摘 要

近年来，由于移动便携式通信设备的广泛普及和不断更新换代，移动社会网络在日常生活中变得越来越普遍，并受到了社会各界越来越多的关注。为了有效发挥移动社会网络的优势，提高用户体验质量以及应用的服务质量，信息转发的路由问题至关重要。作为一种特殊的延时容忍网络，移动社会网络具有延迟容忍网络的时变性、间歇性连通和端到端不稳定等特点，源节点和目的节点之间不存在一条完整的通信路径，是由具有大量社会特性的移动节点组成的网络。而且随着移动社会网络动态性的不断增强，加之现代人们通信需求量的急剧增加，计算机网络以及传统有线网络中的路由信息协议（RIP）和开放式最短路径互连（OSPF）等路由协议已经满足人们的现实需求。而移动网络不要求网络全连通的特点更加符合如今实际应用环境下的自组网需求，因此成为近年来的研究热点。

基于此，本文对目前在移动社会网络中常用的路由协议及其研究现状进行了梳理和总结，并对其中的Epidemic路由、Simbet路由、Prophet路由和PRP路由这四种典型的路由协议的工作原理和和实现方法进行了详细论述。而后基于Matlab 仿真平台对这四种典型路由协议进行了仿真实验，并从平均网络时延、信息传递成功率、数据包平均转发跳数以及网络开销比等几个方面，对这四种典型路由协议的性能进行了相应评价和比较分析。最后对基于社会特征的路由协议的未来发展趋势进行了展望。

Abstract

In recent years, due to the widespread popularity and continuous upgrading of mobile portable communication equipment, mobile social network has become more and more common in daily life, and has attracted more and more attention from all walks of life. In order to give full play to the advantages of mobile social network effectively and improve the user experience quality and application service quality, the routing problem of information forwarding is very important. As a special delay-tolerant network, mobile social network has the characteristics of time-varying intermittent connectivity and end-to-end instability of the delay-tolerant network. There is no complete communication path between the source node and the destination node, and it is a network composed of mobile nodes with a lot of social characteristics. Besides, with the continuous enhancement of mobile social network dynamic, coupled with the rapid increase of modern people's communication demand, computer network and traditional wired network routing information protocol (RIP) and open shortest path interconnection (OSPF) and other routing protocols have met people's practical needs. The feature that mobile network does not require fully connected network is more in line with the demand of Ad Hoc network under the actual application environment, so it has become a research hotspot in recent years.

In this paper, the common routing protocols in mobile social networks and their research status are summarized, and the working principles and implementation methods of four typical routing protocols, namely, the Epidemic, the Simbet, the Prophet and the PRP, are discussed in detail. Then, the simulation experiments of these four typical routing protocols are carried out based on Matlab simulation platform, and the performance of these four typical routing protocols is evaluated and compared from the aspects of average network delay, information transfer success rate, average packet forwarding hop and network overhead ratio. Finally, the future development trend of social feature-based routing protocols is prospected.
