TCP is a transport protocol formally designed for the wired network and it is known to suffer from performance degradation in mobile wireless environment.In this paper,the authors propose modifications to the congestion avoidance mechanism of the TCP Vegas to overcome these limitations.The solution is depended on average and variance of round trip time,TCP data sender may utilize different congestion avoidance algorithms to optimize congestion window size,aims is to improve ad hoc network throughput.Simulation results show the algorithm is able to overcome several of the identified problems-it can obtain more throughput than TCP Reno and TCP Vegas.
