“…Vehicular visible light communication (V-VLC) [46,[69][70][71][72][73] is often described as supplementary or "sister" technology to planned 5G [31]. There is also a concept of social internet of vehicles (SIOV) [74][75][76], which is based on LTE/4G network, consisted of multiple road side units (RSU) based on eNodeB base stations and on-board units (OBU) with LTE/4G capabilities.…”

In this paper, our first attempt at visible light communication system, based on software defined radio (SDR) and implemented in LabVIEW is introduced. This paper mainly focuses on two most commonly used types of LED lights, ceiling lights and LED car lamps/tail-lights. The primary focus of this study is to determine the basic parameters of real implementation of visible light communication (VLC) system, such as transmit speed, communication errors (bit-error ratio, error vector magnitude, energy per bit to noise power spectral density ratio) and highest reachable distance. This work focuses on testing various multistate quadrature amplitude modulation (M-QAM). We have used Skoda Octavia III tail-light and Phillips indoor ceiling light as transmitters and SI PIN Thorlabs photodetector as receiver. Testing method for each light was different. When testing ceiling light, we have focused on reachable distance for each M-QAM variant. On the other side, Octavia tail-light was tested in variable nature conditions (such as thermal turbulence, rain, fog) simulated in special testing box. This work will present our solution, measured parameters and possible weak spots, which will be adjusted in the future.

“…Most Czech public institutions deploy exactly this type-testing it is the most logical step, as we can use every ceiling light at our university as transmitters. Figure 1 describes different ways of V2X communication [30,45,46], mentioned earlier. V2V is a system, which enables car to communicate with each other.…”

For indoor visible light communication (VLC), much work has been done when the noise is independent of the input signal. However, less effort is made when the VLC system suffers from the input-dependent noise. Considering the input-dependent noise, this paper focuses on the performance analysis and optimization for indoor VLC system. The Lambertian emission-based channel model and on-off keying modulation are employed. According to the system model, the bit error rate (BER) with a closed-form expression is derived. To enhance the system performance, an optimization problem that minimizes the BER by tilting the receiver plane is formulated. By solving the problem, the optimal tilting angle of the receiver is obtained. Simulation results verify the derived expression of BER. It is also shown that the BER is strongly affected by the input-dependent noise. Moreover, the optimal tilting angles for the receiver at any position are obtained, which can provide some insights for practical system design.

“…The Device-To-Device Communication (D2D) is one of the communication models that is implemented in IoT ecosystem which applies direct connection between devices to exchange data in a distributed fashion without traversing a core network. D2D communication is an emerging research phenomenon which benefits ultra-low latency [3] in communication due to a shorter signal traversal path. D2D communication architecture consists of heterogenous computing devices with different capabilities connected together [4], [5].…”

Device-to-device communication is popular research trend that presents ubiquitous information exchange on the Internet of Things. D2D communication provides data exchange without transiting to a base station using direct communication between two devices. For such environment, successful delivery of data to the receiver is needed. In this paper, we suggest a Bee-Inspired Routing Algorithm (BIRA) for D2D communication in IoT exploits the multiple interfaces of a "thing" in IoT having different wireless standards. BIRA is on demand routing algorithm simulates the bee's foraging behavior model to find optimal path between source and destination for multi-hop communication. The performance of BIRA is assessed through extensive simulations that concludes BIRA realizes better packet delivery ratio as well as it performs lower average end-to-end delay in different traffic load compared to the conventional AODV protocol. Also, BIRA achieves least energy consumption than AODV and increases network lifetime.
