Distributed remote antenna unit with selection‐based of (RoF‐IoT) paradigm: Performance improvement

Abstract

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.

Investigating delay of the media access control protocols for IoT‐RoF using quantum entanglement

“…The 802.11 Radio over fibre (RoF) architecture's primary strength is that it brings together the capacity as well as transparency of optical fibre networks with the adaptability, simplicity, and portability of wireless networks. Furthermore, because RAUs may be located closer to mobile stations, coverage can be improved, air propagation can be constrained, and transmission power can be reduced [1,2].…”
