摘　　要：媒体数据的引入使得对无线多媒体传感器网络(WMSNs)的信息质量进行定性和定量评估更为复杂.针对WMSNs中多种类型数据的不同特点,联合网络质量评估和数据质量评估,构建无线多媒体传感器网络信息质量综合评估模型,并提出信息质量综合评估指标体系.首先,根据WMSNs业务特点定义综合评估指标体系的各项评估指标;其次,针对综合评估模型中的网络评估和数据评估,定义了网络域和数据域各评估参数的计算方法;最后,给出了综合评估体系中各项评估指标的综合评测方法.In wireless multimedia sensor networks（ WMSNs）,multimedia data makes both qualitative and quantitative assessment for information quality more complex. Taking various types of data into account,a comprehensive assessment system which combines assessment of network quality and data quality to build a whole assessment model for WMSNs is established. First,the evaluating indicators are clearly defined according to the distinctive service provided by WMSNs. Second,the specific calculation method is analyzed for each parameter in both network domain and data domain according to the assessment of network and data. Finally,the integrated assessment scheme which consists of the evaluating of all indicators is proposed.
