Patent attributes
A data transfer path calculation device includes: a travel plan acquisition section that acquires a travel plan composed of routes on which vehicles are estimated to travel and passage times at which the vehicles are estimated to pass through points on the routes; a communication environment acquisition section that, for each of wireless base stations, acquires communication environment information indicating a communication environment for communicating with the corresponding one of the wireless base stations at points; and a transfer path calculation section that searches for a data transfer path based on the travel plan and the communication environment information, the data transfer path being a path through which data sequentially passes, among the vehicles, from an acquisition vehicle through one or more relay vehicles by inter-vehicle communication and from a last relay vehicle among the relay vehicles, the data finally reaching a server via one of the wireless base stations.
