Quality of service support for multimedia applications in third generationmobile networks using adaptive scheduling

Third generation mobile network will support services such as video-telepho ny, video-conferencing and other multimedia applications. Therefore, this n etwork must provide quality of service (QoS) to these applications consiste nt with that offered by fixed networks. However, this is a very challenging task due to the instability of the wireless channel and the diverse qualit y of service requirements dictated by different multimedia applications. In this paper we introduce a resource allocation algorithm for the wireless d ownlink that takes into account the wireless channel characteristics, the Q oS required by the applications as well as a pricing value function. Our so lution is based on an adaptive scheduling algorithm originally developed fo r scheduling real-time processes during transient surges. This algorithm te nds to maximize the wireless network operator profit while satisfying the c ustomers' quality requests.
