| Abstract: | 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. |
