通过大量模拟实验分析比较了移动AdHoc网络中TCP—NewReno协议在不同路由协议(AODV,DSDV)和在不同移动模型(RW,SN)生成的移动场景中的性能,包括有效吞吐率,延迟,丢包率.结果表明,使用AODV协议比使用DSDV协议,TCP有更高的性能.TCP在SN生成的移动场景中比在RW生成的移动场景中有更稳定的性能.在传输层协议的性能评价中,建议使用多种移动模型,特别是SN这样具有现实意义的模型.
This paper proposed the evaluation and comparison of the TCP-Newreno performance in different mobile scenarios generated by Random Waypoint (RW) and Social Network (SN) mobility model. To our knowledge TCP performance in Social Network Mobility is discussed for the first time. The comparisons of the impact of AODV and DSDV routing protocols on the TCP performance through goodput, delay and drop rate are also given. The extensive simulation results and analysis show that the TCP has better performance over AODV than over DSDV. TCP has better stability in SN than in RW. We suggest that for evaluating transport layer protocol, it is better to use more mobility models, such as realistic and human-like mobility model - SN.
