Quality of Information: An Empirical Approach

In this paper the authors examine the Quality of Information (QoI) at the output of a wireless sensor network by considering the difference between the monitored environment and the interpreted data produced by the network. Using practical examples in an experimental setting, they hope to shed light on the concept of QoI and on the manner of estimating and evaluating it. The authors use a real wireless network in combination with simulated events, to help people to formulate and understand the concept of QoI and its associated technical questions.
