Simulation of Integrated MAR in Wireless Network Architecture by using Higher-Level and Lower-Level Proxy Servers

The Higher-Level and Lower-Level Proxy servers is an effective solution to reduce Web traffic and integrated wireless network architecture using Proxy servers to support mobility management. The technique takes advantage of the existing functionalities of proxy servers to provide mobility support for applications such as Web browsing, HTTP and FTP, without modifying the IP protocol stack of the mobile host. The architecture uses proxy servers to force all packets originating from mobile hosts to a close-by mobility-aware router so that the latter can maintain active data connections during handoffs across different networks. By deploying multiple proxy and mobility-aware router pairs and by assigning mobile hosts to proxy servers dynamically, the proposed architecture provides efficient mobility management functionalities, and is inherently scalable. This paper describes performance and building simulation models for evaluating mobility of proxy servers. The basic idea of the proposed method is the system takes advantage of the existing proxy supports in network applications to maintain network connection during a handoff and to reduce Web traffic than existing scheme.
