基于故障检测的无线传感器反应网络故障恢复策略

A Fault Recovery Strategy Based on Wireless Sensor and Actor Network in Fault Detection

介绍了一种在反应节点发生故障后对内部网络连通性造成影响的情况下,重新恢复网络通信的策略。该方法首先用基于连通决定集的方法对故障节点进行检测,判断其故障是否对网络连通性造成影响,其结果决定是否启动故障恢复过程。在恢复过程中,根据规则的优先级,对故障节点的邻居节点进行选择,从而选择适合替换故障节点的候选者。

In this paper, a strategy to recover the network communication is introduced when the reaction node failed and affected the internal network connectivity. Firstly, this method can detect the fault nodes base on the method of connecting decision set, and determine whether the failure will impact on network connectivity,which decides whether to start the recovery process. In the recovery procesS, we select the neighbor nodes and find candidates for replacement of the fault nodes according to the rule priority.
