Abstract: A packet loss is specified in a communication device for transmitting a communication packet to a destination device via a route and receiving a delivery confirmation packet of the communication packet from the destination device. Sequence information of the communication packet for a communication flow is acquired. A correspondence relationship between a transmission order of the communication packet and the sequence information of the communication packet for each route is stored as transmission order correspondence information. Delivery confirmation information indicating a delivery state of the communication packet is acquired. It is determined whether the packet loss has occurred based on the transmission order correspondence information and the delivery confirmation information.

Abstract: A target communication line defined as a congestion determination target and a client that transmits an ACK signal to a communication partner in a case where a signal is received from the communication partner are relayed to each other. It is determined whether a congestion occurs on a target communication line. A communication of the ACK signal is limited by a capture process that captures the signal communicated by the client in a case where determining that the congestion occurs on the target communication line.

Abstract: A vehicle communication device for use in a vehicle includes a data acquisition unit for acquiring captured images as travel data; a data generator for generating transmission data from the travel data for transmission to a data center; and a data transmitter transmitting the transmission data generated by the data generator to the data center. When there is a plurality of different travel data types, the data generator can increase the priority of any of the travel data types based on a data center necessity level, and prioritize the transmission of the transmission data generated from prioritized travel data.

Abstract: A data collection system includes: a communication terminal in each vehicle having a storage processor storing specific sensing information in a storage device and a vehicle-side communication unit; and a data center including a data center-side communication unit and a data center-side storage. The vehicle-side communication unit sequentially transmits vehicle information including a vehicle position to the data center. The data center-side communication unit transmits a transmission request of object information as the specific sensing information to an object vehicle, which is one of the vehicles approximately at a traveling position specified based on the vehicle position. The vehicle-side communication unit transmits the object information to the data center. When the data center-side communication unit receives the object information from a part of object vehicles, the data center-side communication unit transmits a deletion request for requesting to delete the object information to a remaining part of the object vehicles.

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.

Abstract: In a wireless communication apparatus, data transmitted from at least one wireless transmitter is received by direct wireless communication, and its wireless reception condition is detected. Relation reference information setting two or more relations between the wireless reception condition on a reception of transmitted data and location information of the transmitter is stored. Relative distance information of a relative distance between the transmitter and the apparatus is measured. Relation information indicating a relation between the wireless reception conditions and the relative distance information is generated. A relation between the location information and the relative distance information is determined by comparing the relation reference information and the relation information. A current location of the apparatus is determined on the basis of the relation between the location information and the relative distance information and a current wireless reception condition.

Abstract: By a communication device, a line delay time estimation method, a non-transitory computer-readable storage medium storing a line delay time estimation program, a communication packet is accumulated, a data amount of the communication packet is monitored, and a residence time, which is a duration and for which the communication packet remains in a transmission buffer, is estimated as an upstream buffer delay time from the communication device to a counterpart device.
