Extensible and Precise Modeling for Wireless Sensor Networks

Abstract. Developing applications for wireless sensor networks (WSN) is a complicated process because of the wide variety of WSN applications and lowlevel implementation details. Model-Driven Engineering offers an effective solution to WSN application developers by hiding the details of lower layers and raising the level of abstraction. However, balancing between abstraction level and unambiguity is challenging issue. This paper presents Baobab, a metamodeling framework for designing WSN applications and generating the corresponding code, to overcome the conflict between abstraction and reusability versus unambiguity. Baobab allows users to define functional and non-functional aspects of a system separately as software models, validate them and generate code automatically.
