容迟网络中的路由算法研究及比较

容迟网络是一类新型的网络，根据不同的网络环境，容迟网络呈现不同的形式。在该类网络中，由于其具有较大且不定的时延以及网络拓扑结构频繁分裂的特性，使得传统的路由协议不能得到有效的利用。为此，路由问题即给出适合于容迟网络中有效的路由协议就成为容迟网络中的关键问题。本文主要针对近年来所提出的多种路由算法，进行分类剖析比较，并给出当前路由协议存在的有待研究解决的问题。

Research and Comparison on the Routing Algorithms of DTN

Delay tolerant network （DTN） is new kind of networks, according to different networking scenarios, DTN can present different forms. Because DTN has large and indefinite delay and its network topology has intermittently-connected characteristics, traditional routing protocol can not be utilized efficiently. So, routing solution becomes key problems of DTN. In this paper we mainly discuss some routing algorithms put forward recendy and classify and compare them one by one, in the end of the paper, we try to give some open problems of DTN routing.
