Abstract

In recent years, the evolution of modern applications in wireless networks has led to the use of 60 GHz frequency band due to its 7 GHz license - free spectrum allocated worldwide. Using this physical layer demands an adaptation of the Medium Access Control (MAC) layer to enhance its performance. In this paper, we propose a scheme based on the adaptation of the IEEE 802.11ad standard MAC protocol for WLANs using the “busy tone” approach and directional antennas with coordination between 60 GHz and 2.4 GHz frequency bands. Simulation results show the efficiency of this model in reducing collisions caused by hidden terminals, therefore, enhancing the performance of the network in terms of transmission delay, retransmission attempts and throughput.
