Mixing the wireless medium with fibre optics can form a new communication system called a radio-over-fibre (RoF) network; it is a promising solution that can provide high bandwidth and a reliable connection between numerous sensors in wireless sensor networks (WSN) and the central office (base station) within a particular area. This paper first design and discusses new paradigms of fire detection in the IoT environment using RoF technology. Secondly, this paper covers the distribution of remote antenna unit (DRAU) architecture within RoF-IoT. Finally, best remote antennas unit selection (BRAUS) of distributed RAUs architecture protocols utilizing new selection metrics are proposed. Two important metrics have been analysed and mathematically modelled, outage probability and bandwidth efficiency, respectively. Both metrics have been analysed as a function of the distance, number of RAUs, fibre optic attenuation, and path loss factor. Based on the simulation and numerical analysis, the outage probability of proposed protocols reduced by 65% compared to recent work, in addition, the bandwidth efficiency of the proposed protocol is increased by 34% compared to recent work.

“…Such an increase in the volume of the data rates is putting pressure on the existing radio frequency (RF) based communication networks, which has resulted in spectral congestions. In order to meet this challenge and ensure sufficient telecommunications networks resources for all at any times and any places, the services providers have considered the use of millimeter-wave (mmW) RF combined with optical fiber technologies, this option is one of the most attractive methods for fifth-generation (5G) wireless networks because of the huge bandwidth for highspeed mobile communications [2,3]. In radio over fiber (RoF) systems, the light carrier signal is modulated by the high-frequency RF signal for transmission over an optical fiber [4].…”

The radio over fiber (RoF) technology combines the advantages of radio frequency (RF) and optical communication systems. Hybrid RoF and radio over free space optics (RoFSO) is a solution for the last mile access networks in urban areas and in areas where installation of RoF links is impractical and costly. In this work we introduce a 4-, 16-and 64-quadrature amplitude modulation (QAM) hybrid RoF-RoFSO communication system and investigated the inter-channel interference and the effects of atmospheric turbulence on the FSO section of the link.

Underwater sensor networks (UWSNs) are of interest to gather data from underwater sensor nodes (SNs) and deliver information to a terrestrial access point (AP) in the uplink transmission, and transfer data from the AP to the SNs in the downlink transmission. In this paper, we investigate a triplehop UWSN in which autonomous underwater vehicle (AUV) and unmanned aerial vehicle (UAV) relays enable end-to-end communications between the SNs and the AP. It is assumed that the SN-AUV, AUV-UAV, and UAV-AP links are deployed by underwater optical communication (UWOC), free-space optic (FSO), and radio frequency (RF) technologies, respectively. Two scenarios are proposed for the FSO uplink and downlink transmissions between the AUV and the UAV, subject to water-to-air and airto-water interface impacts; direct transmission scenario (DTS) and retro-reflection scenario (RRS). After providing the channel models and their statistics, the UWSN's outage probability and average bit error rate (BER) are computed. Besides, a tracking procedure is proposed to set up reliable and stable AUV-UAV FSO communications. Through numerical results, it is concluded that the RSS scheme outperforms the DTS one with about 200% (32%) and 80% (17%) better outage probability (average BER) in the uplink and downlink, respectively. It is also shown that the tracking procedure provides on average 480% and 170% improvements in the network's outage probability and average BER, respectively, compared to poorly aligned FSO conditions. The results are verified by applying Monte-Carlo simulations.
