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 exchanges 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 such that, when there is path information regarding a communication path to another information processing device in a case in which the signal for generation or updating of a multi-hop communication path is transmitted to the other information processing device, the signal is transmitted to the other information processing device in unicast, and the signal is transmitted in broadcast.

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: 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.

Abstract: A vertical-cavity surface-emitting (VCSEL) device has a layer structure including a top DBR mirror, an active layer, a current confinement oxide layer, and a bottom DBR mirror, the layer structure being configured as a mesa post. The current confinement oxide layer has a central current injection area and a peripheral current blocking area oxidized from the sidewall of the mesa post. The mesa post has a substantially square cross-sectional shape, thereby allowing an oxidation heat treatment to configure a substantially circular current injection area in the current-confinement oxide layer.
