Conventional routing protocols are not applicable for vehicular Ad-hoc NETworks (VANETs) due their specific network characteristics i.e. frequent network topology and frequent disconnections. Data Fusion techniques are combined with localization techniques to provide robust localization information. In Location-aware VANET applications the location of the vehicle information is displayed on the map by installing GPS receivers on the OBU to provide driver assistance in critical positions. Geographic forwarding forwards packets based on their geographic location. While exploiting data, the time to reach destination requires estimation.
