Multimedia applications in wireless networks are usually categorized into various classes according to their traffic patterns and differentiated Quality-of-Service (QoS) requirements. The traffic of heterogeneous multimedia applications often exhibits Long-Range Dependent (LRD) and Short-Range Dependent (SRD) properties, respectively. The integrated scheduling scheme that combines Priority Queuing...
The increasing demand for the coverage of high-speed wireless local area networks (WLANs) is driving the installation of a very large number of access points. Wireless mesh networks (WMNs) have emerged as a promising technology in next generation networks to provide economical and scalable broadband access to wireless interconnection of multiple access points which manage individual WLANs in order...
Active queue management (AQM) coupled with differentiated scheduling mechanism is an important and promising scheme for congestion control and quality-of-service (QoS) guarantee in communication networks. This paper develops a new analytical performance model for priority-based AQM subject to heterogeneous bursty traffic modelled by Markov-modulated Poisson processes (MMPP) and non-bursty traffic...
Recently there have been considerable interests focusing on the performance evaluation of IEEE 802.11e medium access control (MAC) protocols, which were proposed for supporting quality of services (QoS) in wireless local area networks (WLANs). Different from most existing work, this study has conducted comprehensive performance evaluation and analysis of the IEEE 802.11e enhanced distributed channel...
