Application-Oriented Fusion and Aggregation of Sensor Data

A glance at the today’s research and industry community shows that AAL installations are normally offered as “complete solutions”, often including overlapping of almost equal or homogeneous sensors. Thus, redundant sensors are integrated in one single space when purchasing different AAL solutions, leading to an increase of acquisition costs and higher data volume. In order to counteract this problem, we present a method for application-oriented fusion and aggregation of sensor data. Here, the main contribution is a reference model and a semi-automatic approach for the determination of applicability of sensors to predefined AAL applications.
