摘　　要：太赫兹通信作为未来超高速无线通信的关键技术,能满足10Gbps以上的传输速率,太赫兹无线个域网定向MAC协议为太赫兹无线个域网的关键技术之一,该文章针对现有的相关MAC协议以及802.15.3c标准存在的缺点提出了一种公平低时延的太赫兹无线个域网定向MAC协议——FLL-MAC协议.文章内提出了3种新机制,分别是新的时隙分配机制、聚合帧子标头重传机制和入网时隙请求结合机制,解决了时隙分配不公平问题、减小了波束赋形开销、降低了入网碰撞概率.As the key to future high-speed wireless communication technology,Terahertz communication can meet the transfer rate of up to 10 GBPS,directional MAC Protocols for Terahertz Wireless Personal Area Network(TWPAN)is one of the key technology of Terahertz Wireless Personal Area Network,In this paper,A fairly and low Latency of MAC protocol for Terahertz Wireless Personal Area Network(FLL-MAC)protocol is proposed for the existing Terahertz MAC protocols and 802.15.3 c standard.The proposed new time slot allocation mechanism,the retransmission mechanism of the aggregated frame subheader and the combination mechanism of the access and time slot request solved the problem of unfair slot allocation,reduced the beam forming cost and reduced the access collision probability.
