The development of car cloud sensor network isbased on the open sources of Hadoop that support themultidimensional information service studies in this paper. Theoverall system is divided into the layers of physical sensorinformation, communications platform, real-world information, aswell as applications to develop. The function of physical sensorinformation layer builds the connection between in-vehiclenetwork and 3G/4G mobile phone being bridged by the Bluetooth. The physical sensor information is collected into the distributivefile systems on the cloud computing platform by socket providedby communication platform. Finally, a car cloud sensor networkcontained privacy cars and environment regions sensor networksare generated by real-world information layer, and in turnsupport the development of applications based on the car cloudsensor network. The functions of application layer have beencreated to include partner location marking and real-timeenvironment region parameter query at current stage to verifyand validate the functionality of car cloud sensor networkplatform and its services.
