Abstract

Delay tolerant networks (DTNs) are characterized by intermittent node connectivity and unavailability of end-to-end paths for most of the time. Routing in such networks is a challenge because of these characteristics. Some existing routing protocols try to improve the delivery ratio by replicating some messages and hence perform poorly if the nodes have limited buffer space, or alternatively, if the number of messages is high. Some existing protocols also use the underlying movement pattern to improve routing efficiency. In many real life scenarios, movement patterns show repetitive contacts between nodes occurring in some time sequence. In this paper, we propose a probabilistic routing protocol that uses both the repetitive contacts and their time sequencing to improve routing. The protocol does not replicate any message and hence can work with low buffer size in mobile nodes. The novel feature of this protocol is the use of sequences of contacts which has not been used in earlier protocols. Simulation results show that the proposed protocol achieves high message delivery ratio with no message replication compared to some of the existing protocols.
时延容忍网络中基于接触排序的概率路由
延迟容忍网络(dtn)的特点是节点连接断断续续,端到端路径在大多数时间不可用。由于这些特点,在这样的网络中路由是一个挑战。一些现有的路由协议试图通过复制一些消息来提高传递率,因此,如果节点的缓冲区空间有限,或者消息数量很高,则性能很差。一些现有协议也使用底层移动模式来提高路由效率。在许多现实生活场景中,运动模式显示节点之间以某种时间顺序发生的重复接触。在本文中,我们提出了一种概率路由协议,该协议使用重复接触和它们的时间顺序来改进路由。该协议不复制任何消息,因此可以在移动节点中使用低缓冲区大小。该协议的新颖之处在于使用了早期协议中未使用的接触序列。仿真结果表明,与现有协议相比,该协议在没有消息复制的情况下实现了较高的消息传递率。
