Abstract: The intent of VANET (vehicular ad hoc network) is to allow efficient information dissemination aimed at the safety and comfort of passengers and drivers and to safeguard them from risk. Some potential applications that help travellers are driver assistance, collision detection, internet access, map location and so on. The most precarious one is the collision detection and avoidance. A collision happens when the distance between neighbouring vehicles rapidly decreases. Thus, a precise and accurate knowledge about the distance between vehicles has to be determined to allow a robust collision avoidance service. Hence, in this paper a Range Frequency based Distance Computation (RFDC) technique is proposed to provide distance estimation between every vehicle that approximates to the actual distance. The performance of the proposed approach is analysed in terms of delay, energy utilised, accuracy and received signal strength and compared with the existing MDS (multi-beacon signal).
Keywords: VANET; distance; range frequency; received signal strength.
