| Abstract(in English) | In ad-hoc 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. 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 wireless channel capture around the proxy host. In this paper, we propose two methods for resolving the wireless capture problem in the proxy-based TCP. Our proposed methods are adaptive rate control which resolves wireless capture in the second sub-session and intentional flow control which prevents wireless capture in the first sub-session. Our proposed methods has advantages for easy implementation because it can be implemented only in the proxy host and does not need any change in data link layer protocol. Performance evaluation results show that proxy-based TCP with our proposed methods outperforms conventional end-to-end TCP. |
