Abstract: Generation and management of a communication path between a plurality of information processing devices are properly performed.An information processing device is an information processing device equipped with a communication unit and a control unit. The communication unit performs exchange of a signal for generation or updating of a multi-hop communication path using wireless communication with another information processing device. In addition, the control unit performs control to change a metric value included in the signal for generation or updating of the multi-hop communication path based on a state of the information processing device.

Abstract: To suitably perform information transfer, while suppressing interference to other terminal stations, and preventing a reduction of a transmission opportunity of other terminal stations.A terminal station estimates a distance of another terminal station (within a receivable range), from an MCS or RSSI, for example, and controls a transmission power of itself, in accordance with a value weighted with respect to distance. For example, in the case where it is estimated that a number of terminal stations with a far distance has increased, from the value weighted with respect to distance, a transmission power of itself is lowered. As a result of this, transmission by multi-hop is explicitly performed, and it is possible to suppress electric wave interference of a multi-hop destination.
