摘　　要：以MUAV战术通信中继应用场景为模型,对战场中存在的各种不同的业务类型有针对性的采用优先级转换策略及流量聚合机制进行动态带宽分配。该方法参考了IEEE 802.11p分类标准并建立了该标准与WME的等价关系。试验发现,流量聚合机制和"插队"机制的引入,能显著提高系统节点的吞吐量,并降低节点的传输时延。实验证明,该动态带宽分配方法能够有效优化带宽分配,降低系统延时(20 ms以下),更好地达到无人机战术中继网络的要求。To model the MUAV communication relay in tactical conditions,a variety of different business types targeted by priority transformation strategy and flow aggregation mechanism for dynamic bandwidth allocation was proposed.This method referenced for IEEE 802.11 p classification standards and the standard with WME equicalence relation was established.The study found that the polymerization mechanism and the introduction of＂jumping the queue＂could significantly improve the throughput of system node,and reduce the transmission delay of nodes.The experiments showed that the dynamic bandwidth allocation method could effectively optimize the bandwidth allocation,reduce the delay of the system（under 20 ms）and better meet the needs of MUAV tactical relay network.
