The directional antennas increase the spatial reuse, improve the transmission reliability, extend the transmission range and/or save the power consumption in the network. However, with directional antenna's advantages, some serious issues like deaf and hidden node problem come. Due to these issues, the people fail to get full exploitation of directional antennas. Several directional MAC protocol were suggested in last decays, to take full benefits of the antenna. In this paper, the authors simulate some directional MAC protocol with the help of OPNET 14.5. They compare the simulation results of those directional MAC protocols in the terms of throughput and delay metric.
