Sensor Networks

 A Wireless Sensor Network (WSN) is a network of autonomous devices with sensing capabilities that are spatially distributed in a given region in order to monitor physical or environmental changes, or detect special events. Sensors of temperature, pressure, acceleration, wind velocity, digital cameras and many others are being extensively used in many  applications (health, industrial monitoring, surveilance, etc).

Sensor Networks state fascinating challenges for research in distributed communication and processing technologies. The activity of G2PI in this application has been devoted to the application of information processing technologies to make sensor more efficient in their use of its resources.

The research activities of G2PI can be classified in the following lines:

  • Distributed parameter estimation:
    • Adaptive networks
    • Combination of local and adaptive systems
  • Decentralized detection systems
    • Optimizing energy resources in censoring sensors
  • Energy-efficient communications
    • Selective communications in harvesting sensors
    • Selective communications in WSN with a finite lifetime.

Most activity is being currently supported by DILEAS project.
