Wireless communication system and wireless communication control method, wireless communication device and wireless communication method, and computer program

摘要

A wireless communication device in a wireless network sets management information notification cycles at specified time intervals and transmits management information containing receive timing information showing its own position to start receiving information, receive window information, and receive cycle information. Another wireless communication device receiving that management information links it to a communication device number for the corresponding wireless communication device and stores the receive timing, the receive window information, and the receive cycle information. When sending information, the receive start position of the corresponding communication device is found from the receive timing information, the receive window information, and the receive cycle information of the other communication and information is then transmitted at that timing. An asynchronous ad-hoc communication wireless network can therefore be configured without a particular control station.

主权项

1. A wireless communication device among a plurality of devices in a network where the plurality of devices directly communicate with each other without utilizing an access point, the wireless communication device comprising:
circuitry configured to
receive notified management information elements for a low power consumption operation, from at least one another wireless communication device, among the plurality of devices, serving as a receiving destination wireless communication device;detect an absence time information of the another wireless communication device serving as the receiving destination wireless communication device, based on the notified management information elements, the absence time information notifying for communicating asynchronously without continuously being in receive standby, wherein signals are receivable during receive standby;manage a plurality of timings of receive operations of the wireless communication device based on the absence time information which describes the plurality of timings of receive operations before a next management information element is sent;receive a transmission information that is generated by a device other than the receiving destination wireless communication device;decide that the transmission information is addressed to the receiving destination wireless communication device; andtransmit, in a receive operation of the another wireless communication device that is next in time, the transmission information to the another wireless communication device serving as the receiving destination wireless communication device according to the at least one of the managed plurality of timings of receive operations, wherein the notified management information elements include duration information for showing receive or absence times, interval information for designating position where the duration is periodically installed, start time information for notifying start time setting in the interval, and notification count information for showing cycle of notifications of the management information.
