摘　　要：为了解决软件定义无人机自组网(Software-defined Unmanned Aerial Vehicle Ad Hoc Network,SDUANET)中转发黑洞和更新轮次问题,提出了一种软件定义无人机自组网快速一致性更新机制(Software-defined Unmanned Aerial Vehicle Ad Hoc Network Fast Consistent Update Mechanism,SDUANET-FCU)。新机制首先对节点进行分类操作,对可能会导致转发黑洞的发送操作进行约束;其次,针对含有两个规则的节点提出一种基于混合规则的两轮一致性更新策略;最后,将计算得出的Flow-mod发送顺序整合到两轮更新顺序中。仿真结果表明,在软件定义无人机自组网场景下,相比于现有的软件定义网络(Software Defined Network,SDN)更新方法,SDUANET-FCU降低了转发黑洞的概率和控制消息的数量,减少了平均更新轮次。In order to solve the problem of forwarding black holes and update rounds in software-defined unmanned arial vehicle ad hoc network(SDUANET),a fast and consistent update mechanism for SDUANET(SDUANET-FCU)is proposed.The new mechanism first classifies nodes,constrains the sending operations that may lead to forwarding black holes,and then proposes a two-round consistency update strategy based on mixed rules for nodes with two rules.Finally,the Flow-mod send order is integrated into the two-round update order.The simulation results show that in SDUANET scenario,compared with the existing software-defined network(SDN)update methods,SDUANET-FCU reduces the probability of forwarding black holes and the number of control messages,as well as the average update rounds.
