| 摘 要： | 针对现有无线网络媒体访问控制(MAC)协议难以在太赫兹（THz）载频条件下实现10Gbps级别超高速无线接入的问题，提出一种新的太赫兹超高速无线网络MAC协议——MAC-T。MAC-T设计了新的时分多路访问(TDMA)+载波侦听多路访问(CSMA)自适应混合MAC接入机制和一种新的超帧结构，并定义了对应于太赫兹通信的关键参数，从而使最大数据传输速率达到10Gbps以上。理论分析和仿真结果表明：MAC-T协议能够在太赫兹无线网络中正常运行，数据传输速率达到了18.3Gbps，是IEEE 802.15.3c标准定义的最大速率5.78Gbps的2.16倍，数据帧的平均接入时延约为0.0044s，性能相对于IEEE 802.15.3c标准提高了42.1%，从而在MAC协议方面为太赫兹超高速无线网络的研究和应用提供了有力支撑。

| Abstract: | To realize 10Gbps level wireless access under the condition of terahertz (THz) carrier frequency, a new Medium Access Control (MAC) protocol for THz ultra-high data-rate wireless networks, MAC-T (Medium Access Control for THz) was proposed in this paper. In MAC-T, a new TDMA (Time Division Multiple Access)+CSMA (Carrier Sense Multiple Access) adaptive hybrid MAC access control mechanism and a new superframe structure were designed. Moreover, some key parameters corresponding to terahertz communications were defined. Therefore, MAC-T could make the maximum data transmission rate reach up to 10Gbps or higher. The theoretical analysis and simulation results show that MAC-T can operate normally in terahertz networks and the data rate can reach up to 18.3Gbps which is 2.16 times 5.78Gbps that IEEE 802.15.3c can achieve. Meanwhile, the average access delay of MAC-T is 0.0044s which improves about 42.1% compared with that of IEEE 802.15.3 which is 0.0076s. Thus, MAC-T can provide significant support in the research and application of terahertz ultra-high data-rate wireless networks. |
