Abstract

Recent advances in wireless technology are enabling the design and deployment of multiservice wireless networks. In order to be able to meet the QoS requirements of the various applications, it is essential to deploy QoS provisioning mechanisms. In this paper we present a QoS framework to support various types of services in a wireless networking environment. In particular, the proposed framework is used to design various QoS provisioning mechanisms for time-constrained variable bit-rate applications. Under this QoS framework we propose various Resource Request (RR) mechanisms. We carry out a comparative study of the proposed schemes. Our simulation results show the effectiveness of the mechanisms when supporting media streaming services, such as MPEG-4 video communications.
