IEEE1451 standard in wireless sensor networks using TinyOS message abstractions

This poster describes the IEEE1451 message structure of some commands and transactions using the TinyOS basic network abstractions. The network is composed by one base station namely Network Capable Application Processor (NCAP) and several Wireless Transducer interface Modules (WTIMs). The messages are transmitted between the NCAP and each WTIM. We propose the use of the general message structure IEEE1451 with ZigBee and 6loWPAN interfaces using the TinyOS packet protocols to improve the interoperability of heterogeneous smart sensor nodes. Tests are conducted to evaluate the implementation of the IEEE1451 standard and determinate the complexity of the transactions and alternative methods for energy management.Peer ReviewedPostprint (published version

On the feasibility of Bluetooth, Zigbee and IEEE 802.15.4 technologies on board high speed trains

This paper studies the feasibility of using low-power wireless technologies such as Bluetooth, IEEE 802.15.4 and ZigBee in high-speed railway scenarios that involve bidirectional land-to-train communication. The presented results have been obtained through experimental tests conducted at the high-speed railway line connecting Madrid to Barcelona. A multiplatform communication system has been installed in a high-speed train, circulating at velocities up to 300 km/h, whereas autonomous devices have been disseminated along of the railway path to communicate with the onboard devices. The conclusions drawn from this work will be used as guidelines for the future implementation of autonomous communication platforms for high-speed rail connectivity.Postprint (author’s final draft

Tiny and autonomous IEEE1451 Sonic Anemometer to deploy in environmental Wireless Sensor Network

Wind speed and direction are important parameters in the study of applied meteorology, for example, in weather prediction, air pollution, transport safety and structural safety. In this paper, we propose the design and deployment of an interoperable Smart Ultrasonic Anemometer that uses the IEEE 1451 standard and operates in a Wireless Sensor Network (WSN). This standard permits interoperability and introduces self-calibration and self-configuration tasks. We include power management considerations to calculate the energy consumption using a low power sampling protocol BMAC with variable duty cycle. Experimental tests are included to study the current consumption using an energy harvester with solar panel and super capacitors to increase the reliability and lifetime of the sensor node.Peer ReviewedPostprint (published version
