Abstract: There is provided a wireless communication apparatus and wireless communication method, which can perform information transfer, while suppressing interference to other terminal stations, and preventing a reduction of a transmission opportunity of other terminal stations. By causing the transmission power to be reduced, at the time when a traffic amount to be transmitted and received by itself increases, a terminal station which performs wireless access based on CSMA on a mesh network can suppress interference to other surrounding terminal stations, and can prevent a reduction of a transmission opportunity of other terminal stations. By measuring the number of and sizes of packets to be transmitted and received, it is possible for a terminal station to comprehend the traffic amount to be transmitted and received by itself, and perform a control of the transmission power by this.

Abstract: Communication resources are appropriately used.An information processing device is an information processing device including an acquisition unit and a control unit. Here, the acquisition unit acquires a relative priority of each information processing device in a network built through autonomous wireless communication of a plurality of information processing devices. In addition, the control unit performs control such that a communication resource of the network is allocated based on the priority (a relative priority of each information processing device in the network) acquired by the acquisition unit.

Abstract: Generation and management of a communication path between a plurality of information processing devices are properly performed.An information processing device is equipped with a communication unit and a control unit. The communication unit performs exchange of a signal for generating or updating of a multi-hop communication path using wireless communication with another information processing device. In addition, the control unit performs control for updating path information regarding the communication path set through the exchange of the signal for generating or updating of the multi-hop communication path before the path information is destroyed.
