A novel hybrid dynamic bandwidth allocation and scheduling scheme for the integrated EPON and WiMAX architecture

Abstract

The integrated architecture of complementary Ethernet Passive Optical Network (EPON) and Worldwide Interoperability for Microwave Access (WiMAX) technologies combine the benefits of optical fiber capacity and wireless network mobility, which will become one of the promising broadband access technologies for next-generation network. In this paper, we propose a novel hybrid dynamic bandwidth allocation (DBA) and scheduling scheme for the integrated EPON and WiMAX in the access network to support quality of service (QoS) and class of service (CoS). The simulation results demonstrate that the proposed scheduling scheme enhanced performance in terms of drop probability, average queue length and average end-to-end packet delay, respectively.
