摘 要: 针对延迟容忍网络(delay-tolerant network,DTN)的社会化网络场景,提出了一种移动性辅助路由协议——基于分簇与位置的路由(cluster and location based routing,CLR)。在CLR协议中,快速移动节点收集与普通节点的历史相遇位置信息,计算普通节点之间的距离,为普通节点分簇,并充当簇之间的通信桥梁;簇内通信采用基于距离的贪婪算法。仿真结果表明,CLR协议在保证网络性能的同时能显著减少网络负载。
关 键 词: 计算机系统结构;延迟容忍网络;社群效应;历史相遇位置信息;分簇;网络负载

Abstract: Aiming at improving the transfer efficiency for delay-tolerant network (DTN) with social feature, one mobility-assisted routing protocol, i.e. cluster and location based routing (CLR), was proposed. In the protocol, the fast moving nodes collected the historical meeting position information of the static nodes, calculated the distance of the static nodes, divided the static nodes into clusters, and acted as communication bridges for clusters. In cluster, communication was based on the greedy algorithm of distance. Simulation results showed that the strategies used in CLR could improve the performance of network and reduce the network load.
Key words: computer architecture; delay tolerance network; community effect; historical meeting position information; clustering; network load
