摘　　要：研究了传统拜占庭容错方案并针对无线传感器网络的特定环境加以改进,减少了传统方案中网络节点间消息交换轮数,提高了效率并降低了通信开销和能量消耗,仿真结果表明:设计的方案在使所有正常网络节点达成一致的同时,其使用的消息交换轮数与传统拜占庭方案相比有显著的下降.This paper designs an improved byzantine fault-tolerant scheme in allusion to the specific environment of wireless sensor networks .Compared to the traditional byzantine scheme ,this scheme can reduce the number of rounds of messages exchange greatly between network nodes so that improving the efficiency and reducing communication overhead and energy consumption .Simulation results show that by using the improved fault-tolerant scheme ,not only can all the normal network nodes reach an agreement ,but also the number of rounds of messages exchange are much less than that of traditional byzantine scheme .
