Abstract

In recent years, Wireless Sensor Networks (WSNs) have been primarily used to build ad-hoc telecommunication infrastructures from scratch or as low-cost alternatives to traditional networks. But the diversity of applications with typically narrow node resources and requirements of already existing information infrastructures sets hard constraints to WSN. The software development process becomes even more complicated when real-time constraints have to be taken into account. This is the case when the physical processes of the WSN environment have to be observed and are realized in space and time. For the development of such WSN we present a model-based framework (GAF4WSN), where the wellknown techniques SDL, UML and ASN.1 are involved. The framework was already successfully used for the development of a new generation of Earthquake EarlyWarning Systems (EEWS). An Earthquake Synthesizer (ES) and an ExperimentManagement System (EMS) complete the framework, which supports themodelling, simulation, installation and administration of different EEWS approaches in combination with a Geographic Information System (GIS).
