Wireless in-vehicle network technologies hold the potential to support a multitude of new and innovative approaches based on intra-vehicle, vehicle-to-vehicle, and vehicle-to-roadside networking of in-vehicle electronic systems. Inter- and Intra-Vehicle Communications provides details of the current state-of-the-art of wireless communication technology within as well as between vehicles. Addressing the Medium Access Control layer protocols, this book reviews security issues associated with vehicle communication, examines protocols used to transfer data, and explores the role of sensors used inside and outside a vehicle as a mechanism for developing smart automobiles.
