A novel comprehensive sensor model for cyber physical system: Interoperability for heterogeneous sensor

Any comprehensive Sensor Data Modeling architecture faces the challenges of heterogeneity and proprietary sensor data semantics, which translates into the need for creating optimal semantic transcoders at the sensor gateway level. In this paper a new seven layer sensor modeling approach is presented. The proposed architecture enables us to describe a sensor right from its physical properties to end functionality; where it defines the sensor services to talk with end applications. This approach enables either the low-level software, middleware or Service Oriented Device Architecture (SODA) services to efficiently use the sensor specifications for their individual purposes. In a complex sensory system, the reliability against transient errors in sensor data of a complex sensory system can be provided using a model-based error correction technique comprising of soft sensor data models along with their environmental description. By tightly integrating the operating environment into a sensor description, a generic sensor (like accelerometer) gets redefined as application specific sensor.
