Abstract
A method and system for directed beaconing in a superframe structure () among devices of different types in a Wireless Personal Area Network (WPAN). A first type device directs a second type device to transmit beacons () in a beacon group of first type devices, announcing the second type device's time slot reservations (). The method includes: making a Distributed Reservation Protocol (DRP) reservation () of a time period in every superframe; selecting two consecutive beacon slots () and indicating the two consecutive beacon slots () as occupied; informing the second type device the timing of the two occupied consecutive beacon slots during the reserved time period (); transmitting a response () in the reserved time period by the second type device; and transmitting two beacons () by the second type device in the two occupied consecutive beacon slots.
