Connection Sharing in an Ad Hoc Wireless Network among Collaborating Hosts
Maria Papadopouli, Henning G. Schulzrinne · 1999
We present an architecture that enables network connection sharing in an environment of mobile, wireless, collaborating hosts. Dual-homed hosts with wireless connection to the Internet share their connection with other hosts of the collaborating group by acting as temporal gateways. The system aims to increase data availability and quality of service while achieving load balancing across the gateways. We focus on collaborative applications that support scalable, multimedia, streaming data, such as layered video. We discuss the main components of the system, namely, admission control, gateway selection, measurement of the gateway tra#c and the announcement policy. Finally, we present the simulation results to quantify the system performance. 1 Introduction Light-weight laptops and PDAs, the deployment of wireless networks and services, and the popularity of the Internet make mobile computing attractive. These technologies will enable users to connect to the Internet anytime an...
