Study of the credibility of the information shared by a wireless sensor network

The technology of the wireless sensor networks (WSN) is increasingly invading our daily life, taking into account a plenty of existing applications to nowadays (measurements, supervision ...). In many applications of this type of network, the credibility of the information shared by its devices is essentially depending on the criticality of the application. Our goal is to treat the problem of reliability of information exchanged by WSN to make sense of the credibility of this information. The result of this approach is to be able at any moment to give a confidence level to that information exchanged by the WSN. We are implementing a set of mathematical theories to generate an algorithm to characterize the notion of credibility. To validate this study, we conducted a simulation platform.
