事件驱动型无线传感器网络能量监测机制研究
摘要
在分析现有无线传感器网络能量监测机制的基础上
针对事件驱动型无线传感器网络
提出EDEMM机制。该机制采用成簇结构
簇成员周期性地监测自身剩余能量
当且仅当能量消耗的幅度较大时才向簇头节点汇报
簇头对簇成员发来的消息进行处理
当簇头融合后的能量超过一定幅度时向汇聚节点汇报。仿真结果表明:EDEMM机制降低了能量消息包的数量
有效地降低了能耗
可以延长网络的使用寿命。
Abstract
Based on the analysis of energy monitoring mechanisms for wireless sensor networks
a cluster-based mechanism EDEMM is proposes.Cluster member monitors its residual energy
and reports to cluster head when its energy consumption is over a certain amount.Cluster head deals with messages from cluster members
and reports to sink when energy aggregated by head is over a certain amount.Simulation result shows that EDEMM reduces the number of energy message packets and energy consumption so as to stretch WSNs’ life span.
