“…A couple of surveys and tutorials related to error-control methods appeared in the literature of FSO communications, which mainly focused on the PHY layer solutions [23]- [34]. Khalighi et al reviewed several PHY layer error-control methods used in FSO-based terrestrial systems, including FEC code, spatial diversity technique, adaptive transmissions, relay-assisted cooperative transmissions, and hybrid FSO/RF schemes in [23].…”

“…Trichili et al [33] provided an up-to-date review of PHY error-control solutions, containing channel coding, diversity, adaptive optics, relay transmission, signal processing techniques, and hybrid FSO/RF, in terrestrial FSO communications. Most recently, Jahid et al [34] conducted a comprehensive survey on several PHY error-control solutions, including aperture averaging, adaptive optics, relay-aided transmissions, channel coding, cooperative diversity, and hybrid FSO/RF schemes, for both terrestrial and space networks. The aforementioned surveys with regards to error-control methods are summarized at a glance in Table II, which allows readers to capture the major Table III: Existing surveys/tutorials relating to link-layer retransmission protocols.…”

“…At the time of writing this paper, we realized that a detailed survey of link-layer error-control solutions and their cross-layer design is not available in the literature of FSO communications. Although these issues were briefly discussed in [24], [26], [34], these studies lack a comprehensive/indepth survey/tutorial for the issues because their main focus was the PHY error-control methods. In addition, among linklayer error-control solutions, retransmission-based methods, including ARQ and HARQ, have more degrees of freedom than ECC, making them a fertile research area in the domain of FSO communications.…”

“…While the link-layer retransmission protocols have been widely surveyed in the literature of RF communications [35]- [43] as summarized in Table III, the adoption of these protocols for RF systems can not be straightforwardly applied to the FSO ones. This is because there exist many fundamental specificities in the transmission protocols, fading channels, and modulation schemes of FSO systems that make them different from RF ones [34]. More explicitly, we have to point out the challenging issues when applying link-layer retransmission protocols in FSO systems compared to the RF ones.…”

“…It is important to note that the conventional uniform error model for RF systems uses the error structure of different frame transmissions that are assumed to be independent [43]. Moreover, as the FSO fading channel models are entirely different from those of RF [34], it would be essential to have a proper protocol design under the atmospheric turbulence conditions in terms of system performance optimizations.…”

Free space optical (FSO) communication has established a reputation for itself capable of delivering high-speed data services over long distances without exhausting radio frequency (RF) resources. FSO communication can be considered in different network scenarios, including inter-satellite/deep-space links, ground-station/vehicles, satellite/aerial links, and terrestrial links. It is expected to be one of the key enabling technologies for the next generation of 6G wireless networks. Nevertheless, despite the great potential of FSO communications, its performance suffers from various limitations and challenges: atmospheric turbulence, clouds, weather conditions, and pointing misalignment. The error-control solutions, including physical layer (PHY) and linklayer methods, aim to mitigate the transmission errors caused by such adverse issues. While the existing surveys on errorcontrol solutions in FSO systems primarily focussed on the PHY methods, we instead provide a review of link-layer solutions. In particular, we conduct an extensive literature survey of state-ofthe-art retransmission protocols, both automatic repeat request (ARQ) and hybrid ARQ (HARQ), for various FSO communication scenarios, including point-to-point terrestrial, cooperative, multi-hop relaying, hybrid FSO/RF, satellite/aerial, and deepspace systems. Furthermore, we provide a survey of recent literature and insightful discussion on the cross-layer design frameworks related to link-layer retransmission protocols in FSO communication networks. Finally, the lessons learned, design guidelines, related open issues, and future research directions are exposed.
