In wireless personal area networks (WPANs), a successful design of scheduling scheme is critical for video traffic in QoS guarantee and efficient channel resource utilization. In this paper, we propose a novel cross-layer scheduling scheme for MPEG traffic in high speed WPANs. The scheme aims at introducing robust improvements to MPEG traffic scheduling by taking most advantages of traffic characteristic...
Call admission control (CAC) is a key factor in quality of service (QoS) provisioning for multimedia service in modern network. Lots of CAC schemes aim to satisfy QoS requirement and upgrade network utilization, but they ignore the fairness principle in network. Directly and simply using these schemes, it will appear the phenomenon that the narrow band calls block the broad band calls. The common...
Modern network is expected to support multimedia traffic, therefore how to guarantee the QoS of multimedia network is the emerging technology. CAC (call admission control) plays an important role in the QoS guarantee of multimedia network. Noticing that many CAC schemes aim to satisfying QoS requirement and upgrading network utilization, but they ignore the fairness principle in network. Directly...
With the development of differentiated services and multimedia services of network, a multi-priority delay reservation admission control scheme is proposed. In this scheme, different delay threshold of different traffic class is statistically derived. Through computed delay threshold, the admission of different traffic was controlled so as to provide their required service. Numerical results show...
