A pair of QoS oriented bandwidth allocation algorithms for both BS and SS in broadband wireless access (BWA) networks, are presented. These algorithms offer soft QoS provisioning by letting each class of service exploiting the available bandwidth considering the delay bounds of the exisiting connection's queues so that lower priority classes can get a reasonable minimum share of bandwidth. This method is taking advantage of a bonus allocation scheme while keeping the connection priorities in focus. The simulation results show that the proposed scheduler provides QoS support for different types of traffic classes whilst maintaining the standards of IEEE 802.16.
