Automotive Networking And Applications

The articles in this special section focus on automotive engineering networking and applications. In this 20th issue of the Automotive Networking and Applications Series, we are pleased to present two articles that address the following issues: distributed automotive security architecture based on blockchain (BC) and road traffic density estimation using mobile sensors such as smartphones. Vehicles are increasingly connected to the Internet, the roadside infrastructure, and other vehicles, thus enabling services in convenience, traffic efficiency, and driving safety. This connectivity, however, exposes vehicles to security and privacy threats such as remote hijacking of vehicles or location tracking of vehicle users, among others, while existing methods for security and privacy tend to experience challenges in terms of scalability and performance.
