As a vehicle reenters the atmosphere or travels at hypersonic speeds within it, a bow shock forms around the leading edge of the vehicle. The air is superheated as it passes through the shock wave and becomes ionized. This plasma layer prevents the transmission of radio frequency communications to or from the vehicle, causing what is know as communications blackout. In this paper, we present re...

Inter-vehicle communications, in the context of Intelligent Transportation Systems, will probably bring a significant improvement in both traffic safety and efficiency. In order to evaluate in what measure this is true, traffic simulations that take into account the communications between vehicles are needed. In this paper, we propose an agent-based architecture, in which the simulation and man...

Abstract. As modern vehicles are sophisticated IoT devices with intelligence, capable of connecting to external infrastructure and utilizing vehicle-to-everything (V2X) communications, communications need be secured so that cyberattacks do not reach their destination. In addition, the various organs car (sensors, controls) can have weaknesses lead accidents or potential fatalities. Automakers a...

We present experimental results for an active control Intersection Collision Avoidance (ICA) system implemented on modified Lexus IS250 test vehicles. The system utilizes vehicle-to-vehicle (V2V) Dedicated Short-Range Communications (DSRC) to share safety critical state information, allowing for distributed implementation of our provably safe algorithms. Safety is achieved in potential collisio...

Modern vehicles are complex cyber-physical systems where communication protocols designed for physically isolated networks now employed to connect Internet-enabled devices. This paper presents an overview of wireless automotive technologies and the Interference Rejection Combining Approach in Vehicle Communication with aim identifying strong candidates future in-vehicle inter-vehicle applicatio...

In this article, we develop a decentralized resource allocation mechanism for vehicle-to-vehicle (V2V) communication systems based on deep reinforcement learning. Each V2V link is considered as an agent, making its own decisions to find optimal sub-band and power level for transmission. Since the proposed method is decentralized, the global information is not required for each agent to make its...
