Challenges of simulating robust wireless sensor network applications in building automation environments

Wireless sensor networks (WSN) get increasing importance in different application areas. In building automation, applications on WSN are expected to utilize a large number of nodes in a heterogeneous environment. They are too complex to be developed in the traditional way of prototyping and debugging. In fact, new techniques are needed to support the design of WSN applications efficiently. Simulation is one important method to decrease design time and to increase design quality. This is crucial for applications in building automation because very high reliability and robustness are required. In this paper major challenges of simulating wireless sensor network applications are discussed. Using a WSN simulation framework, functional simulation and the evaluation of robustness of WSN applications in building automation environments are demonstrated.
