Provision of QoS in heterogeneous wireless IP access networks

The Internet protocol is being deployed at an ever-increasing pace to offer connectivity to support a wide range of applications. Current research is targeting mobile hosts, and numerous research projects are considering the technologies needed to support the nomadic user. The IST BRAIN and MIND projects have studied the problems using a top-down approach, from user requirements through the application layer all the way to link layer specific issues. This paper presents the results of the study of quality of service provision at the IP layer, to offer service differentiation to application data flows, even over wireless networks.
