摘　　要：环境危害、能量耗尽、设备故障等原因常导致传感节点错误,影响无线传感网络(WSNs)的应用性能,缩短无线传感网络寿命。为解决传感节点错误问题,提出面向容错的基于簇的分布式FTCD路由。在初始阶段,传感节点利用离簇头(CH)的距离、簇头离基站(BS)的距离及簇头的剩余能量信息选择自己的簇头;在数据路由阶段,簇头以最小化能量消耗方式选择下一跳簇头,并提出容错处理。仿真实验结果表明,FTCD路由能有效应对簇头错误,提高了能量利用率,使其多方面的性能都得到显著提高。Sensor nodes are very prone to failure due to several factors such as environmental hazards, energy depletion and device failure, which affects the application performance of WSNs and the overall network lifetime. In order to solve the problem of sensor node failure, the paper proposes a fault-tolerant and clustering-based distributed （FTCD） rouging in WSNs. In the clustering phase, sensor nodes select its CH on the basis of the distance between sensor node and the CH, the distance from the CH to the base station, and the residual energy of the CH. In data routing phase, the CHs select their next hop neighbor CH in such a way that their energy consumption will be balanced and minimized. The simulation experiment shows that the FTCD roughing can cope with the sensor node failure effectively, and increase the energy efficiency so as to improve the performance in various other aspects.
