高时隙利用率太赫兹无线个域网MAC协议

摘要

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,HTSUMAC 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.%针对现有的IEEE802.15.3c及高效公平(High Efficient Fairness MAC protocol,HEF-MAC)等相关接入协议涉及的标准聚合帧机制及时隙申请方式应用到太赫兹无线个域网尚不完善的问题,提出了一种高时隙利用率太赫兹无线个域网MAC协议(HTSU-MAC).HTSU-MAC通过采用帧聚合内容按需重传以及无确认时隙利用等新机制,使得信道时隙资源得以高效利用,网络吞吐量得以极大提升.理论分析验证了该协议的优越性,仿真结果表明,HT-SU-MAC协议较其他协议具有更好的网络性能.
