摘　　要：针对现有太赫兹无线个域网MAC协议存在信道利用率低的问题,提出一种快速传输的太赫兹无线个域网MAC(Fast Transmission MAC Protocol for THz Wireless Personal Area Network,FTP-MAC)协议,FTP-MAC协议采用多对节点并行传输机制,在信道互不干扰的情况下实现了多对节点在同一时刻内同时传输的功能,通过OPNET仿真工具进行仿真验证。相较于LODMAC协议和TAB-MAC协议,FTP-MAC协议在吞吐量、信道利用率和网络整体的数据传输效率等性能方面都有所提高。In order to solve the problem of low channel utilization of existing terahertz wireless personal area network MAC protocol,a fast transport protocol for terahertz wireless personal area network (FTP-MAC) is proposed.The FTP-MAC protocol uses parallel transmission mechanism of multiple pairs of node to realize the simultaneous transmission of multiple pairs of node without channel interference.The simulation is carried out with OPNET,and the results show that FTP-MAC protocol can effectively improve channel utilization,reduce data transmission delay and improve the overall data transmission efficiency and throughput of the network,compared with LODMAC protocol and TAB-MAC protocol.
