Abstract :
We analyze the quality of service (QoS) performance of different traffic classes in optical-wireless converged networks when different resource handling mechanisms are used. We show that in order to achieve the optimum QoS performance in the EPON-WiMAX converged network for all traffic classes, a proper combination of a dynamic bandwidth allocation algorithm, an intra ONU-BS (integrated optical network unit and WiMAX base station) scheduling algorithm, and a QoS mapping mechanism need to be implemented. We propose such a combination that includes novel intra ONU-BS scheduling algorithm which improves the QoS performance of all traffic classes of an EPON-WiMAX converged network.
