Abstract:
Random access operation is performed under a communication environment in which a plurality of communication modes having different transmission rate coexist with small overhead. A high-grade communication station spoofs information of a packet length and a rate in a decoding portion so that a value of (packet length)/(rate) corresponds to a duration where the communication is hoped to be stopped. The other station receiving the spoofed information receives the rest of the packet with the designated rate during the interval designated by the value of (packet length)/(rate). In this case, the packet length and the rate are not those of actually transmitted packet so that this packet is discarded.
Abstract:
To efficiently use radio resources.An information processing device is an information processing device that receives a packet. The information processing device is an information processing device that includes a control unit. The control unit included in the information processing device performs control such that reception of a packet is stopped during the reception according to a first condition. The control unit included in the information processing device performs control such that reception of the packet is stopped during the reception and an operation is performed assuming that a carrier sense is an idle state for a time from start of the reception of the packet to stop of the reception of the packet according to a second condition.
Abstract:
An electronic device including circuitry configured to perform control in a manner that a Physical Layer Convergence Protocol (PLCP) header format is selected from a plurality of PLCP header formats; and append the selected PLCP header to a physical layer packet for transmission.
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:
An information processing system includes: a providing unit configured to provide a user with a task for acquiring content related to a specific keyword; an acquisition unit configured to acquire the content acquired by the user according to the task; and a control unit configured to carry out control that notifies the user of use of the acquired content for generating an intelligent information processing unit capable of specifying the relationship between the keyword and the content. The information processing system is capable of collecting learning data by causing an alternate job to be carried out.
Abstract:
In order to solve a problem of an accumulation on the transmission side, a delay on the reception side, and the like at the time of transmission in a communication system such as a wireless LAN system, each communication station in a network transmits a beacon in which information with respect to the network is written and sets a state in which a reception operation is performed during periods of time before and after the transmission of the beacon signal when performing access control not to make communication timing of a packet collide with that of another station by detecting a signal transmitted from another station. With performing such processing, a system can be formed based on minimum level of transmission and reception operation when transmission and reception data does not exist in each communication station in the network, and also a data transfer can be performed with latency as small as possible in a minimum necessary level of transmission and reception operation by making a transition of a transmission and reception state in accordance with a fluctuating volume of transmission and reception data.

There is provided an image processing device including an extraction nit configured to extract an object from an image picked up by use of a certain imaging parameter, a ranging unit configured to acquire distance information indicating a distance between an image pickup unit that has picked up the image and the object that has been imaged, a communication unit having a first transmission function, a second transmission function, and a reception function, and a composition unit configured to combine the object candidate image received by the communication unit in a region of the object included in the second image.
Abstract:
In order to solve problems arising when a communication system such as a wireless LAN is constructed as a decentralized distributed type network without a relationship of control station and controlled stations such as a master station and slave stations, in a wireless communication system composed of a plurality of communication stations without a relationship of control station and controlled stations, respective communication stations transmit beacons with information concerning a network written thereon with each other to construct the network, and it becomes possible to make sophisticated judgment such as communication states of other communication stations by those beacons.
Abstract:
An electronic device includes processing circuitry configured to set a transmitting and receiving operation as active state for a first operating period and determine whether to set the transmitting and receiving operation as a state in which transmission or reception is limited after the first operating period elapses.
