摘　　要：数据在网络中的传输需要网络协议的保障,同时网络协议的设计也需要结合通信的环境特征。TCP/IP协议设计的相关假设在有线网络或者节点间连接状况良好的无线网络中可以实现。在某些环境恶劣的受限通信场景中,TCP/IP协议体系难以完成数据传输的任务。为了满足多种需求、随时接入及不限地域的通信需要,引入容迟网络(DTN,Delay Tolerant Network)的概念。社会DTN网络通过无线连接,节点间的连接效能并不相同,对链路的性能进行评价,并作出定量分析,能够指导数据在网络中的传输。设计了基于链路效能的社会DTN网络路由算法——LABR。通过ONE平台仿真验证,对性能进行分析,并与现有路由算法进行对比。Data transmission in the network rely on network protocols,while the design of network protocols also require accommodation with the communication environmental characteristics.The design of TCP/IP protocol is based on wired network or wireless network nodes which are well connected.However,in some harsh challenged communication scenario,TCP/IP protocol system is difficult to complete the task of data transmission.In order to meet a variety of communication needs anytime and anywhere,DTN(Delay Tolerant Network)emerged.DTN social network is connected in wireless way,and the activity of connection between nodes is different.Through evaluation of the activity of the link,quantitative analysis can guide the data transmission in the network.Based on this,a new routing algorithm named Link Activity Based Routing(LABR)is proposed.The performance of LABR is analyzed and compared with other routing algorithms in Opportunistic Network Environment(ONE).
