Wireless sensor network UML profile to support model-driven development

Wireless Sensor Networks (WSNs) are rapidly becoming a necessary tool in many different application areas, such as environmental monitoring, security, safety, and so on. The heterogeneity of hardware is large, so there exists several different environments that support WSN programming. However, the great majority of such environments only target the sensors programming, forgetting about their real intent: the application. In this paper we propose an approach to satisfy the need of high level development methods in WSN applications, aiming to provide a clear link between the modelled WSN constraints and the programming entities. An important part of this proposal is the so-called Wireless Sensor Network (WiSeN) Profile, an UML profile devoted for WSN applications design in a Model-Drivel Development (MDD) paradigm.
