Abstract :
A multiple access protocol with busy tone (BT) for mobile ad hoc network (MANET) using directional antennas, named as BT-DMACP, is proposed with consideration of the hidden terminal problems and side lobe interference caused by directional antennas. The RTS/CTS (request-to-send/clear-to-send) handshake, directional busy tones and power control algorithm are integrated in BT-DMACP to accurately control the transmission power and minimize the side lobe interference. An adaptive algorithm is designed to estimate the interference power at the receiver. Simulation results show that BT-DMACP protocol effectively supports the application of directional antennas and provides higher channel utilization and lower energy consumption.
