“…We mentioned in the introduction that there are studies in the literature on wide-angle receivers for vehicles that are not within each other's LOS. One of these studies is the multidirectional V2V VLC system mentioned in [17], which was used to increase the receiver's FOV on three-lane roads. According to the results of [17], the communication efficiency is enhanced when manually adjusting the receiver's FOV by changing the receiver's photodiode type according to the distance between the transmitter and receiver.…”

The results of our study revealed the effectiveness of a receiver design that is more practical and easier to adapt to real life, eliminating the need to manually change the FOV of the receiver by directing the receiver in the direction of the most intense light.…”

“…Our receiver turned itself 29 • towards the most intense light and achieved a 17% increase in the received light intensity. In addition, when the three-lane road in [17] increases to four lanes, the FOV angles of the receivers need to be adjusted, and the azimuth angles between the receivers facing in different directions need to be manually adjusted again. Our receiver design works with the same efficiency and aligns automatically with the direction of the highest-intensity light even if the number of road lanes increases.…”

“…A multi-directional VLC system is a promising method for acquiring data from vehicles in different lanes on multi-lane roads. It uses three PDs at the receiver side oriented in different directions [17,18]. Differently oriented PDs can increase the field of view (FOV) of the receiver, which can be beneficial at intersection points.…”

In this paper, a novel method is demonstrated to sustain vehicle-to-vehicle (V2V) communication on curvy roads via the arrangement of the lateral position of a self-angle-adjustable mirror–reflective road sign (SAAMRS) and light-direction-sensing wide-angle complementary photodiodes (CPDs). Visible light communication (VLC) between vehicles attracts attention as a complementary technology to radio-frequency-based (RF-based) communication technologies due to its wide, license-free spectrum and immunity to interferences. However, V2V VLC may be interrupted on curvy roads due to the limited field of view (FOV) of the receiver or the line of sight (LOS) being interrupted. To solve this problem, an experiment was developed using an SAAMRS along with wide-angle light-direction-sensing CPDs that used a precise peak detection (PPD) method to sustain communication between vehicles in dynamic environments by rerouting the incident light with the highest signal intensity level to the receiver vehicle on curvy roads. We also used real images of curvy roads simulated as polynomials to calculate the necessary rotation angles for the SAAMRS and regions where communication exist. Our experimental results overlapped almost completely with our simulations, with small errors of approximately 4.8% and 4.4% for the SAAMRS angle and communication region, respectively.

“…Nevertheless, they cannot cover all directions, and the receiver still has a limited view. To overcome these limitations, a non-imaging angle diversity receiver [15], [16] was proposed as a potential solution. It consists of different detection branches, each with its own optical detector, orientated at specific angles, allowing reception from various angles.…”

Vehicular Visible light communication (VLC) technology has recently attracted much interest from researchers and scientists. This technology enables connectivity between vehicles and infrastructures along the road by using vehicles' headlights and taillights as wireless transmitters. The reliability of vehicleto-vehicle (V2V) VLC systems is affected by several factors, such as car mobility, optics system design, and visibility conditions, where the first two have the most impact on the VLC system performance. This paper, therefore, focuses on the relative positions of the cars and the design of the optics, especially on the receiving end, which has been proposed with the use of a polar detector instead of the rectangular detectors commonly used in the literature. We investigate the achievable gain compared to the conventional detector for different vehicle locations, utilizing a professional optical system design and ray tracing approach. Then, to improve the performance, we introduce the utilization of an imaging receiver by integrating the polar detector with different optical commercial lens combinations, such as Fresnel and Aspherical lenses. To further improve the V2V system performance, we propose a novel optical lens combination design by integrating double-convex lens with half-Plano-concave lens, which allows the correction of more optical aberrations, such as chromatic and spherical aberration. Utilizing the non-sequential ray tracing tools, we designed these VLC systems and perform a realistic channel modeling study considering the typical 3D CAD models of vehicles and roads as well as the possibility of horizontal and vertical movement between the vehicles. Based on the channel impulse responses (CIRs) obtained from the ray tracing simulations, we analyzed the performance of V2V VLC systems with all lens combinations at different vehicle positions on the road. We further investigated the impact of different system parameters on the overall V2V system performance, such as receiver diameter and bandwidth. The obtained results demonstrated that with a carefully chosen system and lens parameters, the proposed system design of lens combination provides an enhancement of up to 7 dB in total received power compared to the case without a lens. Our results also revealed that the proposed system design outperforms the benchmark ones for all lateral displacements and longitudinal distances.INDEX TERMS Vehicular communications, visible light communication, optical lens combination, polar detectors.
