Eliminating Backhaul Bottlenecks for Opportunistically Encountered Wi-Fi Hotspots

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.
