dyspanCognitive Wireless Sensor Networks are an emerging technology with a vast potential to avoid traditional wireless problems such as reliability, interferences and spectrum scarcity in Wireless Sensor Networks.

Cognitive Wireless Sensor Networks test-beds are an important tool for future developments,protocol strategy testing and algorithm optimization in real scenarios. A new cognitive test-bed for Cognitive Wireless Sensor Networks is presented in this paper. This work in progress includes the design of both a cognitive simulator for networks with high number of nodes and the implementation of a new platform with three wireless interfaces and a cognitive software for extracting real data.

Finally, as a future work, a remote programmable system and the planning for the physical deployment of the nodes at the university building is presented.

Nowadays, Wireless Ad-Hoc Sensor Networks (WAHSNs), specially limited in energy and resources, are subject to development constraints and difficulties such as the increasing Radio Frequency (RF) spectrum saturation at the unlicensed bands. Cognitive Wireless Sensor Networks (CWSNs), leaning on a cooperative communication model, develop new strategies to mitigate the inefficient use of the spectrum that WAHSNs face. However, few and poorly featured platforms allow their study due to their early research stage.

This paper presents a versatile platform that brings together cognitive properties into WAHSNs. It combines hardware and software modules as an entire instrument to investigate CWSNs. The hardware fits WAHSN requirements in terms of size, cost, features, and energy. It allows communication over three different RF bands, becoming the first cognitive platform for WAHSNs with this capability. In addition, its modular and scalable design is widely adaptable to almost any WAHSN application.

Significant features such as Radio Interface (RI) agility or energy consumption have been proved throughout different performance tests.



SETH – Sistema integral de monitorización estructural de Edificios basado en Tecnologías Holísticas


[Spanish version below]

SETH is the Spanish acromin of “Comprehensive structural monitoring system for buildings based on Holistic Technologies

This project began in early 2013 and will run for two years.

The consortium is composed of: UPM (Technical University of Madrid), CSIC, Isoluz-Corsan, Geocisa and FCC

The objective of this project is:

  • Reduce the impact of vibrations in buildings and people in the environment in which they are founded, through continuous monitoring and quick structural diagnostics.
  • Assess the damage with a high level of accuracy to facilitate decision-making related to the integrity of the building and its need for evacuation and / or rehabilitation.
  • Promote the implementation of the system in the residential area by its easy handling and low cost market.

For this project we are using a set of techniques and devices, some developed in-house and other third parties:

  • Wireless monitoring system of high sensitivity (24 bit) with piezoelectric sensors.
  • Wireless monitoring system of low power MEMS sensors
  • Weather Station PCE-FWS-20


RS – Rehabilitación Sostenible de edificios

  • Title: Rehabilitación Sostenible de edificios (RS)rs
  • Funding Organization: FCC via Centro para el Desarrollo Tecnológico Industrial (CDTI) – Ministerio de Ciencia e Innovación
  • Participants:
    • Research Centers: Universidad de Málaga (UM), Universidad de Sevilla (US), Universidad Politécnica de Madrid (UPM) and Instituto Eduardo Torroja.
  • Description: The main objective of the RS project is the development of an integrated system to achieve an improvement in energy efficiency in the sustainable rehabilitation of existing buildings. Related topics are smart power management, thermal control and renewable energy systems. LSI-B105 at UPM is in charge of monitoring power consumption and temperature at home, gathering user data and preferences and designing energy-efficient strategies for warming the different rooms.
