Research on Burst Services Access Mechanism for Multi-Node Cooperation

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.
