针对战术环境下微小型无人机通信中继平台的应用,提出了一种具有业务类型发现能力的动态带宽分配方法,构建了符合战术应用场景的业务类型分类,引入流量聚合机制、业务类型发现机制和“插队”特权,完成了带宽的动态分配。实验表明,基于业务类型发现的动态带宽分配方法能够有效提升“热点”节点的吞吐量,降低“紧急”节点的传输时延,较好地满足了战术应用要求。
Aiming at the application of tactical environment for the miniature UAV communication relay platform, this paper proposes a dynamic bandwidth allocation method with service type discovery capability, constructs the service type classification according to the tactical application scenario, introduces the traffic aggregation mechanism, the service type discovery Mechanism and “queue ” privilege to complete the dynamic allocation of bandwidth. Experiments show that the dynamic bandwidth allocation method based on service type discovery can effectively increase the throughput of hot spots and reduce the transmission delay of the emergency nodes, which meets the requirements of tactical application well.
