| 摘 要： | 在延迟容忍网络中,基于配额的多拷贝路由通过对消息拷贝数量的限制来控制开销,如何在控制开销的前提下尽可能提高消息投递成功率是其需要解决的关键问题.文中首先分析了提高消息投递成功率的配额分配策略,然后据此提出一种基于投递概率预测的配额路由算法.该路由算法根据节点的本地信息预测到其它节点的投递概率,在复制消息时,根据节点间投...

| Abstract: | In the Delay Tolerant Network(DTN),the multiple copies routing scheme was proposed to improve message delivery ratios.Due to the large overhead which multiple copies bring,the quota-based routing algorithm limited the number of replicas to control overhead.In the quota-based routing scheme,one possible criticism is how to improve delivery ratios as much as possible.In this paper,the authors analyze the optimum strategy for replicas allocation to achieve the highest delivery ratios,and propose a Delivery Pro... |
