摘　　要：随着通信网络不断向各领域延伸,飞行自组网作为一种新型移动自组织网络,以飞行器作为空中无线通信节点建立网络,实现网络层高效通信。首先,通过考虑链路质量、流量负载和空间距离构建多路径路由模型,并设计抗干扰的多路径路由算法;其次,构建基于源节点路由回复包接收速率的解析模型;然后,对模型进行分析与评价;最后,通过仿真实验验证所提出路由协议的效能。仿真结果表明,所提出的协议与传统协议相比,当节点数相同时,数据包传递率可提升约4.04%~12.13%;干扰器数量为6时,数据包传输延迟可提升约38.48%~52.53%,并且端到端通信中断率降低约34.54%~41.67%,在各项性能指标中都具备优势。所提出的抗干扰多路径路由协议可以为飞行器提供有效且可靠的通信数据传输,并在存在恶意干扰的情况下为飞行自组网提供网络弹性保证。未来将考虑更复杂的链路情况,使其具有更大的实际应用价值。As a result of the rapid technological advances on communication technologies, it has been possible to form a Flying Ad hoc Network, which can use aircraft as the wireless communication node to establish the network and realize efficient communication. Firstly, the design of multipath routing model is based on three major schemes that are link quality, traffic load and space distance and anti-jamming multipath routing algorithm is designed. The analytical model of route reply packet reception rate of source node is built and its numerical result is analyzed. Finally,anti-jamming routing protocol is evaluated through simulation experiments. The simulation results show that anti-jamming routing protocol can not only increase packet delivery ratio by 4.04%~12.13% when the number of nodes on the network is the same and increase packet delivery latency by 38.48%~52.53% but also can reduce end-to-end communication outage rate by 34.54%~41.67% when the number of jammers is same. In order to solve application requirements and link vulnerability of Flying Ad hoc Network, an anti-jamming routing protocol in this paper is proposed to provide reliable communication and overall network performance. In the future, more complex link cases will be considered to make it have greater practical application value.
