容迟网络中低资源消耗Advanced Epidemic路由算法

容迟网络（DTN）架构涵盖无线传感网络、Ad Hoc网络等，但其中高效节能的路由算法是一个亟须解决的问题。 与传统网络相比，DTN路由的主要目的是最大化消息送达的可能性。Epidemic算法简单但网络资源消耗较高。针对消息自身因素、连接机会、连接稳定性等方面进行改进，并在对仿真平台ONE的分析基础之上，对算法进行性能分析，总结出算法的优缺点。

Advanced Epidemic routing with low resource consumption in delay tolerant network

Delay Tolerant Network (DTN) architecture, covering wireless sensor networks and Ad Hoc networks, has very broad application prospects in military and scientific research. And it is emerging at the forefront of one of the new studies. But the study is still at its premature stage, and many mechanisms need to be developed or improved. In DTN, how to design an efficient routing algorithm is one of the key issues. Compared with traditional networks, the objective of DTN routing is not to transmit message at lowest cost, but to maximize the possibility of message delivery. Epidemic algorithm is simple but blind-routing strategy. This paper tried to improve the performance by using information of messages, connection opportunity and stability. Based on the analysis of the simulator ONE, I implemented the algorithm and analyzed the performance. At the end of the paper advantage and weakness were summarized.
