一类三角形网格无线传感器网络监测性能评价方法

针对无线传感器网络结构不统一,缺乏针对性的网络监测性能评价标准这一问题,该文分析了节点失效对一类三角形网格传感器网格监测性能的影响,提出了以失效节点率、活跃节点的失效覆盖邻居节点数、网络分支数、网络覆盖损失率等因素作为评价标准.该评价标准构成该类型网络的监测性能评价模型.结合网络结构给出了一种三角形网格化的方法,用来计算网络覆盖损失率的准确值.仿真结果表明在不同节点失效情况下,该评价标准能有效地评估网络监测性能受影响的程度.

Monitoring Performance Criterion for Triangle Grid-based Wireless Sensor Networks

In view of the problem of lacking targeted performance criterions for different structures of wireless sensor networks,the impact of node failure on the network monitoring performance is analyzed focusing on triangle grid-based wireless sensor networks.Some performance criterions,including the rate of failing node,the number of coverage neighbor nodes of active nodes,the number of network branches,and the degree of losing coverage are proposed.All these factors can be used to compose the monitoring performa...
