基于信息熵的无线传感器网络节点能量的汇报机制
摘要
对无线传感器网络自身状态的监测将对延长网络的寿命起到至关重要的作用
而节点剩余能量是重点监控的属性。基于簇的网络拓扑结构
簇头节点收集其成员节点的剩余能量数据
利用信息熵理论对这些数据预处理
以短消息格式把能量数据发送到监控平台。监控平台反向处理接收到的能量数据
以得到剩余能量的原始数据。实验结果表明:该汇报机制可以有效地减少汇报的数据通信量
也可以基本保证汇报数据的精确度。
Abstract
Condition monitoring of wireless sensor networks plays a crucial role to prolong the network life
and residual energy of node is key monitoring attribute.Cluster header node collect the residual energy data of its members node based on cluster style network topology structure.After processing those data by the information entropy theory
energy data will be sent to monitor platform with short message format.Experimental results show that the report mechanism can effectively reduce reporting data traffic
also can basically guarantee precision of reporting data.
