Abstract:
1. A wireless communication device for operating under a communication environment constructed by communication stations transmitting beacons describing network-related information to each other at predetermined time intervals, said device comprising: a communication unit configured to transmit and receive wireless data; a beacon signal generating unit configured to generate beacon signals describing information relating to an own station; a beacon signal analyzing unit configured to analyze beacon signals received from nearby stations by said communication unit; a timing control unit configured to control beacon transmission timing with said communication unit; and a collision avoiding unit configured to avoid beacon collisions occurring with other stations, wherein said collision avoiding unit performs a scanning operation to detect beacons from other stations in response to reception of a beacon from a nearby station describing information indicating warning of an abnormal status, or in response to not being able to detect a beacon from said other station over said predetermined time interval, and acquires information described in beacons transmitted from nearby stations.
