Abstract
A method for dynamically locating a wireless TCP proxy in a routing path in a wired/wireless integrated network is provided. A proxy for a mobile host transmits a proxy change request to a first higher-level proxy if a mobility of the mobile host is larger than a mobility threshold that is preset in the proxy. The first higher-level proxy determines whether the mobility of the mobile host is larger than a mobility threshold that is preset in the first higher-level proxy. The first higher-level proxy transmits a proxy change request packet to a second higher-level proxy if the mobility of the mobile host is larger than the mobility threshold of the first higher-level proxy. The second higher-level proxy selectively permits the proxy change if the mobility of the mobile host is smaller than the mobility threshold of the second higher-level proxy.
