Eliminating Backhaul Bottlenecks for Opportunistically Encountered Wi-Fi Hotspots

摘要

Wi-Fi access points can be found in any urban environment and have the potential to be a source of useful bandwidth even for users that are only in range for short periods of time. In this paper, we describe how in-motion networking is capable of exploiting short connection opportunities and transferring significant amounts of data by using only open or community access points. We describe the issues facing the in-motion user of today and present a protocol that is capable of eliminating backhaul bottlenecks at the access point's connection to the Internet. We describe and present the results of our implementation with measurements in an urban area of a city.
