容迟/容断网络(DTN)主要是为了解决节点间距离远、信道条件恶劣所导致的大时延、高误码率问题而提出的,在此通信环境下,经典的互联网协议已不再适用。文章在简介DTN协议的基础上,根据节点连接的确定与否,将现存的主流路由算法分为确定性路由和随机性路由,并结合DTN路由的评估参数,对一些算法的优缺点进行分析、对比、总结。
The DTN is mainly designed to solve the problem of large delay and high bit error rate caused by the long distance between nodes and poor channel conditions. In this communication environment, the classic Internet protocol no longer exists Be applicable. Based on the introduction of DTN protocol, this paper divides the existing mainstream routing algorithms into deterministic routing and stochastic routing based on the determination of node connections. Combined with the evaluation parameters of DTN routing, the advantages and disadvantages of some algorithms are analyzed. Compare, summarize.
