The Directional MAC Protocol Design in mm-Wave Ad Hoc Network

Abstract

The stations that connect directly to each other increases the spatial reuse in wireless ad hoc network However the interference s and collision s between stations is an important issue Hence this thesis will focus on MAC /PHY layer design and the application of transmit power control In this thesis the MAC layer is based on 802 11 DCF protocol First t he several system performance indicators between different kinds RTS/CTS are t heoretically analyzed and simulated And the simulation results show directional RTS/CTS is much better However the directional RTS/CTS only inform the stations in specific direction Other stations will sense the channel as idle and transmit It may cause severe collision s Therefore this thesis proposes th at adjusting the transmit power through the channel gain information so as to decrease the interference s and collisions Simulation results show that our proposed scheme can imp rove the system throughput and enhance the energy efficiency
