K.SaiPriyanka, P.Vasanthi, D.Venkatesh

In Ad Hoc networks achieving high throughput is possible when directional antennas are applied. The directional antennas result in higher spatial multiplexing gain. However, there are some problems in practice that include exposed terminal problems, deafness and hidden terminal causing the deterioration of the performance of the network. There are many MAC protocols that have been proposed, the solution proposed by Abdullah et al. is capable of solving the problems of exposed terminal, deafness and hidden terminal where a new MAC protocol is implemented using dual sensing strategy. The Spintool is used for validation of the protocol integration. In this paper, we have practically implemented the MAC protocol with directional antennas. The simulation results reveal that the proposed MAC protocol is capable of solving the problems of deafness, hidden terminal and exposed terminal problems. The results are compared with many existing protocols.
