TL;DR: Initial designs and results of a small-scale prototype of a vehicle to vehicle communication system using light fidelity (Li-Fi) technology, a new technology that was developed in the last few years, which still needs more investigations on its sustainability for outdoor vehicular networks.
Abstract: In this paper, we present initial designs and results of a small-scale prototype of a vehicle to vehicle communication system using light fidelity (Li-Fi) technology, a new technology that was developed in the last few years, which still needs more investigations on its sustainability for outdoor vehicular networks. Vehicle to vehicle communication is the most effective solution that has been used in order to reduce vehicles' accidents. The proposed use of Li-Fi technology in this paper comprises mainly light-emitting diode (LED) bulbs as means of connectivity by sending data through light spectrum as an optical wireless medium for signal propagation. In fact, the usage of LED eliminates the need of complex wireless networks and protocols. Several case studies mimicking the vehicle to vehicle communication are explored in this work. Both numerical simulations using Proteous package and experimental results are also presented, which agree quite well.

TL;DR: An overview of the system architecture is given and the communication, signal processing, and decision-making sub-systems are described in detail to demonstrate the system’s performance and operation according to the rules and requirements of the competition.
Abstract: In this paper, we present the cooperative driving system developed by the Chalmers car team for the grand cooperative driving challenge 2016. This paper gives an overview of the system architecture and describes in detail the communication, signal processing, and decision-making sub-systems. Experimental results demonstrate the system’s performance and operation according to the rules and requirements of the competition.

TL;DR: A fuzzy-assisted social-based routing (FAST) protocol that takes the advantage of social behaviour of humans on the road to make optimal and secure routing decisions and results show that the FAST performs best in terms of packet delivery ratio.
Abstract: In the autonomous environment of Vehicular Ad hoc NETwork (VANET), vehicles randomly move with high speed and rely on each other for successful data transmission process. The routing can be difficult or impossible to predict in such intermittent vehicles connectivity and highly dynamic topology. The existing routing solutions do not consider the knowledge that behaviour patterns exist in real-time urban vehicular networks. In this article, we propose a fuzzy-assisted social-based routing (FAST) protocol that takes the advantage of social behaviour of humans on the road to make optimal and secure routing decisions. FAST uses prior global knowledge of real-time vehicular traffic for packet routing from the source to the destination. In FAST, fuzzy inference system leverages friendship mechanism to make critical decisions at intersections which is based on prior global knowledge of real-time vehicular traffic information. The simulation results in urban vehicular environment for with and without obstacles scenario show that the FAST performs best in terms of packet delivery ratio with upto 32% increase, average delay 80% decrease, and hops count 50% decrease compared to the state of the art VANET routing solutions.

TL;DR: The paper presents the current mobile wireless communication applications and standards, the various DSRC standards that have been proposed, their potential use in ITS applications, their envisioned implementation benefits, and the remaining research needs.
Abstract: In efforts to reduce traffic accidents and improve the efficient utilization of existing transportation networks, increasing attention is being given to the use of wireless communications between vehicles and roadside equipment to develop new intelligent transportation system (ITS) applications that can help improve the safety of transportation networks and reduce urban congestion. Of particular interest for the development of such applications are the currently proposed dedicated short-range communication (DSRC) wireless standards. This paper aims to provide transportation researchers and engineers with an introduction to these standards. The paper presents the current mobile wireless communication applications and standards, the various DSRC standards that have been proposed, their potential use in ITS applications, their envisioned implementation benefits, and the remaining research needs.

TL;DR: An inter-vehicle communication system, operating on android smart phone by using Wi-Fi, that can be easily installed in any android devices and is more suitable for vehicular ad-hoc network (VANET) scenario than other systems.
Abstract: Although IEEE has already announced 802.11p standard for wireless access in vehicular environment (WAVE) to support Intelligent Transportation System (ITS) communication, it requires additional 802.11p hardware equipment to allow vehicles communicating with others using 802.11p. Therefore, in this paper, we propose an inter-vehicle communication system, operating on android smart phone by using Wi-Fi. To substitute 802.11p onboard unit (OBU) before its widespread use on modern vehicles. Experiment results shows that our system can not only be easily installed in any android devices (android 2.3 and above) but is also more suitable for vehicular ad-hoc network (VANET) scenario than other systems.
