Cellular-based location service to support GeoUnicast communications in vehicular wireless networks

Car to car communication has been getting considerable interest for the last decade, especially in the last few years where market introduction phase is approaching fast. A variety of applications will be enabled thanks to car to car communication. Considerable efforts have been already spent in designing and developing efficient broadcast communication systems to support not only safety applications but also infotainment and traffic efficiency applications and services. This leads in less efforts spent on unicast communication solutions that support not only infotainment applications but also traffic efficiency services. To fill this gap, an advanced location service is proposed in this contribution to enable efficient and reliable unicast communications. This solution mixes between short range communication (over 5.9 GHz) and cellular-based communication. The proposed solution has been validated through extensive simulations using a simulation platform which is compliant to latest related standards.
