Ranging from large-scale field testing to remote vehicle diagnostics, vehicle performance monitoring and analysis applications rely on the long-term and large-scale collection of in-vehicle sensor data. With wireless vehicular communications, vehicular ad hoc networks provide a promising platform for such applications. In this article, we propose VehicleView to support the large-scale and long-term collection and mining of in-vehicle sensor data. The system architecture and preliminary procedures of VehicleView are proposed based on comprehensive considerations on the common functional, performance, and security requirements of such applications. Supporting various vehicle performance monitoring and analysis applications in a cost-effective, secure, and privacy-preserving way, VehicleView shows great application potential and economic prospects.
