Abstract A Busy Tone and Directional antenna Multiple Access Control Protocol with power control (BT-DMACP) for Mobile Ad hoc NETwork (MANET) is proposed. The special hidden terminal problems and side lobe interference in directional antennas used network are considered. Through RTS/CTS handshake mechanism, directional busy tone signals and the power control method, the directional transmission power of data packets can be adjusted in time. In order to estimation of the maximal interference power supported by receiving node, an adaptive estimation algorithm is presented. Simulation results show that BT-DMACP supports effectively the application of directional antennas and provides higher channel utilization and lower energy consumption.
