无线传感器网络运行状态的实测分析与预警

MEASUREMENT ANALYSIS AND EARLY WARNING ON RUNNING STATUS OF WIRELESS SENSOR NETWORK

无线传感器网络运行稳定性问题是个重要问题,网络运行状态的收集、分析和预警至关重要。从节点活跃度,节点感知数据以及节点能量三个角度对无线传感器网络运行状态进行分类和定义,构建高可测模块对网络状态变化进行日志生成和分析,对异常进行预警,提高了网络的可测性。最后,以节点电压监测为例,在上海市计算技术研究所自组织网络实测平台上做了实测分析。

Running stability of wireless sensor network is an important issue,and the collection,analysis and early warning of the network running status are crucial.Here in the paper we classify and define the running status of wireless sensor network from three points of view：the node active degree,the node sensing data and the node energy.We construct a high measurable module to generate the log of network status changes,to analyse them and to warn the abnormalities in advance,which increases the measurability of the network.At the last section of the paper,taking the node voltage monitoring as instance,we perform an actual measurement analysis on self-organizing network measurement platform at Shanghai Institute of Computing Technology.
