Provisional chapter Distributed Trust and Reputation Mechanisms for Vehicular Ad-Hoc Networks

The parallel evolution of automotive industry and anywhere/anytime communication mechanisms has defined a revolutionary moment for intelligent driving concept. Vehicular Ad Hoc Networks, also known as VANETs, exploit the capability of wireless communications protocols to confidently disseminate sensitive information among peers, restricted to a particular geographic area, as well as the advanced safety-assets, on road sensors and sophisticated driving-assistance features of top-generation vehicles. Such a complement are not only oriented to offer a more pleasant in-car experience for driver and passengers, but also are intended to introduce autonomous and efficient ways to prevent hazardous situations on roads. Then, VANETs deployment should follow a primary task based on reliable message handling for sharing traffic conditions, weather variables, driving assistance, navigation support, entertainment content multicasting and even spurious notifications [1], [2].
