Multimedia multicast performance analysis for 802.11n network cards

The technical evolution of Wi-Fi networks has made it possible to attain very high speeds for delivering content to users. However multicast transmissions never received the same level of attention as unicast transmissions in the IEEE802.11n standard. In this paper, we experimentally assess the viability of employing commercially available IEEE802.11n hardware to multicast real-time multimedia content, requiring high bandwidth and low delay. We verify the performance of the leader based multicast scheme and compare it to the standard multicast scheme.
