【摘要】：战术互联网已经广泛应用于现代战争之中,其性能的好坏影响甚至决定着战争的胜负。对战术互联网络中各个关键技术进行深入研究对于提升我国军事力量有着重大的意义。现阶段,我军正在积极建设新一代战术互联网络,为建设出适合于我国现代化军事战场的战术信息网络,需要对新的网络技术进行深入研究,同时根据我军的作战情况,提出切实可行的方案。本课题基于美军的WNW波形,对战场移动自组织网络中的路由技术进行了深入研究。重点研究了 OLSR路由协议,并基于WNW波形协议栈和应用场景对其进行了改进,使其能够更有效的应用于战术互联网中。本文的主要工作包括:(1)结合移动自组织网络路由协议和OLSR路由协议的研究现状对移动自组织网络中的路由技术进行了详细的介绍,主要分析了移动自组织网络路由协议的特点、分类、设计条件和设计要求。(2)分析了 OLSR路由协议的原理和无线网络跨层设计的常用方法,结合WNW波形和OLSR协议的特点,采用三种手段对OLSR协议进行了优化。首先,通过精简分组和消息格式降低了路由开销;然后,基于节点稳定性改进了 MPR选择算法,新的算法考虑到了网络的密度和节点的移动性,能够提升路由的稳定性;最后,基于WNW波形协议栈,设计了一种跨层设计方案,该方案有效地降低了路由开销,提升了网络的整体性能。(3)利用仿真手段,使用OPNET仿真软件对提出的OLSR改进协议进行了叠加实现,分别在不同场景中与标准OLSR路由协议进行了对比并分析实验结果。结果表明本文提出的改进协议的性能与标准OLSR协议相比有了较大提升,特别是在移动环境中,其性能明显优于标准OLSR。本课题中对WNW波形网络中的路由协议的研究有助于我国战术互联网的发展,对我军新一代战术通信网络的发展具有重要的参考价值。
[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.
