The main purpose of beaconing in the legacy IEEE 802.11 networks is maintaining stations clock synchronization. Recently appeared 11s Amendment specifying mesh networking makes beacons responsible for supporting the mesh deterministic access method (MDA) designed for delay-sensitive multimedia applications. In this paper, we study the legacy beaconing scheme and show its inability to support the MDA in a typical mesh network use case. We propose a P-persistent beaconing approach to improve the MDA support and analyze its efficiency. The simulation results show that applying the P-persistent approach successfully maintains and protects the channel reservations obtained via MDA.
