【摘要】：戰(zhàn)術互聯(lián)網已經廣泛應用于現(xiàn)代戰(zhàn)爭之中,其性能的好壞影響甚至決定著戰(zhàn)爭的勝負。對戰(zhàn)術互聯(lián)網絡中各個關鍵技術進行深入研究對于提升我國軍事力量有著重大的意義�，F(xiàn)階段,我軍正在積極建設新一代戰(zhàn)術互聯(lián)網絡,為建設出適合于我國現(xiàn)代化軍事戰(zhàn)場的戰(zhàn)術信息網絡,需要對新的網絡技術進行深入研究,同時根據(jù)我軍的作戰(zhàn)情況,提出切實可行的方案。本課題基于美軍的WNW波形,對戰(zhàn)場移動自組織網絡中的路由技術進行了深入研究。重點研究了 OLSR路由協(xié)議,并基于WNW波形協(xié)議棧和應用場景對其進行了改進,使其能夠更有效的應用于戰(zhàn)術互聯(lián)網中。本文的主要工作包括:(1)結合移動自組織網絡路由協(xié)議和OLSR路由協(xié)議的研究現(xiàn)狀對移動自組織網絡中的路由技術進行了詳細的介紹,主要分析了移動自組織網絡路由協(xié)議的特點、分類、設計條件和設計要求。(2)分析了 OLSR路由協(xié)議的原理和無線網絡跨層設計的常用方法,結合WNW波形和OLSR協(xié)議的特點,采用三種手段對OLSR協(xié)議進行了優(yōu)化。首先,通過精簡分組和消息格式降低了路由開銷;然后,基于節(jié)點穩(wěn)定性改進了 MPR選擇算法,新的算法考慮到了網絡的密度和節(jié)點的移動性,能夠提升路由的穩(wěn)定性;最后,基于WNW波形協(xié)議棧,設計了一種跨層設計方案,該方案有效地降低了路由開銷,提升了網絡的整體性能。(3)利用仿真手段,使用OPNET仿真軟件對提出的OLSR改進協(xié)議進行了疊加實現(xiàn),分別在不同場景中與標準OLSR路由協(xié)議進行了對比并分析實驗結果。結果表明本文提出的改進協(xié)議的性能與標準OLSR協(xié)議相比有了較大提升,特別是在移動環(huán)境中,其性能明顯優(yōu)于標準OLSR。本課題中對WNW波形網絡中的路由協(xié)議的研究有助于我國戰(zhàn)術互聯(lián)網的發(fā)展,對我軍新一代戰(zhàn)術通信網絡的發(fā)展具有重要的參考價值。
[Abstract]:Tactical Internet has been widely used in modern warfare, The quality of its performance even determines the victory or defeat of the war. It is of great significance to study the key technologies in the Tactical Internet to enhance the military strength of our country at this stage. Our army is actively building a new generation of tactical Internet networks. In order to build a tactical information network suitable for our country's modern military battlefield, we need to conduct in-depth research on new network technologies, and at the same time, according to our army's operational situation, Based on the WNW waveform of the US military, the routing technology in the battlefield mobile ad hoc network is deeply studied in this paper, and the OLSR routing protocol is emphatically studied. Based on the WNW waveform protocol stack and application scenario, it is improved. The main work of this paper is to introduce the routing technology in mobile ad hoc network (Manet) combined with the research status of mobile ad hoc network routing protocol and OLSR routing protocol. This paper mainly analyzes the characteristics, classification, design conditions and design requirements of mobile ad hoc network routing protocols. It analyzes the principle of OLSR routing protocols and the common methods of cross-layer design of wireless networks, combining with the characteristics of WNW waveform and OLSR protocol. The OLSR protocol is optimized by three methods. Firstly, the routing overhead is reduced by reducing the packet and message format; then, the MPR selection algorithm is improved based on node stability. Considering the density of the network and the mobility of nodes, the new algorithm can improve the stability of the routing. Finally, based on the WNW waveform protocol stack, a cross-layer design scheme is designed, which effectively reduces the routing overhead. The whole performance of the network is improved. (3) the improved OLSR protocol is implemented by using the OPNET simulation software by means of simulation. Compared with the standard OLSR routing protocol in different scenarios, the experimental results show that the performance of the proposed improved protocol is much better than that of the standard OLSR protocol, especially in mobile environment. The research of routing protocol in WNW waveform network is helpful to the development of Tactical Internet in our country and has important reference value to the development of the new generation of Tactical Communication Network of our army.
