How Good Delayed Acknowledgement Effects Rate-Based Pacing TCP over Multi-hop Wireless Network

The expansion of wireless network has been a very attractive area of research. Many researches focus on the performance of TCP over wireless environment. This paper presents the simulation analysis of rate-based pacing TCP with the delayed acknowledgement enable and disable strategies in the wireless multi-hop network. We find out how good the delayed acknowledgement (ACK) strategy affects rate-based pacing TCP-Reno (Reno-RBP) and rate-based pacing TCP-Vegas (Vegas-RBP) with respect to packet loss rate, end-to-end delay, round trip time measurement and throughput. Our comparative analysis shows that, although the impact of the delayed ACK strategy has a positive impact on Reno-RBP, it negatively affects Vegas-RBP in some situations.
