Paper Abstract

The hybrid optical wireless network has gained interest for future access networks. In order to guarantee quality of service (QoS), especially for the multi-media services, resource management and scheduling mechanism become critical design issues in the hybrid optical wireless network. Various scheduling algorithms have been proposed in either optical (EPON) or wireless (WiMAX) domains. However, none of these algorithms has considered the end-to-end QoS for a connection communicating through both two domains. In this paper, we come up with an idea to modify the original signalling protocol in the optical domain, and use it to design a novel Integrated Optical Wireless Admission Control (IOW-AC) in an uplink scheduler. From both analysis and simulation, QoS requirement in terms of delay is guaranteed and the utilization of bandwidth resources is improved.
