延迟容忍网络中编码的动态控制

Dynamic control of Coding in Delay Tolerant Networks

Eitan Altman, Francesco De Pellegrini, Lucile Sassatelli

摘要:

延迟容忍网络(DTN)利用中继节点的移动性来补偿永久连接的缺乏,从而使彼此范围之外的节点之间能够通信。为了减少消息传递延迟,要传输的信息在网络中被复制。我们研究的复制机制,包括里德-所罗门型代码以及网络编码,以提高在给定的时间限制内成功交付的概率。我们提出了一种分析方法,使我们能够计算成功交付的概率。我们研究了编码对网络性能的影响,同时优化了路由参数。

英文摘要:

Delay tolerant Networks (DTNs) leverage the mobility of relay nodes to compensate for lack of permanent connectivity and thus enable communication between nodes that are out of range of each other. To decrease message delivery delay, the information to be transmitted is replicated in the network. We study replication mechanisms that include Reed-Solomon type codes as well as network coding in order to improve the probability of successful delivery within a given time limit. We propose an analytical approach that allows us to compute the probability of successful delivery. We study the effect of coding on the performance of the network while optimizing parameters that govern routing.
