无人机飞行自组网通信协议

Communication Protocols for UAV Flying Ad-Hoc Network

多无人机协同已经成为当前研究热点,而保证多无人机间快速、可靠的通信是其重要问题之一.基于自组织网络技术提出来的飞行自组网(Flying Ad-Hoc Network,FANET),可为无人机群提供可靠并且实时的网络通信,成为解决多无人机间通信问题的一种良好解决方案.从无人机FANET的节点高动态性和拓扑结构快速变化等特点入手,分析FANET的性能需求;分别从协议设计的挑战、现有协议及其优化协议在FANET的应用现状和专门针对FANET设计的协议发展现状3个方面,对FANET组网通信协议中的多址接入协议、路由协议研究进展进行综述;对无人机FANET的当前重点研究问题和未来研究方向进行了总结和展望.

Multi UAV cooperation has become a research hotspot,and ensuring fast and reliable communication between multi UAVs is one of its important issues.Flying Ad-Hoc Network(FANET)based on ad hoc network technology can provide reliable and realtime network communication for UAV group,and becomes a good solution to solve the communication problems between multiple UAVs.Firstly,this paper analyzes the performance requirements of FANET based on the characteristics of high dynamic nodes and fast topology changes of UAV FANET.Secondly,this paper studies the multiple access protocol and routing protocol of FANET networking communication protocol from three aspects:the challenge of protocol design,the application status of existing protocols and their optimization protocols in FANET,and the protocol development specially designed for FANET.Finally,the current key research issues and future research directions of UAV FANET are summarized and prospected.
