Medium Access Control (MAC) protocol is the most widely used protocol for ad hoc networks. However, in practice, deafness, hidden-terminal, and exposed terminal problems are exaggerated with directional antennas, and they cause the degradation of the overall network performance. Although there are several random-access-based Medium-Access Control (MAC) protocols being proposed in the literature for networks with directional antennas, the deafness, hidden-terminal, and exposed terminal problems have yet to be fully solved. In this paper, the authors present a new MAC protocol called the DSDMAC protocol for wireless multi hop ad hoc networks using directional antennas.
