针对延迟容忍网络中存在的数据传输时延较高、摆渡节点间协作性不高,以及如何最优分配摆渡节点等问题,提出一种基于位置信息的摆渡节点延迟容忍网络路由算法（ferries routing mechanism based on location information for delay tolerant network,FRLI）。基于节点位置信息,定义基于位置信息的数据传输机制,通过划分摆渡节点隶属的区域,根据摆渡节点在网络中的初始分布状况,合理分配网络中摆渡节点分布,通过交换彼此区域内缓存的网络节点信息,获取有利于当前区域内数据传输的有效信息,提高区域内数据传输效率;基于节点区域信息,确认目的节点是否属于当前区域后,直接将数据投递至网关节点,渐次...

To improve the problems that the average data transmission delay is high,coordination is poor between ferry nodes and how to best allocate ferry nodes for the special delay tolerant network,a ferries routing mechanism based on location information for delay tolerant network (FRLI) was proposed.The progressive data transmission strategy of location information was introduced,ferry nodes were distributed reasonably in the network,network node information was exchanged within each region ferries cache,accessing conductively to the effective current zone in the data transmission and improving the ...
