摘要

针对定向天线引起的终端隐藏问题和旁瓣干扰问题,提出了一种面向移动自组网(MANET)的带忙音多址协议BT- dmacp。BT-DMACP集成了RTS/CTS (request- send/clear- send)握手、定向忙音和功率控制算法,精确控制传输功率,最大限度地减少旁瓣干扰。设计了一种自适应算法来估计接收机处的干扰功率。仿真结果表明,BT-DMACP协议有效地支持定向天线的应用,具有较高的信道利用率和较低的能耗。

A novel power control multiple access protocol for ad hoc networks with directional antennas
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.
