摘　　要：拥塞是引起无线多媒体传感器网络(WMSNs)的服务质量(QoS)评价降低的一个重要原因。针对智能实验室WMSNs中的拥塞问题,借鉴业务区分的思想,充分考虑不同类型应用的QoS需求,提出一种基于数据快速转发的QoS保障方法。待转发的数据不再需要完全经过协议栈处理,而是通过学习数据特征建立调度转发规则,其后借助硬件,依据已建立规则处理和转发具有相同特征的数据。实验结果表明,该方法实现了有效提高了节点的转发性能,同时提供了基于业务特征的QoS保障。Congestion is one of the important reasons which caused the quality of service（QoS）evaluation degradation of the wireless multimedia networks（WMSNs）in intelligent laboratory.On account of congestion problems in intelligence laboratory WMSNs,and reference the ideas of business distinguish,fully considering the QoS requirements of different application,proposing a QoS guarantee method which based on fast forwarding data.For forwarding data does not need to through the protocol stack processing completely,but to established scheduling rules by learning the feature of forward data,thereafter with the help of hardware,according to the established rules of processing and forwarding the data with the same characteristics.The experiment result Indicates improve that this method implements effectively improve the performance of forwarding nodes,and provided the QoS guarantee which base on the business characteristics in the meantime.
