Vehicular ad hoc networks support a wide range of promising applications including vehicular sensing networks, which enable vehicles to cooperatively collect and transmit the aggregated traffic data for the purpose of traffic monitoring. The reported literatures mainly focus on how to achieve the data aggregation in dynamic vehicular environment while the security issue especially on the authenticity...
Providing vehicles' position is essential in VANETs. Currently, GPS positioning is widely used, but the accuracy is not adequate for emerging safety applications. In order to provide accurate positioning, this paper proposes RF-GPS, a RFID-assisted localization system that reliably supports lane-level position accuracy. It improves accuracy of the GPS system by employing a DGPS-like concept. It also...
Wireless position is one of the most important research fields in VANET application. It has certain technical restrictions to realize the accurate position between vehicle using wireless communication network., but it can realize approximate position between vehicles in local area, and can satisfy the requirement of vehicle active safe technologies such as collision warning for location precision...
