摘要： 提出了一种基于阶跃度的健壮声誉机制。该机制成功消除了由于节点勾结引起的声誉值误判，提高了声誉机制的健壮性。且在进行声誉值计算时，综合了历史因素。并将该机制应用于组播路由中，提出了一种基于声誉机制的概率组播路由算法RBPMRP。实验证明，在网络自私节点增多的情况下，该算法能显著提高包的平均传输率。

Abstract: This paper proposes a robust reputation mechanism which eliminates misjudged reputation value caused by the node’s collusion behavior. It also considers the history factor when calculating the reputation value, and brings it in multicast routing for ad hoc networks. A new probabilistic multicast routing algorithm RBPMRP based on the new reputation mechanism is proposed. The simulation shows the new algorithm performs better than ODMRP especially when selfish nodes increase.
