摘要
针对战术协同组网数据链延时大、容量小的问题,为满足基于突发业务战术网络低延时、大容量的要求,以战术瞄准网络技术(TTNT)为背景,提出一种基于多路同时接收的阈值自适应接入体制(MR-ATMA,Adaptive Threshold Multiple Access Based on Multi-Channel Simultaneous Reception)。该接入体制采用分层设计的开放式体系架构,物理层采用基于快速跳频的多路同时接收技术,实现了虚拟全双工传输模式;MAC层采用基于信道负载感知的阈值自适应接入技术,能够实现突发业务的快速接入。与基于单收处理的接入体制(SR-ATMA,Adaptive Threshold Multiple Access Based on Single-Channel Reception),CSMA,TDMA等接入体制相比,MR-ATMA具有更高的信道利用率和更低的接入延时,能很好地适用于具有突发业务特点的战术网络。
To solve the problem of large delay and small capacity of tactical cooperative network data link,in order to meet the requirements of low delay and large capacity in tactical network,a threshold adaptive access mechanism based on multi-channel simultaneous reception is proposed based on tactical targeting network technologies(TTNT).A layered open architecture is adopted in this mechanism,and the physical layer adopts multi-channel simultaneous receiving technology based on fast frequency hopping to realize virtual full-duplex transmission mode.The MAC layer adopts threshold adaptive access technology based on channel load statistics,which can realize fast access of burst service.Compared with SR-ATMA,CSMA,TDMA and other access mechanisms,it has higher channel utilization and lower access delay,and can be well applied to the tactical network with the characteristics of burst service.
