An adaptive dual-threshold power saving mechanism in WiMAX

In the energy saving mechanism with random delay in broadband wireless network, an adaptive algorithm based on the dual-threshold and dynamic scheduling model is presented. First, to solve the demand assignment problem of bandwidth allocation and improve the system overall performance in broadband wireless network, using dynamic scheduling method and best-effort and non-real-time polling service traffic are analyzed. Then, an adaptive dual-threshold PSM for WiMAX is proposed, which not only tunes the tradeoff to satisfy various QoS requirements, but also makes adaptive adjustment based on traffic. Finally, Simulation results show that the mechanism has superior performance in comparison with the ideal assumption of Poisson arriving.
