Research on Video MAC for QoS-Guaranteed

Video Transport over IEEE 802.11 WLAN


Administrative Data




Project Summary




        We understand problems and demands of MAC layer multicast transmission in IEEE 802.11 WLAN, and develop efficient WLAN MAC layer multicast rate adaptation. Also, we evaluate WLAN MAC layer multicast transmission based on various multimedia application scenario. Finally, through NS-2 simulation, we analyze our proposals performance.

        Based on our multicast algorithm that adapts transmission rate in WLAN MAC and NS-2 simulation result, we can participate in working group for IEEE 802.11v standard. Building testbed for multicast transmission rate technique depending on Future WLAN environment is expected.
