摘要: 为了制定无线航空电子内部通信(WAIC)网络协议,参考网络通信5层协议模型、机载有线通信网络可靠性安全性要求、工业无线网络协议及WAIC网络最新研究成果,提出了WAIC网络系统模型,包括应用模型、拓扑模型和通信协议模型,并对WAIC网络通信协议各层技术难点和解决方法进行了深入的研究.物理层使用4.2~4.4 GHz频段,通过正交频分复用技术提高抗干扰能力,高低速分别选用正交振幅调制和正交相移键控编码方式;数据链路层使用被动式邻居发现策略、时分多路访问调度方式和主备信道传输机制;网络层使用静态图路由协议,提供一次链路故障冗余;传输层使用无连接传输服务,基于双向认证的接入控制以及数据加密机制;应用层使用匿名消息签署协议将应用与网络解耦,提高WAIC网络应用模式的多样性和兼容性.

Abstract: In order to develop the wireless avionics intra-communications(WAIC) network protocol, referring to five layer protocol model of network communication, the reliability and security requirements of airborne wired communication network, the industrial wireless network protocol and the latest research results of WAIC network, the WAIC network system model is given. The application model, the topology model, the communication protocol model, and the technical difficulties of each layer of WAIC network communication protocol are analyzed as the key points and solutions. The physical layer uses 4.2~4.4 GHz frequency band, improves the anti-interference ability through orthogonal frequency division multiplex-ing technology, and selects quadrature amplitude modula and quadrature phase shift keying coding mode for high and low speed respectively; The data link layer uses passive neighbor discovery strategy, time division multiple access scheduling mode and active/standby channel transmission mechanism; The network layer uses static graph routing protocol to provide primary link fault redundancy; The transmission layer uses connectionless transmission service based on bidirectional identification; The application layer uses anonymous subscriber messaging protocol to decouple the application from the network to improve the diversity and compatibility of WAIC network application scenarios.
