【摘要】：數(shù)據(jù)鏈由消息格式、鏈路協(xié)議和傳輸通道構(gòu)成,主要功能是完成武器系統(tǒng)、指控系統(tǒng)與傳感器之間的實(shí)時(shí)信息交換,并且處理火力控制、指控控制和戰(zhàn)場(chǎng)態(tài)勢(shì)等戰(zhàn)術(shù)信息。作為主戰(zhàn)武器、指揮控制系統(tǒng)與傳感器無(wú)縫連接的重要紐帶,數(shù)據(jù)鏈?zhǔn)菍?shí)現(xiàn)信息系統(tǒng)與武器系統(tǒng)一體化的重要手段和有效途徑,它已成為提高武器系統(tǒng)信息化水平和整體作戰(zhàn)能力的關(guān)鍵。 網(wǎng)絡(luò)資源動(dòng)態(tài)管理是數(shù)據(jù)鏈的核心內(nèi)容,優(yōu)秀的網(wǎng)絡(luò)管理方法和高效的接入算法能夠有效的降低端到端延時(shí),顯著的增加網(wǎng)絡(luò)吞吐量,大大的提高數(shù)據(jù)包的投遞率,對(duì)整個(gè)網(wǎng)絡(luò)的性能有很大的提升。本文主要研究了Link22的動(dòng)態(tài)接入技術(shù),提出ATH-TDMA和SWAP-TDMA兩種動(dòng)態(tài)時(shí)隙分配算法,其中前者的時(shí)隙轉(zhuǎn)讓過(guò)程發(fā)生在業(yè)務(wù)時(shí)隙相鄰的節(jié)點(diǎn)之間,后者的時(shí)隙轉(zhuǎn)讓發(fā)生在整個(gè)網(wǎng)絡(luò)循環(huán)結(jié)構(gòu)中。 同時(shí),本文根據(jù)排隊(duì)論理論模型提出了時(shí)隙評(píng)估算法,使用靜態(tài)和動(dòng)態(tài)兩種評(píng)估手段,預(yù)測(cè)下一時(shí)幀某個(gè)節(jié)點(diǎn)的時(shí)隙狀態(tài)。 最后,使用網(wǎng)絡(luò)仿真工具OPNET對(duì)Link22系統(tǒng)和兩個(gè)動(dòng)態(tài)時(shí)隙分配算法進(jìn)行建模仿真,通過(guò)仿真,得到兩個(gè)算法的時(shí)延、吞吐量、時(shí)隙利用率和丟包率等性能,并與靜態(tài)時(shí)隙分配算法進(jìn)行比較,證明了算法的合理性和可靠性。
[Abstract]:The data link is composed of message format, link protocol and transmission channel. The main function of the data link is to complete the real-time information exchange between the weapon system, the command system and the sensor, and to handle fire control. As an important link between command and control system and sensor, data link is an important means and effective way to realize the integration of information system and weapon system. It has become the key to improve the information level of weapon system and the overall combat capability. Dynamic management of network resources is the core of data link. Excellent network management methods and efficient access algorithms can effectively reduce end-to-end delay, significantly increase network throughput, and greatly improve the delivery rate of data packets. In this paper, the dynamic access technology of Link22 is studied, and two dynamic slot allocation algorithms, ATH-TDMA and SWAP-TDMA, are proposed. The time slot transfer process of the former occurs between adjacent nodes. The time slot transfer of the latter occurs throughout the network cycle structure. At the same time, based on the queuing theory model, a slot evaluation algorithm is proposed, which uses static and dynamic evaluation methods to predict the slot state of a node in the next frame. Finally, the network simulation tool OPNET is used to model and simulate the Link22 system and two dynamic slot allocation algorithms. Through simulation, the delay, throughput, slot utilization and packet loss rate of the two algorithms are obtained. Compared with the static slot allocation algorithm, the rationality and reliability of the algorithm are proved.
