“…However, these approaches do not consider an optimal joint resource allocation which decreases the channel utilization and increases the mean packet delay. Further, in literature many algorithms have been proposed for data transfer [19], [20] based on the interleaved polling with adaptive cycle time (IPACT) [21]. However, these algorithms can not be used for RoF network due to the joint resource allocation in optical and wireless part of the network.…”

The oncoming Internet-of-things (IoT) applications and smart machine-to-machine (M2M) communication lead to an enormous increase in network traffic. To meet the escalating demands of these time-critical applications, we need a hybrid optical-wireless network, for which the radio-over-fiber (RoF) technology is a promising candidate. These networks need to support the stringent delay requirements of the above applications for a large number of mobile users. However, the existing user registration and identification approaches for these networks are not efficient for a high user density and cannot keep the overall mean delay within the permissible limit for such applications. In this article, we present a hybrid medium access control (MAC) protocol for the RoF network, for which we propose hybrid user identification and neighbor-aware hybrid user identification algorithms for high user density. Further, the MAC protocol uses a gated polling method for data transfer. Moreover, we propose an analytical delay model for the hybrid MAC protocol, which gives overall end-to-end mean delay considering user identification and data transfer. We verify it with the results obtained from the simulations. Finally, we evaluate the mean delay and packet loss rate of the proposed algorithms by varying the network load, user density, and fiber length and benchmark the performance of the proposed algorithm with the state-of-the-art (SoA).

“…In [ 10 ], a mathematical analysis of the bandwidth allocation schemes with excess distribution was provided by using a discrete-time Markov chain model. In [ 11 ], the delay produced by various excess distribution policies was evaluated. In [ 14 ], an analytical performance analysis on the deterministic delay bound for high and medium-priority traffic was presented.…”

Resources of Passive Optical Networks (PONs) can be shared by a diverse spectrum of customers such as residential users, business subscribers, mobile network operators, and service providers. A PON customer can rent one or several Optical Network Units (ONUs) from an Infrastructure Service Provider. The ONUs of a customer (multi-ONU customer) can be subject to large spatiotemporal traffic variability, resulting in underutilization of particular ONUs and overutilization of others. The Interleaved Polling with Adaptive Cycle Time with Multi-ONU SLAs support ( MOS-IPACT ) algorithm has been recently proposed to promote the redistribution of unused bandwidth of underloaded ONUs of a multi-ONU customer. This paper introduces an analytical model to evaluate the duration of idle periods in bandwidth usage, as well as a performance evaluation of the MOS-IPACT algorithm in networks with traditional and multi-ONU customers. Numerical results show that the MOS-IPACT algorithm efficiently distributes the excess bandwidth among the ONUs of multi-ONU customers without compromising the bandwidth availability.
