Epidemic路由算法是一种多副本路由算法，在资源受限的情况下，会由于无限制的洪泛使得网络中存有大量的消息副本，消耗大量网络资源，导致网络性能下降。针对Epidemic路由算法中存在的问题，提出一种基于节点协作的Epidemic路由算法，该算法通过节点间相互的协作和一定策略抑制网络中副本数多的消息的转发机会，提高副本数少的消息的转发机会，进而控制网络中总的消息副本的增长，以此保证消息转发公平性和较好的网络性能。仿真结果表明，与传统的Epidemic路由算法和Prophet路由算法相比，该路由算法能显著提高消息的交付率，减少消息传输延迟和路由开销，有效提高了网络总体性能。

In resource-constrained scenarios, the multi-copy routing named Epidemic will cause the de-graded network performance due to the unrestricted flooding, which leads to lots of message copies in the network and a large consumption of network resources.In order to solve the problem, Epidemic based on node cooperation has been proposed.Through the collaboration of nodes and a certain strategic restrain of the forwarding opportunist of message with more copies, Epidemic thus improves the forwarding opportunist of message with fewer copies, and restrains the growth rate of total copies of the message in the network, which can ensure the fairness of message for-warding and better network performance.The simulation result shows that the proposed route can significantly im-prove the delivery rate, reduce transmission delay and the route overhead, improving the overall performance of net-work effectively.
