“…The transmission techniques commonly used in VLC systems include the User Datagram Protocol (UDP) [29,30], and on/off keying (OOK) [31,32], using an arbitrary waveform generator or universal software radio peripheral (USRP) devices (National Instruments, Austin, TX, USA). In our paper, V2V VLC is achieved using OOK, where an LED is employed as the light source for data transmission, and data are carried when the LED is either on or off.…”

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.

“…A growing number of research works on the handover in VLC and wireless mobile networks have been reported in the literature, which are mostly focused on proposing schemes to achieve a smooth handover with decreasing data rate fluctuation and increasing transmission bandwidth [10], [12]. In addition, in [8], [16] and [17], we proposed and evaluated new architectural designs, aiming at handover delay decrement and VLC network throughput increment.…”

“…Note that to the best of authors knowledge this paper is the first to evaluate T hod in a V-VLC network with two dimensions movements, considering possible scenarios where an AGV experiences link failure during handover. Previously, in [16] and [8], we initially proposed the idea of using link aggregation on top of multiple VLC clients for AGV and frequency division for neighboring LAPs and their corresponding LCs. In addition, we analyzed an interface bonding scheme using only two different primary interfaces and evaluated T hod for the AGV with a linear movement [8], [16].…”

“…Additionally, mobile terminals in the factory will face frequent handovers [7,8] between high-density access points. In order to ensure that the voice and data communications are not interrupted in the mobile scenario, the handover needs to be performed so that the user can access the LAP which can provide better communication service quality [9][10][11][12]. In this case, the handover cannot be simply based on the method under the plane receiver, but should combine the characteristics of the cubic receiver under study.…”

Visible light communication (VLC) has the advantages of rich spectrum resources, endogenous safety and anti-electromagnetic interference, so the application of VLC to the Industrial Internet of Things is one of its current development directions. Due to the limited coverage of light emitting diodes (LEDs), dense placement is often required in industrial manufacturing scenarios. However, mobile users will face frequent handover between these LEDs, and reliable reception of signals on mobile terminals requires receivers with a large detection area. In this paper, we used a cubic receiver to increase the detection area, which is more conducive to signal reception than a single photo-detector plane receiver. Then we studied the handover scheme for a cubic receiver to ensure the performance of the communication link. We also rotated the receiver to further improve signal quality and obtain the optimal rotation angles using a genetic algorithm with low complexity. The results show that a cubic receiver has a better received signal quality than a plane receiver, and rotation can enhance the signal quality more. In addition, it can be seen that the handover for the cubic receiver depends not only on the distance, but also on its structure, angle and position. Considering these factors jointly when performing a handover, users can connect to LEDs, which provide the best quality of service, and system communication performance can be improved.
