摘要

针对 Epidemic 算法导致机会网络拥塞引发的路由可靠性问题，提出一种基于信任机制的改进Epidemic算法。通过构建节点之间的信任机制，提供具有足够可信度的节点作为消息的下一跳转发节点，使消息进行有限规模的泛洪传播。仿真实验结果和分析表明，改进后的Epidemic算法避免了泛洪机制引发的网络拥塞问题，并且在路由可靠性和传输性能上有一定的提高。

Abstract

Aiming at the problem of routing reliability caused by Epidemic algorithm

an improved Epidemic algorithm based on trust mechanism was proposed.Through the establishment of trust mechanism between nodes

this mechanism can provide sufficient trusted nodes as the next hop node of message forwarding

and can promote that the Epidemic algorithm performs the limited scope of flooding under the constraint of trust mechanism.Simulation results and analysis show that the improved Epidemic algorithm can avoid the network congestion caused by flooding mechanism

and the reliability of routing and transmission performance are improved to some extent.
