To resolve the problem that the standard aggregation frame mechanism and slot application method of the existing IEEE802.15.3c and High Efficient Fairness MAC(HEF-MAC) protocol applied to the terahertz wireless personal area network is not perfect, a high time slot utilization MAC protocol for terahertz wireless personal area networks(HTSU-MAC) is proposed. By using the new mechanism such as on-demand retransmission of frame aggregation and utilization of no-acknowledged time slot, HTSU-MAC makes the channel slot resources used efficiently and the network throughput greatly improved. The theoretical analysis proves the superiority of the protocol, and the simulation results show that the HTSU-MAC protocol has better network performance than other protocols.
