<title>Dynamic quality-of-service management in wireless multimedia networks</title>

Abstract

The provisioning of quality of service (QoS) in future wireless communication networks is a complex problem due to the presence of changing network connectivity, user mobility, and shared, noisy, highly variable and limited communication links. In this paper, we propose a QoS management framework in wireless multimedia networks. A new comprehensive service model considering both traffic characteristics and user mobility for wireless multimedia networks is proposed. Based on this proposed service model, adaptive resource scheduling, admission control and resource reservation schemes are applied appropriately. Simulation results show that the proposed scheme can achieve higher network utilization and the resulting multimedia traffic can get better quality of service guarantees at different levels.
