摘要： Because nodes in DTN might be interconnected using more than one type of underlying network technology, a DTN is best described abstractly using a multigraph. Edges in this graph are, in general, time... 阅读全文

摘要： Three relative priority classes have been defined to date. These priority classes typically imply some relative scheduling prioritization among bundles in queue at a sender. Bulk.Bulk bundles are ship... 阅读全文

摘要： 本文是SAC2009会议上的一篇录用论文。通过节点间的历史联系信息来创建邻居索引从而决定最合适的消息转发路径。基于Dartmouth College 实际网络场景的仿真表明，NECTAR与传染路由及PROPHET路由相比，能够传输更多的消息并且消耗更少的网络资源。 NECTAR路由算法总体上可以分为以下三个步骤：1，NI（Neighborhood Index）计算；2，消息调试策略；3，消息丢弃策... 阅读全文

摘要： PROPHET通过节点间的历史相遇信息来估计传输概率。它使用一个称为传输预测值Pa,b的参数作为路由度量，表示将消息从节点a传输到上的节点b的传输概率。假设节点a要将消息m传输到目的节点d，若节点a与节点b相遇，仅当Pb,d≥Pa,d时，a才将消息转发给节点b。 Pa,b的计算包括三个部分。当两个节点相遇时，彼此都更新各自的传输预测值： P(a,b) = P(a,b)old + (1-P(a,... 阅读全文

摘要： “An Optimal Probabilistic Forwarding Protocol in Delay Tolerant Networks”是MobiHoc2009的关于DTN路由的一篇文章，作者为Jie Wu教授和他的一位博士生。文中基于最优停止理论提出了一种新的路由算法(Optimal Probabilistic Forwarding，OPF)。 文章中首先提出了... 阅读全文
