Abstract: To cause a specific device to stay in a specific location. An information processing apparatus includes a control unit. The control unit in the information processing apparatus performs control that transmits a stay request to request a stay in a specific location to a first information processing apparatus included in a plurality of information processing apparatuses in a network in which the plurality of information processing apparatuses perform one-to-one wireless communication to be connected to each other. In addition, the control unit in the information processing apparatus performs control that gives an incentive to the first information processing apparatus under a condition that the first information processing apparatus stays in the specific location.

Abstract: An information processing apparatus including a control unit configured to perform control to detect leaving of a user from the information processing apparatus and transmit at least part of context information exchanged with the user until then to another apparatus. The information processing apparatus can improve user-friendliness by detecting behavior of a user and linking data with each other in advance between equipment to be operated by the user.

Abstract: Information on the belongings of a nearby-present person is easily acquired. An information processing apparatus comprises a reception unit and a control unit. Herein, the reception unit is directed for receiving belongings information of the user of other information processing apparatus transmitted from the other information processing apparatus by use of wireless communication. Further, the control unit is directed for causing the received belongings information to be output and controlling evaluation information on the belongings information to be transmitted to the other information processing apparatus by use of wireless communication on the basis of a user operation for the belongings information.

Abstract: A network system includes at least first and second communication devices connected in a network. The first communication device includes an inquiry device for inquiring the attributes of the second communication device to the second communication device via the network. The second communication device includes an attribute holding device for holding the attributes and a search device for searching for the attributes held in the attribute holding device in response to the inquiry and responds back with the search result to the inquiry device. The attribute holding device and the search device operate in a data link layer.

Abstract: In a WUSB communication environment in which isochronous transfer cannot be used, priority communication is performed in units of devices. A WUSB host manages assigning of a band of reserved one or more MASs in a superframe by using a device information management table, in which device information entries each describing, in a bitmap format, a MAS for which a transaction can be executed are each provided for a WUSB device. The WUSB host assigns at least some of the reserved one or more MASs only to a particular WUSB device. Only a WUSB device marked in a corresponding device information entry serves as a target of transaction scheduling.

Abstract: The communication device according to the present invention includes a communication condition detection unit that detects communication conditions with regard to communication with other communication devices, a link adaptation decision-making unit that makes a decision as to whether or not link adaptation needs to be executed in correspondence to the communication conditions, a link adaptation parameter selection unit that selects a link adaptation parameter to be used for the link adaptation when the link adaptation is judged to be necessary, a transfer rate decision-making unit that makes an advance decision as to whether or not the data transfer rate is to become, lower compared to the pre-link adaptation state if the link adaptation is executed based upon the selected link adaptation parameter and a link adaptation unit that executes the link adaptation based upon the selected link adaptation parameter if the data transfer rate is judged not to become lower.
