MANET TCP-Vegas跳数自适应算法的设计与实现
DESIGN AND IMPLEMENTATION OF MANET TCP VEGAS-HOPS ADAPTIVE ALGORITHM
摘要
Abstract
TCP Vegas is a kind of congestion control algorithm designed for wired network environment, but it has many problems in MA NET application. This paper presents a new algorithm named TCP Vegas-HA (TCP Vegas-Hops Adaptive) to improve the performance of TCP Vegas in MANET. This algorithm tests and obtains a group of optimal threshold value in different number of hops and node caches and uses them as empirical values, and introduces hops adaptive mechanism to new congestion control method. Also for the issue that the minimum round-trip time (baseRTT) can not accurately measure when the router changes, we present a new measurement method using these empirical values. Results of the simulation on the algorithm show that it has great adaptability against the variation of mobile network, and can effective ly increase the TCP Vegas throughput in MANET.关键词
