Multicast in 802.11 WLANs: An Experimental Study

Tags:
multicasting

Overview While the deployment of WiFi networks continues to grow at an explosive rate, the multicast multimedia delivery service on WiFi compliant devices is still in its early stage of development. The real culprit is the IEEE 802.11 MAC protocol, and in particular, the absence of feedback mechanism when multicast is used. Recently, a leader-based mechanism has been proposed to overcome this problem. This paper measures the characteristics of the legacy multicast transmission mechanism and analyze its flaws. Then, it studies the performance of the leader-based approach and compares its performance with the standard multicast service.
