A model-based transformation framework for designing and analyzing wireless sensor networks

Abstract

Wireless sensor networks (WSNs) comprise resource-constrained (e.g., memory, processing, and energy) sensornodes that are deployed in different areas and are able to monitor environmental conditions. Simulation has been widelyused in order to evaluate the network performance. In this context, software designers need to evaluate, refine, andvalidate high-level models for WSN applications at early stages of development via simulation tools, in particular forWSN applications supporting energy-harvesting devices. In the present paper, we propose a model-based transformationframework that allows the modeling and simulation of a WSN system supporting energy-harvesting capabilities. Inthis proposal, we start from a high-level specification based on the UML/MARTE profile, which describes an energyharvesting WSN node. Then a model-to-text (M2T) transformation allows us to generate simulation scripts for analysispurposes by focusing on energy consumption.
