Unified data model for Wireless Sensor Network

Résumé

The constant evolution of technology in terms of inexpensive and embedded wireless interfaces and powerful chipsets has led to the massive usage and deployment of Wireless Sensors Networks (WSNs). These networks are made of a growing number of small sensing devices and are used in multiple use cases such as home automation (e.g. Smart Buildings), energy management and Smart Grids, crisis management and security, e-Health, entertainment, etc. Sensor devices, generally self-organized in clusters and domain-dedicated, are provided by an increasing number of manufacturers, which leads to interoperability problems (e.g. heterogeneous interfaces and/or grounding, heterogeneous descriptions, profiles, models, etc.). Furthermore, data provided by these WSNs are very heterogeneous because they are coming from sensing nodes with various abilities (e.g. different sensing ranges, formats, coding schemes, etc.). In this paper, we propose a solution for handling WSNs' heterogeneity, as well as easing interoperability management. The solution consists of a semantic open data model for sensor and sensor data generic description. This data model, designed for handling any kind of sensors/actuators and measured data (which is still not the case of existing WSNs data models), is fully detailed and formalized in an original ontology format called "MyOntoSens" and written using OWL 2 DL language. The proposed ontology has been implemented using Protégé 4.3 and pre-validated with Pellet Reasoner. In addition, this original ontology has been pre-qualified through a runner's exercise monitoring application, using in particular SPARQL query language, within a small WBAN platform comprising heartbeat, GPS sensors, and Android mobile phones. Let us finally precise that a Body Area Network (BAN) dedicated instance of the proposed "MyOntoSens" ontology is being standardized as a Technical Specification (TS) within the SmartBAN Technical Committee of the ETSI (European Telecommunications Standards Institute) standardization body
