Abstract

Due to the reusable characteristic of cache, proxy servers are widespread to improve the quality of network services. As popularity and maturity of wireless access technologies continue to grow, 3G/3.5G, Wi-Fi, or WiMAX mobile nodes (MNs) may keep moving across heterogeneous networks. It is unreasonable to let MNs retrieve cached data from the same proxy server along their traveling routes. Hence, proxy handoff is meant to help MNs switch their proxies dynamically. Regarding the realistic network environment, most proxies are provided by Internet service providers (ISP). Once a MN moves across the domain of one ISP, it can not access the data cached in the proxy. This kind of proxy access limitation obstructs cache cooperation and forwarding among proxies. This article is motivated to utilize the Session Initiation Protocol and the mobile agent concept to propose a proxy handoff framework for multi-ISP heterogeneous networks. Different strategies are designed to overcome proxy access limitation. The simulation results compare and analyze the differentiation among three proxy handoff strategies.
