Traffic from such applications is normally treated as high-priority in contrast to non delay sensitive applications such as FTP or e-mail, which are largely delay tolerant and have their flows treated as low-priority in the network. This paper analyses the performance behaviour of a recently proposed QoS model, notably LWQ, with respect to the number of high priority flows under a variety of mobility conditions. Our simulation results reveal that the number of high priority flows and different mobility states have a critical impact on the mean end-to-end delay and throughput of high priority traffic achieved by the LWQ QoS model. </ABSTRACT></RECORD></RECORDS></XML>
