This paper describes a cooperative MANET protocol dedicated to intelligent transportation systems and its new experiment results in mobile scenarios. The protocol is named CIVIC (Communication Inter Véhicule Intelligente et Coopérative). It is an auto-configuration inter-vehicle communication protocol, which supports ad-hoc and infrastructure networks, contains reactive and proactive routing components, and adapts different wireless standards. It is also a location-based and context-aware protocol reacting to vehicle status, road traffic, and geographic environment. The CIVIC protocol has been implemented on the LiveNode sensor developed by our laboratory. The new experiments of CIVIC protocol are carried out on PAVIN platform (Plate-forme d'Auvergne pour Véhicules Intelligents) supported by the TIMS (Technologies de l'Information de la Mobilité et de la Sûreté) research federation. These experiments demonstrate the feasibility and reliability of CIVIC in mobility scenarios. In addition, an application project named MobiPlus will be introduced.
