With the increasing demand for multimedia services on wireless networks, it is important to optimise air interface parameters to maximise throughput and QoS. In this paper, we examine the effect of WiMAX burst mapping and Round Robin - based packet schedulers on multimedia traffic and network capacity. In this work, we have simulated the IEEE802.16e air interface to examine the downlink channel performance...
A wide range of emerging real-time services require different levels of Quality of Services (QoS) guarantees over wireless networks. Scheduling algorithms play a key role in meeting these QoS requirements. Most of research in this area have been focused on deterministic delay bounds and the statistical bounds of differentiated real-time services are not well known. This paper provides the mathematical...
We consider the problem of several users transmitting packets to a base station, and study an optimal scheduling formulation involving three communication layers, namely, the medium access control, link, and physical layers. We assume Markov models for the packet arrival processes and the channel gain processes. Perfect channel state information is assumed to be available at the transmitter and the...
