    Abstract: The most popular MAC protocol for mobile ad Hoc networks is IEEE 802.11 MAC specification which allows practical use of eight channels in 802.11a and three in 802.11b. In order to improve network throughput several multi-channel MAC protocols which allow multiple channels operation have been proposed for IEEE 802.11 Ad Hoc networks. However, simultaneous multiple channels operation is still not allowed because there is only one wireless transceiver per node in above schemes. This study  introduces a novel multi-channel based scheme for multi-hop 802.11 Ad Hoc networks of which each node has multiple transceivers, which can resolve exposed terminals problem, hidden terminals problem and intruding terminals problem effectively. The MAC protocol in the scheme is also provided. Numerical results show that network throughput is significantly improved with more transceivers per node.
