An Inter-channel and Intra-channel Dynamic Wavelength/Bandwidth Allocation Algorithm for Integrated Hybrid PON with Wireless Technologies for Next Generation Broadband Access Networks

Abstract—Optical and wireless technology integration schemes merge the high-speed and high-capacity of the optical networks with the low-cost, wide-coverage and mobility features of wireless counterparts for Subscriber Stations (SSs). It is also financially viable for the telecommunication service providers particularly in rural areas. In order to successfully integrate the two technologies, there are some technical concerns in terms of Architectural aspects, Physical Layer features and Media Access Control (MAC) related issues. This paper is mainly focused on the analysis of the key topics in MAC-related issues over the converged scenario and proposes an Inter-channel and Intra-channel Dynamic Wavelength/Bandwidth Allocation (IIDWBA) algorithm where the hybrid Passive Optical Network (PON) acts as a backhaul technology for the wireless counterpart. Performance of the proposed algorithm is evaluated through conducted simulation scenarios in terms of different Quality of Service (QoS) metrics where the IIDWBA algorithm shows a better performance when it is compared with the scenario in which it has not been employed
