57) Abstract :
This invention explains a system and a method for sending beacons in wireless personal area networks
having a medium access control mechanism the said system comprising: a superframe structure, having all
beacons from different devices grouped at the start of the divided in several data slots; a beacon frame
structure, including an element called Beacon Slot Reservation Indicator (BSRI) which contains the
information about all the occupied beacon slots from the reference of the device which is sending the beacon;
a beacon elements, New Beacon Information Element (New Beacon IE) where if devices hear a beacon from
a neighboring device for the first time, then it sends New Beacon IE in its beacon as an indication of the New
Device joining; and new DEVID structure, for addressing using information of device's MAC address and
beacon slot number where device is sending its beacon and also by using information of device's MAC
address and number obtained from MAS number where device is sending its beacon; a method for resending
beacon using RSS procedure on detection of beacon collision.
