Data Transmission Plan Adaptation for Connected Vehicles
MetadataShow full item record
Connected vehicles can nowadays be equipped with multiple network interfaces to access the Internet via a number of networks. Given a network availability map and a vehicle’s route, a joint time-network selection plan could attempt to schedule delay-tolerant data transmission efficiently. Since the networks presence and available capacities change rapidly and in an unforeseen manner (because of changing conditions due the uncertainty in car movement, data transmission needs and network characteristics), the efficiency of such a planning may be severely compromised. Consequently, mechanisms that determine the deviation from the foreseen conditions are derived in this paper, which modify the transmission plan depending on the type of deviation observed. Simulation results show that the proposed mechanisms help maintain the benefits of a joint time-network planning under changing conditions.
