一种基于端到端的Ad Hoc网络TCP性能改进方案

Improving TCP performance for mobile ad hoc networks through employing end-to-end identification

由于Ad Hoc网络环境所具有的特殊性,使传统的传输控制协议(TCP)已不再适合这样的环境。在总结分析现有的Ad Hoc网络中TCP性能的改进方案基础上,文章提出一种新的基于端到端检测方法的TCP改进方案,该方案利用数据包的单向传输延迟特性,让接收端检测网络状态,然后通过回送的ACK数据包携带网络状态信息以便让发送端采取合理措施;仿真结果验证了该方案是有效的。

The traditional TCP protocol is not appropriate for the speciality of ad hoc network environment. In this paper, a TCP improving scheme based on end-to-end identification is proposed on the basis of analysis of present ＇schemes. Using the feature of data＇s one-way transmission latency, this scheme firstly calls the receiver side to identify the network state. Then the sender side will take reasonable measures in light of network state information carried by back ACK data package. The simulation result has proved the feasibility and efficiency of the proposal.
