Tone Dual-Channel MAC Protocol With Directional Antennas for Mobile Ad Hoc Networks

The directional Medium Access Control (MAC) protocol improves the throughput of mobile ad hoc networks but has a deafness problem and requires location information for neighboring nodes. In the dual-channel directional MAC protocol, the use of omnidirectional packets does not require the exact location of destination node. In this paper, the authors propose a tone dual-channel MAC protocol with directional antennas to improve the throughput of mobile ad hoc networks. In the proposed MAC protocol, they use a directional CTS and an out-of-band directional DATA tone with a new blocking algorithm to improve the spatial reuse. They confirm the throughput performance of the proposed MAC protocol by computer simulations using the Qualnet simulator.
