For integration of Ethernet Passive Optical Network (EPON) and WiMAX (IEEE802.16), it is necessary to support End-To-End (ETE) Quality-of-Service (QoS) due to the heterogeneous media access control (MAC) features of EPON and WiMAX. To address this issue, this paper first presents a Hybrid Optical Network Units-Base Station (HOB) architecture that provides a basic structure to support QoS related functions. On the basis of HOB, the QoS-enabled Bandwidth Reservation Protocol (QBRP) is proposed to achieve ETE QoS by performing the cooperative bandwidth allocation and QoS mapping. The simulation results show that the QBRP outperforms the existing Multi-Hop Transmission Mechanism (MHTM) in terms of the packet delay, the packet delay variation (jitter), and the packet loss ratio.
