一种基于好友簇的社交网络中的时延容忍路由协议

摘要

Social network is a kind of wireless network which consists of portable communication devices. Generally, it has large scale,complcx structure and rapidly changed topology. It is a classic application scenario of delay tolerant networks. A network topology model was presented based on node's friend cluster on social networks. An efficient cluster based delay tolerant routing protocol was proposed for this topology model. The experiment proves that based on the cluster model, the proposed routing protocol can not only guarantee routing performance but also avoid consumption of network resources caused by uncontrolled epidemic packet copies.%社交网络是一种以便携式移动通信设备为节点的无线网络,通常由于其规模较大、结构复杂并且拓扑变化频繁,而成为时延容忍网络的一个典型应用场景.通过分析社交网络的特性,构建了基于好友群组的网络拓扑模型,并基于该模型,提出了一种基于簇结构的时延容忍路由协议.通过实验证明了该路由协议可以在保证较高路由性能的前提下有效控制由于数据副本传染造成的对网络资源的消耗.
