摘要 Ad Hoc MAC协议可以使用定向天线来提高信道复用率,从而提高网络的容量。但是,使用DMAC协议会导致"听不见"问题,并且网络的吞吐量较低。虽然对此已有一些改进,减轻了"听不见"问题,但依旧存在网络吞吐量的问题。文中主要针对DMAC的缺陷和不足,提出了一种基于定向天线的双信道MAC协议,将控制信息以全向天线在控制信道上发送,数据信息以定向天线在数据信道上发送,进一步减轻"听不见"问题并且提高了信道复用率。模拟仿真测试表明,这种基于双信道定向天线的MAC协议对DMAC中的缺陷和不足有较大的改进。 Ad Hoc MAC protocols using directional antennas can be used to improve the channel reuse rate,thus rising networks capacity. But,using MAC protocol has the problem of deafness and a poor throughput performance. There is some improvement to these problems and the problem of deafness is mitigated,but throughput performance is still poor. In this paper,considering flaw and shortage of DMAC protocol,propose a dual-channel MAC protocol using the omnidirectional antenna for control channel and directional antennas for data channel. A dual-channel MAC protocol using directional antennas is proposed to mitigate deafness problem and improve the channel re-use rate. Simulation tests show the MAC protocol based on dual-channel directional antennas has better improvement for flaw and short-age of DMAC.
