摘要：
With recent advances in wireless technology, the ability to use multiple transmission rates and multiple network interface cards (radios) in wireless networks has been widely recognized. In this paper, Multi-Rate and Multi-Radio (MR2) characteristics are exploited to reduce end-to-end transmission delay for reliable multicasts. To achieve this goal, a new routing metric, MR2_ETT, is introduced. It accounts for the link transmission time by considering the usable number of radios and the transmission rate on the link. This metric is used in a routing protocol that is also proposed in this work. The routing protocol, termed Multi-rate Multi-radio On-Demand Multicast Routing Protocol (MR2_ODMRP), makes ODMRP suitable for a MR2 environment. Simulation results show that MR2_ODMRP outperforms ODMRP in multi-rate or multi-radio wireless mesh networks.
