进行聚类处理,降低处理问题的复杂度,提高算法的可靠性。仿真实验结果显示,无线传感器网络中相同时间里文中算法的节点死亡数要比LEACH算法少,节点存活数量要比LEACH算法多,表明文中算法有效地延长了网络生成有效期。
Abstract:
Energy is an important resource in wireless sensor networks. In order to make full use of the energy of wireless sensor in the region,the energy consumption of wireless sensor is modeled,and the concept of energy window is proposed. Based on the energy window,we design an energy balance monitoring method of wireless sensor network. A set of equivalent nodes is constructed to perform the task. The nodes performing the task are selected according to the probability from the set,and the energy consumption of task execution is dispersed among many nodes to realize the equalization of energy consumption. The task assignment tree is constructed to assign and execute tasks and simplify operations. According to the execution characteristics of wireless sensor,the nodes in the region are clustered to reduce the complexity of the processing and improve the reliability of the algorithm. The simulation shows that the proposed algorithm has fewer node deaths than LEACH algorithm and more node survival than LEACH algorithm,which indicates that it effectively extends the validity period of network generation.
