In this paper, a method of enhancing the proxy server is proposed, by which the relay function for com-pensating the connection can be established after the host move. This system consists of Mobile Hosts (MH) with the function of automatic sockets' switching, and Proxy/Relay server operated as an Access Point (AP). TCP connection is divided into plurality by this, and congestion control and flow control for each medium are separated. As a result, communication performance is improved, and maintenance of TCP connection can be realized by a slight modification to a wired network. After the implementation of the proposed server, we measured throughput, and for users movement from cell to cell, validity was confirmed for this methods.
