软件定义的无人机网络架构研究综述

软件定义网络（Software Defined Network，SDN）依靠着其集中控制、可编程性和数控分离等优点，能够有效解决无人机网络（Flying Ad Hoc Network，FANET）面临的任务拓扑高度变化、网络链路连接不稳定、网络安全防护脆弱以及应用程序的异构性等问题，极大地提升FANET的灵活性和可靠性。针对SDN架构与FANET的结合问题，描述了SDN的体系架构，并以SDN控制器部署方式为关注点分类别概括了近几年软件定义无人机网络（Software-defined Flying Ad Hoc Network，SD-FANET）的研究进展，重点阐述了结合移动边缘计算（Mobile Edge Computing，MEC）的SD-FANET研究现状，最后指出了SD-FANET的应用场景和一些具体的未来研究方向。

Survey on SDN architecture in flying ad hoc network(FANET)

Relying on its advantages of centralized control,programmability,and separation of data plane and control plane,software defined network(SDN) can effectively solve the problems of highly variable task topology,unstable network link connection,fragile network security protection,and heterogeneity of applications faced by the flying ad hoc network(FANET) and greatly improve the flexibility and reliability of FANET.For the combination of SDN architecture and FANET,the architecture of SDN is described.The research progress of software-defined flying ad hoc network(SD-FANET) in recent years is summarized with the focus on SDN controller deployment method,and the research status of SD-FANET combined with mobile edge computing(MEC) is emphasized.Finally,the application scenarios of SD-FANET and some specific future research directions are pointed out.
