A letter soup for the quality of information in sensor networks

Abstract

In this paper, an information grouping paradigm for Qol in sensor networks is introduced First, a definition of Qol is presented by analyzing the ITU's definition of Q0S Then, the concept of operational context to facilitate the dynamic binding of sensor resources to applications is presented and the 5WH prin ciple ({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. © 2009 IEEE.
