A letter soup for the quality of information in sensor networks

In this paper, an information grouping paradigm for QoI in sensor networks is introduced. First, a definition of QoI is presented by analyzing the ITU's definition of QoS. Then, the concept of operational context to facilitate the dynamic binding of sensor resources to applications is presented and the 5WH principle ({why, when, where, what, who, how}) for summarizing the information needs of an application and the capabilities of the sensing resources is introduced. Finally, a brief treatise on metrics composition for relevancy parameters is presented.
