摘　　要：针对海域无人机集群组网监测过程中的网络间动态通信问题,从路由选择、高动态随机接入、动态资源调度等方面研究了无人机集群组网通信的关键技术。设计分簇DSDV(Destination sequenced distance vector routing)路由选择协议,按照任务类型需求为各簇动态分配网络带宽,改善网络性能;设计按需分配的分布式高动态随机接入协议、基于比例公平算法的动态资源管理方法,解决无人机集群子节点在接入和退出时产生的不确定性问题,有效避免在通信过程中出现多个接入请求冲突的问题。结果表明,利用文中提出方法设计的组网通信终端,各项指标与集群通信需求相比均有较大余量,能够满足海域无人机集群组网通信要求。Considering the dynamic communication processing between networks when monitoring UAV(Unmanned aerial vehicle)cluster network in marine application scenario,the key technologies of UAV cluster network communication is studied,from the aspects of routing,high dynamic random access and dynamic resource scheduling.A clustering DSDV(Destination sequenced distance vector routing)routing protocol is designed,which dynamically allocates network bandwidth to each cluster according to the requirements of task types,so as to improve the network performance.Apart from this,a distributed high dynamic random access protocol with on-demand distribution and a dynamic resource management method based on proportional fairness algorithm are designed,to solve the uncertainty problem of UAV cluster sub-nodes when accessing and exiting,and effectively avoid the conflict of multiple access requests in the communication process.The results show that the networking communication terminal designed by this method has a large margin compared with the cluster communication requirements,and can meet the requirements of UAV cluster communication in the sea area.
