Exploiting Rate Diversity for Multicasting in Multi-Radio Wireless Mesh Networks
: A multi-rate capable IEEE 802.11a/b/g node can utilize different link-layer transmission rates. Interestingly, multi-rate capability is defined by IEEE 802.11 standards only for unicast transmissions. In this paper, we consider a novel type of multi-radio multi-channel wireless mesh network (WMN) where a radio can mulicast at different link-layer transmission rates to its neighbors. Such link-layer multi-rate multicast capability will enable lowlatency network-layer broadcast/multicast for multimedia. In our previous work, we assumed a “fully multi-rate multicast” (FMM) framework in which nodes can adjust link-layer multicast transmission rate for each link-layer frame. We propose a new framework called “single bestrate multicast” (SBM) that exploits the link-layer rate diversity by enabling each WMN to decide, depending on its topological properties, a single transmission rate for all its link-layer data multicasts. Although, FMM improves performance significantly, employi...
