| Sumario: | 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. |
