ABSTRACT
Models play an important role in many different disciplines. The broad scope of applicability of models results in a wide range of types of models for a given system component, a range of system components that are of interest to be modeled, and an assortment of levels of detail provided in models. We introduce a classification system for models of networked embedded systems such as sensor networks, provide a taxonomy of existing research on models in terms of the presented classification framework, and highlight example applications of models in the research literature. Based on the insight gained in developing the classification framework and taxonomy, we discuss possible future modeling directions in the area of wireless sensor networks.
