One of the approaches to reduce the complexity of application adaptation for a particular sensor network installation is to separate the application completely from the information acquisition level of the sensor network. However, in this case the question arises if the information obtained is good enough for the application. In this paper we describe the possible metrics of information quality (IQ)...
To satisfy application information quality (IQ) constraints in a sensor network, the efficient way is to choose the most appropriate sensor nodes and sensor modalities which would provide a required IQ for the current state of the system. In this paper, two formulations of an activity recognition application are considered - the first based on static Bayesian network (BN), and the second on dynamic...
