V-PADA: Vehicle-Platoon-Aware Data Access in VANETs

The high mobility of vehicles and the unreliable wireless communication significantly degrade the performance of data access in Vehicular Ad hoc NETworks (VANETs). To address this problem, the authors propose a novel vehicle-platoon-aware data access solution called V-PADA. In V-PADA, vehicles contribute part of their buffers to replicate data for others in the same platoon and share data with them. When a vehicle leaves the platoon, it prefetches interested data and transfers its buffered data to other vehicles in advance so that they can still access the data after it leaves.
