Enhancing Wireless Internet Links

We describe a novel link layer architecture to enhance the performance of Internet protocols over wireless links. The degraded performance of these links on the Internet and the inadequacy of existing approaches of overcoming these problems in a protocol independent manner, motivate our solution. Our link layer provides multiple services and performance feedback to higher layers, thus supporting adaptive protocols and applications. In addition, our approach can serve as the basis for future Internet evolution towards Quality of Service provision. We also describe our ongoing research and implementation directions.
