Multimedia services are a major application for IEEE 802.11 WLANs but the current standard does not utilize any rate adaptation technique for multicasting. SARM (SNRbased auto rate for multicast) is a new rate adaptation mechanism for multicasting multimedia content in IEEE 802.11 WLAN environments. Since there is no RTS/CTS or MAC ACK frame in multicast packet transmissions, SARM uses an auxiliary signaling method to obtain the channel quality for each mobile node. By adapting a transmission… CONTINUE READING
