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.

Abstract: A ledger management system includes multiple ledger management devices communicably connected to each other. The ledger management devices have a same distributed ledger. Each ledger management device includes the distributed ledger, an agreement determination unit, and a ledger storage unit. The distributed ledger stores ledger information, including specific information specific to a previous ledger information and present vehicle information obtained from a vehicle, that is generated by one of the ledger management devices. The agreement determination unit determines whether the ledger information generated by the one of the ledger management devices satisfies an agreement rule. The ledger storage unit stores the ledger information in the distributed ledger when the ledger information satisfies the agreement rule, and does not store the ledger information in the distributed ledger when the ledger information does not satisfy the agreement rule.

Abstract: In a wireless communication system, a mobile communication apparatus judges the reception quality available at its current position for direct reception of information transmitted from a fixed wireless station, with the judgement based upon the current position and upon a reception quality map expressing a relationship between reception positions and corresponding reception quality values. If the reception quality at the current position is judged to be sufficient, direct reception is executed, while otherwise, a limitation is placed upon such direct reception, for example by postponing the direct reception until reaching a position at which the reception quality will be sufficient.
