QoS-aware mapping and scheduling for integrated CWDM-PON and WiMAX network

Abstract

Worldwide Interoperability for Microwave Access (WiMAX) has emerged as one of key technologies for wireless broadband access network while Coarse Wavelength Division Multiplexing-Passive Optical Network (CWDM-PON) is one of the potential solutions for future high speed broadband access network. Integrating both networks could enhance the whole network performance by allowing cost-effectiveness, higher capacity, wider coverage, better network flexibility and higher reliability. In this work, scheduling algorithm is proposed as means to maintain the Quality of Service (QoS) requirements of two different media whilst allocating the bandwidth to the subscribers. The NS-2 simulation results demonstrate how network performances of the integrated CWDM-PON and WiMAX networks are improved in terms of delay and throughput.
