A Method for Improving Data Delivery Efficiency in Delay Tolerant VANET with Scheduled Routes of Cars

IVCS 2010 : 2nd IEEE International Intelligent Vehicular Communications System Workshop , Jan 9-12, 2010 , Las Vegas , NV, USAIn vehicular ad hoc networks (VANETs), delivering messages to a specific location is difficult due to the high mobility of vehicles. In this paper, we propose a method for efficient message delivery in VANETs utilizing the route information in car navigation systems. In the proposed method, each car periodically exchanges the information on its current position and scheduled route in the car navigation system with neighboring cars within radio range. By referring to the exchanged information, each car forwards messages to the neighboring car that will most closely approach the destination. Through simulations, we confirm that the proposed method achieves a better delivery rate with low bandwidth usage than a geocast-based method and epidemic routing
