【摘要】：針對傳統(tǒng)TDMA網(wǎng)絡(luò)節(jié)點間業(yè)務(wù)量不均勻時,會造成信道資源嚴重浪費的問題,設(shè)計了一種基于鄰居時隙調(diào)動的短波地空網(wǎng)動態(tài)TDMA協(xié)議(NTR-TDMA),以可靠性較高的地面節(jié)點作為控制中心,實現(xiàn)時隙分配可控下的動態(tài)利用。提出了鄰居時隙調(diào)動算法(NTR-ALG),地面節(jié)點根據(jù)時隙估計過程后生成的節(jié)點時隙請求數(shù),調(diào)動相鄰業(yè)務(wù)時隙節(jié)點間的空閑時隙,重新劃分節(jié)點業(yè)務(wù)時隙界限。利用OPNET平臺進行性能仿真,并與HFTP協(xié)議和TDMA協(xié)議作了對比分析。仿真結(jié)果表明,NTR-TDMA相比HFTP協(xié)議和TDMA協(xié)議,在消息投遞率、平均時延和吞吐量方面具有更優(yōu)異的性能。
[Abstract]:When the traffic between nodes in traditional TDMA network is not uniform, it will cause serious waste of channel resources. In this paper, a dynamic TDMA protocol based on neighbor time slot is designed for dynamic TDMA protocol of HF ground to air network. The ground node with high reliability is used as the control center. In order to realize the dynamic utilization of time slot allocation under controllable control, a neighbor slot transfer algorithm is proposed, and the number of slot requests generated by the ground node according to the time slot estimation process is proposed. The idle time slots between adjacent service slot nodes are mobilized, and the service slot boundaries of the nodes are re-divided. The performance simulation is carried out using the OPNET platform. Compared with HFTP protocol and TDMA protocol, the simulation results show that NTR-TDMA is compared with HFTP protocol and TDMA protocol in message delivery rate. Better performance in terms of average delay and throughput.

【正文快照】： 為了節(jié)點有效利用信道資源,一般通過媒質(zhì)接入控制(media access control,MAC)協(xié)議來協(xié)調(diào)節(jié)點接入無線信道的時間[1]。短波數(shù)據(jù)鏈的組網(wǎng)接入技術(shù)主要以輪詢、令牌環(huán)以及TDMA為主[2]。輪詢[3]方式時延大,不能有效地滿足戰(zhàn)術(shù)消息的實時性傳輸需求。令牌環(huán)[4]方式存在著令牌傳遞開，
