Abstract
A method for deterministic directional discovery of neighbor devices by a device in a wireless network comprises dividing equally an access time to a discovery channel to predefined number of sector scanning periods (), wherein each sector scanning period includes a predefined number of discovery sweep periods (), and each discovery sweep period includes a predefined number of time slots (); scanning the discovery channel in a single sector during a current sector scanning period (S); transmitting a discovery frame towards each sector during each time slot of each discovery sweep period of the current sector scanning period (S); checking if at least one response to a transmitted discovery frame has been received during the current sector scanning period (S); and setting the device to scan the discovery channel in a next sector during a next sector scanning period, thereby sequentially accessing the predefined number of sector scanning periods (S).
