Performance Evaluation of Window Size in Proxy-based TCP for Multi-hop Wireless Networks
Yuta Yamamoto, Nobuhiko Itoh, Miki Yamamoto (Kansai Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) In multihop wireless networks, a TCP session can obtain very low throughput with increase of the number of hops. One promising way to resolve this technical problem of TCP throughput degradation is proxy-based TCP. In proxy-based TCP, an end-to-end TCP session is divided by (an) intermediate proxy host(s), which leads to reduction of RTT of each divided session and improvement of TCP throughput. However, our current studies show that proxy-based TCP surprisingly does not bring performance improvement and obtain lower throughput than conventional end-to-end TCP. The reason for this degradation is bulk transmission of segments by sender and proxy host. In this paper, we introduce intentional flow control method which prevents bulk transmission of segments. In intentional flow control method, proxy host and destination host intentionally returns given advertised window size. Performance evaluation results show that keeping a small advertised window size that proxy host returns
effectively decreases bulk transmission of segments.
