摘　　要：太赫兹无线个域网是一种新型的无需基础设施的中心式网络,支持10 Gb/s～1 Tb/s的数据传输速率,具有广泛的应用前景。针对现有太赫兹无线个域网MAC协议和高效的太赫兹无线个域网定向MAC协议ED-MAC(Efficient Directional MAC protocol)存在节点间波束赋形训练开销大、耗时长的问题,对无线个域网内设备处于静止状态下的场景,提出一种快速高效的太赫兹无线个域网定向MAC协议FE-MAC(Fast and Efficient MAC protocol)。通过仿真验证,将提出的FE-MAC协议与基于802.15.3c的太赫兹MAC协议和ED-MAC协议进行性能对比,能够有效降低节点间数据发送时延,提高网络吞吐量。The terahertz wireless personal area network is a new type of central network without infrastructure,supporting data transmission rates of 10 Gb/s to 1 Tb/s,and has broad application prospects.The existing terahertz wireless personal area network(MAC)protocol and the efficient directional MAC protocol(ED-MAC)have the problem of large overhead and long time,so a fast and efficient terahertz wireless personal area network oriented MAC protocol FE-MAC(Fast and Efficient MAC protocol)is proposed in this paper.Through simulation verification,the proposed FE-MAC protocol is compared with the 802.15.3c-based terahertz MAC protocol and ED-MAC protocol,which can effectively reduce the data transmission delay between nodes and improve network throughput.
