IIDWBA algorithm for integrated hybrid PON with wireless technologies for next generation broadband access networks

Abstract

Optical and wireless technology integration has been proposed as one of the most promising nominees for the next-generation broadband access networks for quite some time. Integration scheme merges the high-speed and high-capacity of the optical networks with the low-cost, wide-coverage and mobility features of the wireless counterparts for the Subscriber Stations (SSs). It is also financially viable for the telecommunication service providers, particularly in the rural area where the development of optical infrastructure or expansion of the existing telecommunication solutions such as Digital Subscriber Line (DSL), Cable Modem (CM) or T-1/E-1 networks are either too costly or unreachable. 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, which need to be addressed efficiently in order to provide the smooth end-to-end (e2e) integration. This paper is mainly focused upon the analysis of the key topics in MAC-related issues such as E2E wavelength/bandwidth requests and allocations over the converged scenario. It proposes an Inter-channel and Intra-channel Dynamic Wavelength/Bandwidth Allocation (IIDWBA) algorithm where the hybrid Passive Optical Network (PON) acts as a back haul technology for the wireless counterpart. The proposed algorithm works in three phases, namely, Initialisation, Intra-channel bandwidth allocations and Inter-channel bandwidth allocations and is capable of allocating wavelength/bandwidth efficiently and effectively over the converged scenario. Performance of the proposed algorithm is evaluated through conducted simulation scenarios under different simulation parameters, traffic patterns and load values. According to the captured results, IIDWBA algorithm shows a better performance when it is compared to the scenario in which it has not been employed

DyCaPPON: Dynamic circuit and packet passive optical network

“…Future research should examine the trade-offs arising from operating multiple upstream wavelength channels and combinations of fixed-or variable-duration polling cycles. An exciting future research direction is to extend the PON service further toward the individual user, e.g., by providing circuit and packet service on integrated PON and wireless access networks, such as [92]- [97], that reach individual mobile users or wireless sensor networks [98]- [100]. Further, exploring combined circuit and packet service in long-reach PONs with very long round trip propagation delays, which may require special protocol mechanisms, see e.g., [101]- [103], is an open research direction.…”

A Hybrid Bandwith Allocation Algorithm for EPON-WiMAX Integrated Networks Based on Auction Process

“…Scheme based on game theory approach has been proposed in [33] giving accentuation to the fairness provisioning. A common downside in [26][27][28][29][30][31][32][33] DBA schemes found in the literature is that they disregard the time of the coordination handle as a basic effect on the surveying execution. A prediction-aware DBA scheme has been proposed in in [34], assuming that a FiWi networks consists of an asymmetric (10G-EPON) and WiMAX base stations in the front end.…”

“…Again, fairness and power consumption are ignored. The DBA scheme introduced in [31] guarantees a minimum amount of bandwidth, while the rest is distributed among the wireless subscribers; however, allocation fairness and power efficiency are not considered. The DBA scheme introduced in [32], called WiMAX EPON DBA, guarantees QoS in a seamless manner across the optical and the wireless domains.…”
