Abstract
WiMAX is an emerging technology for next-generation wireless networks which supports a large number of users in an economic way. To achieve quality of service (QoS) requirements, an efficient and reliable scheduling algorithm is needed. The existing approaches in the literature have been proven to provide the best performance in allocating bandwidth to subscriber stations to maximize the throughput and ensure the constraints of delay in each class of traffic. In these approaches, starvation of lower priority class was not considered, which is of great significance in reality. In this paper, we have considered the starvation of lower priority classes to provide QoS requirement to each class of traffic in an acceptable way, and a bandwidth scheduling algorithm is proposed. A comparative study between the proposed scheduling algorithm and the existing scheduling algorithm shows the better performance in terms of maximizing the network throughput in given network, while minimizing the starvation of lower priority classes.
