Abstract:
1. A radio communication apparatus in a wireless network system in which a plurality of radio communication apparatuses transmit beacons to each other, the radio communication apparatus comprising: an address processor that: (i) generates a first unicast address from a first address range, the first unicast address being a temporary address, (ii) generates a second unicast address randomly to attempt to be unique, from a second address range, and (iii) associates the first unicast address and the second unicast address with a single MAC (Media Access Control) processing unit; a beacon processor that determines whether or not a conflict exists between the second unicast address generated by the address processor and a second unicast address of another radio communication apparatus; and a transmitter that, in response to the beacon processor determining that the conflict exists, switches a value of a source address field of a data frame to be set from the second unicast address generated by the address processor to the first unicast address generated by the address processor and transmits the data frame to another radio communication apparatus in a data period, whereby the data frame includes as the source address the first unicast address generated by the address processor.
