摘要
首先指出了Ad Hoc分群网络中节点故障对网络的影响,着重分析了群首节点、网关节点发生故障时所导致的网络分割,使得通信受阻,并针对这一现象提出了重新选举关键节点的补偿算法,最后对补偿前后的网络性能进行仿真、比较,结果表明采用这一算法的网络有较好的鲁棒性,性能明显优于补偿前。
The influence of nodes failure on the Ad Hoe network is described with emphasis on the disconnection caused by failure of cluster - heads or gateway nodes. To solve this problem, a re - election algorithm is presented, and the result of simulation and comparison shows that the network with robustness has obvious advantage over what it was.
