Design and implementation of Java-based HTTP input channel for integrated WLAN and GPRS networks

HTTP is the most crucial protocol enabling client-server applications. With the Internet converging and becoming mobile accessible, to adaptively manage HTTP connection is challenging. This paper describes the design and implementation of architecture for Java-based HTTP input channel for multiaccess wireless networks. A HTTP input channel can adapt its behavior to the changing network status. Adaptation includes both sensible selecting and dynamic switching the underlying connection used, as well as to cope with disconnection situation. Experiments were performed in a GPRS-WLAN integrated environment to demonstrate the operational correctness of the architecture. Performance metrics were measured and analyzed.
