基于双信道定向天线的Ad Hoc MAC协议的研究
Research on Ad Hoc MAC Protocol Based on Dual-channel Directional Antennas
摘要
Abstract
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.关键词
