Abstract
A communication controller is provided for controlling a wireless communication device disposed in a vehicle to transport data to a target device. The communication controller includes a searcher, a cost computer, a path determiner, and a communication control section. The searcher detects the current position of the vehicle, determines a travel plan of the vehicle, and searches for one or more transport paths for transporting data to the target device. The cost computer calculates a transport cost for each of the transport paths. The path determiner determines the lowest transport cost, selects the transport path, and determines the transmission conditions. The communication control section transmits the data to the target device when the transmission conditions are satisfied.

A communication controller for controlling a wireless communication device disposed or carried in a movable body to transport data to or from a target device, the communication controller comprising:
- a searcher configured to search for transport path information for one or more transport paths for transporting the data between the wireless communication device and the target device, wherein the transport path information includes communication state requirements, which are either of (i) conditions for a communication position, which is the position at which data communication is performed, or (ii) conditions for a communication state that varies according to the communication position, for the wireless communication device;
- a cost computer configured to compute a transport cost for transportation of the data between the wireless communication device and the target device for each of the transport path information for the one or more transport paths, wherein the transport cost is computed based on a travel parameter and a communication parameter, the travel parameter regarding includes at least one of a duration or distance of a travel of the movable body until the communication state requirements are satisfied, and the communication parameter regarding communication of the data by the wireless communication device when the communication state requirements are satisfied;
- a path determiner configured to determine the transport path information that defines the transport path for an actual transport of the data based on the transport cost computed by the cost computer for each of the transport path information;
- and
- a communication control section configured to control the wireless communication device to perform communication of the data when the communication state requirements that are included in the transport path information determined by the path determiner are satisfied and keep the data in a memory mean without communicating the data otherwise, wherein
