摘要:

针对未来航空集群作战的全新网络需求,提出了“航空集群云网络”的概念,设计了网络通信层面与任务需求层面耦合机制,为航空集群网络的具体通信技术研究提供了参考,并在此基础上结合基于正交频分多址(orthogonal frequency division multiple access, OFDMA)的可变带宽信道分配技术设计了一种面向航空集群云网络的媒体接入控制协议(aeronautic swarm cloud network oriented media access control protocol, ASCN-MAC)。详细设计了协议的任务需求认知机制,为智能化任务规划决策提供了通信支撑,并从需求出发,基于OFDMA的特点,提出了面向任务需求的层次化信道资源预约方式和信道资源贪婪预约算法。仿真结果表明,ASCN-MAC协议在任务规划决策的通信支撑能力、吞吐量性能和实时性上均具备较强的优势,可以满足新的作战样式下大量面向任务需求信息的可靠低时延传输。对全新作战样式下新一代航空数据链的研究具有一定的参考、借鉴意义。

Abstract:

To meet the new network demand of aeronautic swarm operation in the future, a new concept named as “aeronautic swarm cloud network” is proposed, and the coupling mechanism between the communication and mission demand is designed which provides the reference for the concrete technique of aeronautic swarm network. Based on the concept and mechanism, a media access control (MAC) protocol combined with orthogonal frequency division multiple access (OFDMA)-based variable-width channel allocation is designed. The mission demand cognitive mechanism for the proposed protocol is designed in detail, which provides transmission support for intelligent mission planning and decision, the mission demand oriented hierarchical reservation method for channel resource and the greedy reservation algorithm are put forward based on the characteristic of OFDMA and the thinking of mission demand. Simulation results show that the aeronautic swarm cloud network oriented MAC protocol (ASCN-MAC) has a strong advantage in transmission support ability for intelligent mission planning and decision, throughput and real-time. The research has a certain referential significance or value for the new generation of aviation data link research for the new form of operation.
