摘　　要：针对工业无线传感器网络中的干扰攻击问题,得出一种基于WirelessHART图路由的被干扰攻击节点路由恢复机制。通过干扰攻击检测方法获取被干扰攻击节点与干扰攻击区域,利用非协调跳频扩频技术生成被干扰攻击节点与周围节点的跳频序列,从而进行传统跳频扩频,对被干扰攻击节点进行再检测,结合路由代价与WirelessHART图路由算法将被干扰攻击节点恢复到网络中。仿真结果表明路由恢复机制能够帮助被干扰攻击节点消除干扰攻击影响,并在保证吞吐量的情况下成功加入到网络中。Aiming at the jamming attacks in the industrial wireless sensor networks, a route recovery mechanism based on the WirelessHART graph routing is proposed. The jamming attack detection method is used to obtain the node and area being attacked by the jamming attack, the uncoordinated frequency hopping spread spectrum is used to generate the frequency hopping sequence of the node of being attacked by the jamming attack and that of the surrounding nodes, so that the traditional frequency hopping spread spectrum is performed on the nodes. Detects again, and combines the routing cost and the WirelessHART graph routing algorithm to restore the node to the network. The simulation results show that the route recovery mechanism can help the nodes to eliminate the influence of the interference attacks and successfully join the network under the condition of the ensuring throughput.
