摘要： Provided is a communication terminal device that reduces, in a network using a power line, the percentage of bands consumed for transmission of control packets in the bands consumed for all the communication, so as to ensure transmission of data intended to be transmitted. A PLC terminal F701 connected to the network of power line communication transmits, when having determined that the terminal does not receive from the network a beacon for a predetermined period of time, a beacon request packet to the network, using a modulation method having the lowest communication speed among the modulation methods that can be used in the network.

摘要： A source apparatus writes, in a route request packet, the number of routes requested by the source apparatus. When a relay apparatus receives a route request packet for the first time, the relay apparatus determines a waiting time period, based on a route evaluation value that indicates a state of a route through which the route request packet has passed, and starts a timer. The relay apparatus selects route request packets having as high route evaluation values as possible, among route request packets that have been received until the timer expires, the number of route request packets to be selected being equal to the number of routes requested by the source apparatus, and then broadcasts the selected route request packets.

摘要： There is provided a communication apparatus which, in an ad-hoc network, when receiving control packets from a plurality of terminals, can determine whether or not there is a collision among the control packets, and, based on the determination, can be prevented from continuing to be out of the network due to a collision among the control packets transmitted from the plurality of terminals. In the communication terminal, a communication section receives a control packet which periodically comes up on a communication path. When the communication apparatus receives a plurality of control packets which are defective in at least payload portions thereof within a predetermined time period, if a control section determines that source addresses included in header portions of the control packets which are defective in the payload portions thereof include a source address which is not identical to the other source addresses, the control section determines that the control packets are transmitted from a plurality of terminals and collide with each other.

摘要： Each of PLC modems 11 through 14 that perform communication using a PLC network 1 manages a priority management table that contains, for each of a plurality of data exchanged using a common transmission line, (i) a main priority (original), (ii) a main priority (changed), and (iii) a sub-priority. For example, when the PLC modem 11 detects congestion, the PLC modem 11 searches its priority management table for a stream that has the same main priority (original) as and a lower sub-priority than data transmitted by the PLC modem 11. The PLC modem 11 then transmits, to the PLC modem that transmits the stream found as a result of the above search, a notification signal notifying that the data transmitted by the PLC modem 11 has a high sub-priority.
