Introducing quality-of-service and traffic classes into wireless mobile networks

Abstract

1. ~STWCT Rwent developments in wireless conummimtions have made it possible to provide mtitimedia services for mobtie users. However, mtitimedia servic~that is a m-e of different content ~es including te~ images, audio, and vide=ver wireless W require that the underlying wireless infrastructure supports some kind of Q@tyof-Service concepts and Werent trtic classes. Since many of the current wireless technologies do not support those concepts, we introduce a way of adapting mobtie wireless networks so that some aspects of Qutity-ofService and traffic classw -be supported even if the underlying infrastructure does not support them. Our Nlobfle Network Adapters can overcome most of the titations due to protocol architectures. However, they m not augment the physid characteristic of the underlying technology but they try to use the avtiable resources in the most appropriate way. Our prototype implementation indicates that priori@based mtitipletig of traffic is useti for delivering rd-time and non-rdtime data to and from a mobde terminal. Our solution is able to support both seandess and
