Abstract:
1. A wireless communication system of a self-organized distribution type, comprising: a plurality of communication stations each configured to function as a local station and to transmit a beacon, including information pertaining to a network, at different times in a predetermined frame period, wherein each of the plurality of communication stations is configured to provide a predetermined reception period before and after a beacon transmission time of the beacon transmitted from a neighboring station of the plurality of communication stations, the neighboring station transmitting the beacon before the local station, and is configured to perform information transmission before and after a beacon transmission time of the beacon transmitted by a designated one of the plurality of communication stations, which is identified to receive the information transmission, when a certain communication station transmits information toward all of the other communication stations, each of the plurality of communication stations performs an information transmission method, in which information is sequentially transmitted to a respective next communication station transmitting the beacon next to the local station in said predetermined frame period by using reception periods provided before and after the beacon transmission time of the respective next communication station, or before and after the beacon transmission time of the local station, and after data giving notice of performing the information transmission is sequentially transmitted from a communication station functioning as an information transmission source to all of the other communication stations in one frame, said information transmission source transmits the information continuously to the beacon transmission of the local station in a next frame period, and the other communication stations receive the beacon and the transmission information in a receiving timing of the beacon from the information transmission source.
