【摘要】：目前,無人機的應用已經(jīng)從軍事領域逐漸滲透到民用的多個領域,例如災害監(jiān)測、地質(zhì)勘測、交通管制、通信中繼以及應急通訊等,并且在這些領域中已經(jīng)取得了良好的應用成效。隨著無人機應用不斷的擴展,許多任務需要多架無人機的協(xié)同,因而無人機的發(fā)展開始呈現(xiàn)出網(wǎng)絡化、編隊化的趨勢。無人機自組網(wǎng)已經(jīng)受到了各國的相關研究機構以及軍隊等部門的關注,其中的關鍵技術尤其受到這些部門的重視,而無人機網(wǎng)絡的路由技術就是受重視的關鍵技術其中之一。移動無線自組網(wǎng)的經(jīng)典路由算法直接應用于無人機自組網(wǎng)中會導致分組投遞率較低,端到端時延較高以及缺少網(wǎng)絡安全保障等許多問題,影響了無人機自組網(wǎng)的通信性能。本文主要針對無人機自組網(wǎng)的路由算法中亟待解決的兩個問題進行了研究。(1)針對無人機自組織網(wǎng)絡的高移動性和負載不均衡的特點,在路由算法中引入移動感知、負載感知算法,并對多重最短路徑算法進行改進,最終提出了一種基于移動與負載感知的多徑OLSR路由算法(MLM-OLSR,Mobility and Load aware Multipath-OLSR),并通過仿真實驗驗證提出的該路由算法的優(yōu)越性;(2)無人機自組網(wǎng)的應用場景一般具有復雜的網(wǎng)絡安全環(huán)境,容易受到惡意網(wǎng)絡節(jié)點的攻擊,這些網(wǎng)絡攻擊對任務的執(zhí)行以及其自身的生存有嚴重威脅,因此有必要對網(wǎng)絡安全問題進行研究。蟲洞攻擊是一種極其隱蔽并且危害性極大的網(wǎng)絡攻擊,本文通過對蟲洞攻擊的研究,在MLM-OLSR路由算法的基礎上,提出了一種安全感知的MLM-OLSR路由算法(Secure aware MLM-OLSR,SMLM-OLSR),該路由算法實現(xiàn)了防御蟲洞攻擊的能力。本文以QualNet仿真器為平臺,對本文的兩種路由算法分別進行建模仿真,并且通過一系列的仿真實驗驗證了新提出的兩種路由算法達到了預期的設計目標,其中MLM-OLSR路由算法相對于經(jīng)典的OLSR路由算法具有更高的分組投遞率和更低的端到端時延,SMLM-OLSR路由算法較MLM-OLSR路由算法具有更好的防御蟲洞攻擊的能力。本文提出的路由算法可以應用到無人機自組網(wǎng)中,而且對其他MANET網(wǎng)絡的路由算法研究具有一定的參考意義。
[Abstract]:At present, the application of UAV has gradually penetrated into many fields of civil use from the military field, such as disaster monitoring, geological survey, traffic control, communication relay and emergency communication, etc. With the continuous expansion of UAV applications, many missions need the cooperation of multiple UAVs, so the development of UAVs has begun to take on a network. The trend of formation. UAV ad hoc networks have attracted the attention of relevant research institutions and military departments of various countries, the key technologies of which have been paid particular attention to by these departments, The routing technology of UAV network is one of the most important technologies. The classical routing algorithm of mobile wireless ad hoc network can lead to low packet delivery rate. Many problems such as high end-to-end delay and lack of network security, This paper mainly focuses on the two problems that need to be solved in the routing algorithm of the Ad Hoc UAV network. (1) aiming at the characteristics of high mobility and load imbalance of the Ad Hoc UAV network, this paper mainly focuses on the two problems that need to be solved urgently in the routing algorithm of the Ad Hoc Unmanned aerial vehicle (UAV) Ad Hoc Network. Mobile awareness, load awareness and multiplex shortest path algorithm are introduced into the routing algorithm. Finally, a multipath OLSR routing algorithm based on mobility and load awareness is proposed. The simulation results show that the superiority of the proposed routing algorithm is the superiority of the proposed routing algorithm, and the application scenario of UAV Ad Hoc network generally has a complex network security environment. Vulnerable to malicious network nodes that pose a serious threat to the execution of tasks and to their own survival, Therefore, it is necessary to study the problem of network security. Wormhole attack is an extremely hidden and harmful network attack. Through the research of wormhole attack, on the basis of MLM-OLSR routing algorithm, In this paper, a secure aware MLM-OLSR-SMLM-OLSRA routing algorithm is proposed, which realizes the ability of defending against wormhole attacks. Based on the QualNet simulator, this paper models and simulates the two routing algorithms in this paper. And through a series of simulation experiments, it is verified that the two new routing algorithms have achieved the expected design goal. The MLM-OLSR routing algorithm has higher packet delivery rate and lower end-to-end delay than the classical OLSR routing algorithm. The SMLM-OLSR routing algorithm has better ability to defend against wormhole attack than the MLM-OLSR routing algorithm. The algorithm can be applied to UAV ad hoc network. Moreover, it has certain reference significance for the research of other MANET network routing algorithms.
