Ubiquitous architecture for environmental sensor networks in road traffic applications

The widespread use of electronic equipments and their integration into the vehicular system have become a necessity in the automobile industry. The Smart Transducer concept -along with IEEE Standard 1451- improves the scalability of these networked electronic devices into a vehicular system. This paper describes the design and implementation of a real-time environmental wireless sensor network that characterizes air quality in Asuncion, Paraguay. Mobile sensor devices in public transport vehicles provide an effective mechanism to develop an efficient solution for this characterization. The development of the sensor network is presented, and experimental results obtained for the characterization of the proposed environmental monitoring system are provided.
