摘　　要：针对现有移动自组网(MANETs)TCP/IP五层体系结构通信效率低、不适合高动态交互式应用的问题,进行了无人机自组网新型通信体系结构研究。首先设计了具有代表性的应用场景,结合无人机自组网的特点,对通信体系需求进行分析,在此基础上,系统设计了通信体系结构。该结构采用具有动态认识、管理和维护功能的认知平面和具有高效数据通信功能的数据平面并行交互,其中,认知平面运用认知无线电等技术,包括发现引导、拓扑控制、移动测量和信道监控等功能模块;数据平面运用多重无线电等技术,包括高速智能的PHY层、可靠组播通信层和任务关键性的任务层等。对各层的关键技术进行了分析,并通过仿真演示说明了体系结构的可行性。该体系结构也适用于其它移动平台自组网。Aiming at the problem that the five-layer TCP/IP main communication framework of the existing mobile ad hoc networks （MANETs） has a low communication efficiency and especially misfits high dynamic and interactive applications, the authors presented a novel communication architecture for UAVs （unmanned aerial vehicles） ad hoc networks. Firstly, they imagined a representative application scenario and analyzed the communication system requirements according to the UAVs network characteristics, and then, designed the communication architecture systematically. This architecture employed the cognition plane with dynamically cognizing, managing and maintaining functions and the data plane with more efficient data traffic functions to interact in parallel. The cognition plane was grounded on cognitive radio techniques, including discovery bootstrap, topology control, mobile measurement and channel monitor modules, and the data plane was based on cognitive and multiple radios, including high-speed intellectualized PHY layer, reliable multicast communication layer and mission-centric mission layer, etc.. The analyses of the key technologies of the layering system and the simulation were conducted, and the results showed feasibility of the communication architecture. It also applies to other mobile platform self-organizing networks.
