Abstract:
Worldwide Interoperability for Microwave Access (WiMAX) networks provide wireless broadband internet access, interoperability, while decrease the entrance barrier in mobile communications sector, and offer services comparable to those of the emerging 4G technology. Τhe standard 802.16, upon which WiMAX networks are based, has not designated any particular scheduling algorithm, allowing each provider to develop its own. However, existing scheduling algorithms take into account the Quality of Service (QoS), fairness and other parameters, but do not provide Quality of Experience (QoE). For this reason, in this paper two different approaches are proposed in order to provide QoE, especially for the rtPS WiMAX service. Simulation results show that by applying different policies the QoE provided to the WiMAX users is improved.
