On the Performance Analysis of V2N Mixed RF and Hybrid FSO/RF Communication System

Abstract

Vehicular communications allow vehicles to connect with other vehicles and network infrastructures in order to facilitate the transfer of real-time information and dependable transportation. This paper proposes a system that connects vehicles to the network (base station) in two phases using transceiversequipped roadside infrastructures, such as signboards, traffic lights, and street lights, as intermediary relay nodes. In the first phase, the information transfer occurs from vehicles to infrastructure using a radio-frequency (RF) link. The second phase includes establishing communication from the infrastructure to the base station using hybrid free-space optics (FSO)/RF link. In modeling the FSO link, we consider factors like atmospheric attenuation, pointing errors, and atmospheric turbulence-induced fading, which can affect FSO performance. For this set-up, we derive the accurate expressions for the outage probability, system throughput, average symbol error rate, and average end-toend delay. Numerical results corroborate the dependency of the time allocation factor α for the vehicle-to-infrastructure link on the vehicle transmit power. Furthermore, the results elucidate the impact of the length of the transmitted packet and FSO link distance on average end-to-end delay performance. The increase in distance between infrastructure and base station can be compensated by reducing the length of packets to achieve desirable delay performance.

A Survey on Video Streaming for Next-Generation Vehicular Networks

“…In the realm of transportation and automotive technology, researchers have proposed various applications and conducted performance analyses of V2N communication. In a study led by Sandeep et al [37], the authors introduced a relay architecture for V2N, outlining a system that establishes a connection between vehicles and a base station through a two-phase process. This entails using transceiver-equipped roadside infrastructures, including signboards, streetlights, and traffic lights as intermediate relay nodes.…”

“…They employed maximal ratio combining to merge signals from both transmission channels, mitigating channel fading. Sandeep et al [37] employed roadside infrastructure as a relay node to connect vehicles to base stations, utilizing a hybrid FSOC/RF technology for communication. Lu et al [275] implemented an FSOC-THz link, achieving a high total data rate of 86.112 Gbps with a bit error rate < 3.8 × 10 −3 and an error vector magnitude <10%.…”

“…Free space optical (FSO) communication has attracted great attention due to its advantages over radio frequency (RF) communication, such as very high bandwidth, heavily secured links, robustness to electromagnetic interference, and ease of deployment [6], [7], [8]. In addition, the combination of FSO communication and satellite technology can achieve ubiquitous coverage and high transmission capacity which can meet the future requirements [9], [10].…”

A comprehensive review of performance analysis of RF-FSO hybrid communication systems

“…The data rate, bandwidth, and transmission range of conventional wireless communication technologies like radio frequency (RF) and microwave are constrained [1]. Free-space optical (FSO) communication, on the other hand, can provide high data rates, large bandwidth and system capacity, licensed spectrum, and anti-electromagnetic interference [1][2][3][4][5] but it is sensitive to atmospheric conditions such as atmospheric turbulence, pointing error, and atmospheric attenuation and has a limited transmission range [1][2][3][4][5][6][7][8].…”
