Abstract
The increasing demand for multimedia communication over wireless platform necessitates the QoS-aware packet scheduling schemes in Broadband Wireless Access (BWA) networks. This paper deals with the analysis of queue size of QoS-aware Weighted Hybrid Packet Scheduling Schemes (WHPSS) for heterogeneous traffic classes in BWA networks. By categorizing the heterogeneous traffics of BWA networks into several classes (i.e. Class-1, Class-2, Class-3) depending upon their QoS requirement, we analyze the effect of queue size in WHPSS using three dimensional Continuous Time Markov Chain (CTMC) model. The analysis has been carried out with respect to the several performance parameters such as queuing delay, packet loss rate and throughput. This paper aims to observe the effect of queue size for each traffic flow to maximize the throughput of the network under the specified constraint of queuing delay and packet loss rate. Thus, the analysis helps to determine suitable queue size in the BWA network under varied traffic condition satisfying the required QoS constraints.
