Peer-to-Peer Cooperative Driving

In this paper we address database-related issues in the emerging application field of ITS (Intelligent Transportation Systems). In this context we propose and study two cooperative driving scenarios: on-the-fty highway alert scenario and mutual driving group scenario. Vehicles cooperate and coordinate their actions by exchanging information, hence the need for database technologies such as consistency, replication, and query optimization. Technical requirements and suitability of technologies such as wireless and peer-to-peer communication and mobile ad-hoc networks are discussed. We introduce the notion of a peer-dependent query for the application environment.
