An intelligent sensor network for distributed data rectification and process monitoring

Sensor networks are a key technology for the 21st century. Our research aims to formulate and implement a new conceptual model for the next generation of networked sensor devices, which encompasses not only intelligence in local sensor nodes such that the sensors are self validating, but also the additional capability that the sensors could be networked and communicate with one another and share information. The basic idea is to decompose the processing of monitoring and data rectification tasks and decentralize them on a federated sensor network. The proposed framework has been implemented for a chemical process unit. Experiment results demonstrated the feasibility and thus, the potential of the proposed sensor network.
