Channel Management for Multi-Service Traffic in Cellular Wireless Networks

摘要

Channel management aims to provide quality of service guarantees for mobile users while efficiently utilize limited radio spectrum. With the increasing demand for diverse services in wireless networks, channel management for multi-service traffic in wireless networks is important. To provide diverse broadband services in limited radio spectrum, previous literature has presented adaptive services which provide mobile users with good quality of services. This study considers channel management for multi-service traffic in wireless networks with adaptive services. A channel management scheme, namely, restricted sharing, is devised to provide multi-class traffic with quality of service guarantees while increase channel utilization as much as possible. An analysis is used to study the performance of the restricted sharing scheme. Three classes are considered in numerical results. Numerical results show that the restricted sharing scheme guarantees quality of service and achieves high channel utilization.
