A Novel Dual Channel MAC Protocol for IEEE802.11 Ad-Hoc Networks

—In this paper, we propose a link-directionality-based dual channel MAC protocol in an attempt to double the capacities of networks using the single-channel 802.11 protocol. Simulations show that the proposed scheme can achieve more than 78% of our targeted capacities. We believe this is a first paper in the literature to propose a MAC protocol to transmit RTS/DATA and CTS/ACK of a link in different channels. This yields a large potential for multiplying the network capacities of ad-hoc networks by using only two channels.
