摘要： A technique is disclosed, by which it is possible to achieve the reduction of power consumption of each wireless node and to perform efficient access control in wireless communication system. According to this technique, a given period with a beacon transmitted from a gateway (GW) 100 at the foremost position is divided to an active period where each wireless node (P2P tag) transmits and receives a frame and a sleep period where transmitting and receiving of the frames are stopped. Further, the active period is divided to a plurality of timeslots each with a fixed length, and the period is partitioned to sub-periods where each type of a GW, a fixed node (P2P-S tag), and a mobile node (P2P-M tag) can transmit frames respectively. Each of the P2P tags selects a timeslot at random from the period for each type, and after waiting for a waiting period at random at the selected timeslot, it transmits a frame including information to identify the selected timeslot or the waiting period in addition to its own ID.

摘要： Disclosed is a technique to prevent a collision in a state that radio communication devices are congested. According to the technique, in the state that the radio communication devices are congested, one of the radio communication devices becomes a representative node and transmits a representative node advertisement message. When the representative node has received a data packet after transmission of the representative node advertisement message, it transmits a response confirmation message. When a radio communication device, which was not decided as the representative node, has become a normal node and received the representative node advertisement message, it transmits a data packet. Then, when receiving a confirmation message after transmission of the data packet, the radio communication device stops data packet transmission during the next active period.

摘要： In flow control apparatus formed of a network of switching hubs in a hierarchy configuration for performing data packet transfer within each of a plurality of respectively separate groups of terminals, based on use of group identifiers contained in the data packets, occurrence of congestion of the output section of a port of a switching hub is judged respectively separately for each of the terminal groups, and one or more congestion notification packets for effecting a pause in data packet transmission are generated and transmitted from that switching hub, directed only to one or more terminals of a group relating to the congestion. As a result, the effects of port congestion and of congestion control operations are limited to the terminal group concerned. Congestion can be judged for a terminal group based on a level of utilization of a port output buffer that is used only by that group, or based on a rate of flow of data from that group into a port output buffer which is used in common for all terminal groups, and congestion notification packets may be transmitted from a single port or from a plurality of ports of a switching hub, in accordance with the detected degree of congestion.

摘要： The present invention discloses a technique, according to which estimation of a position of a mobile wireless device can be accomplished in a simple system configuration by using short distance communication functions. A plurality of standard stations 110 and a plurality of connecting stations 120 are installed within a predetermined area. A mobile wireless device moving within the predetermined area has short distance wireless communication functions and receives a device ID of an opponent device (a correspondent device) each time it intersects another mobile wireless device or a standard station, and stores the device ID as an intersecting history data. When the mobile wireless device moves to a position where it can perform communication to and from a connecting station, which can make access to a position estimation device 150, the stored intersecting history data is uploaded to the position estimation device. The intersecting history data as uploaded from the mobile wireless device is stored in an intersecting history database 155. The position estimation device identifies positions of installation of all standard stations, and it estimates a moving route of the mobile communication device (for which the position is to be estimated) according to the intersecting history data directly uploaded from the mobile wireless device (for which the position is to be estimated) and a moving route of the mobile wireless device (for which the position is to be estimated) is estimated according to the intersecting history with the mobile wireless device (for which the position is to be estimated) as included in the intersecting history data of another mobile wireless device.
