Modifications for TCP Improvements Over Wireless Networks
In this paper, the authors provide modifications of TCP for better performances in wireless networks. The improvements can be classified in several categories according to the problems they address. In the main section, a proxy based solution called Radio Network Feedback - RNF is implemented in NS-2 and its characteristics are compared to a standard TCP Reno. The control structure in the proxy sets the window size according to the information for the momentary radio bandwidth and the queue size. The results of the simulations show that there are several key areas where the RNF solution clearly outperforms widely used TCP Reno and increases the radio link utilization.
