摘　　要：为对抗来自无线传感器网络(wireless sensor network,WSN)内部节点的恶意攻击,提出一种基于分布式信任评价模型的能量优化安全路由协议(energy-optimized secure routing,EOSR)来识别和隔离恶意节点。设计一个多因素的路由策略,综合考虑节点的信任水平、剩余能量及路径长度,确保数据通过可信节点传输,均衡可信节点之间的能耗。通过仿真对比现有的路由算法,EOSR协议在能量消耗、吞吐量和网络存活期上显示出了更优的性能。To counter misbehavior attacks from wireless sensor network internal node,the energy-optimized secure routing protocol(EOSR)that exploited a distributed trust model for discovering and isolating misbehaving nodes was presented.A multi-factor routing strategy that took the trust level,residual energy,and hop-counts of path into consideration was employed while making routing decisions.This strategy not only ensured data dissemination via trusted nodes,but also balanced out energy consumption among trusted nodes.Demonstrating by simulation results,EOSR achieves improved performance in terms of energy consumption,throughput and network lifetime as compared to existing routing protocols.
