“…Existing MAC schemes for PSC networks, including preallocationbased [8,9] and reservation-based [10][11][12][13][14][15][16][17] schemes, exhibit various performance merits and weaknesses. Preallocation-based schemes predetermine channel resources for each source-destination pair (S-D pair).…”

“…Of the existing reservation-based MAC schemes, few are based on packet-by-packet scheduling techniques [16][17][18] that enable fine-grained on-demand channel allocation and take advantage of statistical multiplexing. Such schemes further enhance system performance by decreasing the control-signal overheads.…”

“…For example, [16] adapts a control frame size with traffic loads, whereas MultiS-Net [18] employs a limited-size control slot design (whose length is equivalent to one data slot). References [16] and [17] have used multiple fixed-tuned transceivers, resulting in nonscalable designs and a large quantity of bandwidth that might be wasted using multiple control channels. Among these schemes, MultiS-Net proposes a cost-effective and scalable solution by equipping each node with only one pair of tunable transceivers (TT-TR).…”

A passive star-coupled (PSC) optical wavelength division multiplexing (WDM) network is considered a promising candidate for optical backhaul particularly in densely populated urban areas. In this paper, we present the access and control system design for wireless backhaul transmission over a PSC wavelength division multiple access (WDMA) network. We employ an in-band controlsignal technique, providing dedicated control slot access, and the length of the control slot is minimized and unconstrained by the length of a data slot, aiming at offering thorough control information and maximizing the system performance. A packet-by-packet, reservation-based, and frame-basis medium access control (MAC) scheme is presented. The MAC scheme ensures round-robin scheduling to flexibly transmit data packets within a data frame by simply adopting two initial variables. The simulation results show that the network achieves exceptionally high system performance when each node is equipped with only one tunable transmitter and one fixed-tuned receiver for uniform destination traffic scenarios. In a client/server traffic scenario, only the server node (which receives an additional proportion of the entire network traffic) is upgraded by replacing the fixed-tuned receiver with a fast tunable receiver; thus, exceptionally high delay-throughput performance is maintained, and the most cost-effective solutions are proposed.Index Terms-Medium access control (MAC); Optical backhaul; Passive star coupler (PSC); Wavelength division multiplexing (WDM).
