Abstract:
Nowadays the proliferation of IoT (Internet of Things) devices results in heterogeneous and proprietary sensor data formats which makes challenging the processing and interpretation of sensor data across IoT domains. To achieve syntactic interoperability (the ability to exchange uniformly structured data) is still an issue under research. In this paper, we introduce our purpose developed new script language called Language for Sensor Data Description (L4SDD) to achieve cross-domain syntactic interoperability. L4SDD defines a unified output data format and specifies how the data is to be converted into this format from the various sensor inputs. Besides the language itself, we also present the main features of the workbench created to edit and maintain the scripts and introduce the IoT framework around the solution. The approach provides a high performant, secure and easy-to-use solution to transform their data to an easily processed, self-describing, universal data structure. Althoug
h the paper contains implementation details, the solution can be used in other, similar projects as well. As a practical validation, we also illustrate our solution via a real-life case study.
