Sensing Traffic Density Combining V2V and V2I Wireless Communications

Sensing Traffic Density Combining V2V and V2I Wireless Communications

Wireless technologies are making the development of new applications and services in vehicular environments possible since they enable mobile communication between vehicles (V2V), as well as communication between vehicles and infrastructure nodes (V2I). Usually, V2V communications are dedicated to the transmission of small messages mainly focused on improving traffic safety. Instead, V2I commun...

Hybrid vehicular communications based on V2V-V2I protocol switching

In this paper, a hybrid communication paradigm for vehicular networking is presented in which connectivity is provided by both existing network infrastructure (e.g., wireless network access points) through a vehicle-to-infrastructure protocol and traditional vehicle-to-vehicle networking. Preexisting infrastructure can provide seamless connectivity, especially when vehicles are sparse or travel...

An Approach to Communications Security for a Communications Data Delivery System for V2V/V2I Safety:

Security Architectures in V2V and V2I Communication

This paper discusses several proposed security architectures to solve the current problems in securing communication between vehicles. Through an analysis of the literature, requirements are derived and discussed, important security architectures are gathered and then compared using the derived requirements. This paper will also shortly discuss vulnerabilities, providing directions for future w...

Comprehensive Vehicular Networking Platform for V2I and V2V Communications within the Walkie-Talkie Project

Communication architectures integrating vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications will be the key of success for the next generation of cars. Nevertheless, the integration of these communication partners in the same platform is a challenging issue because most of the literature is focused on individual parts, such as V2V routing protocols or specific safety ser...
