Traffic information has multiplied by three its volume market in the last five years. It is also expected that will continue growing greatly in the next years.

However, there are some fields still to be studied and probably exploited regarding traffic information. Such is the case of the integration of both the number of cars and their proper identification.

That is the starting point for the “All in One” project whose objectives are to create an integral traffic monitorization platform with low cost hardware and extended information.

The hardware platform developed will have one radar device for counting vehicles and a Bluetooth interface for identifying them. With this data available and using data integration techniques it will be possible to achieve a level of traffic information yet unknown.

Our group, the B105 Electronic Systems Lab is the one in charge of designing and developing the low-cost radar system. This system includes the electronic for adapting and handling the RF signals as well as the processing modules and digital filters for those signals.

In this project, there are other research groups and some companies involved. As research groups, we are working together with i3-UPM and CEI. The companies we are collaborating with are ACEINSA, KINEO and IPS. This consortium will allow to achieve the project objectives by integrating some partners with expertise in each of the modules of the whole system.

El B105 en el MWC

El B105, con Octavio a la cabeza, realizó una visita a una de las ferias de tecnología más importantes a nivel mundial, el MWC de Barcelona.

El objeto de la visita era conocer, de primera mano, las innovaciones presentes en los desarrollos de las grandes compañias relacionadas con los sistemas embebidos como pueden ser Mediatek, ST Microelectronics, Qualcom, Intel, etc.

Entre los stands que encontramos más interesantes, por estar estrechamente relacionados con la actividad que realizamos en el laboratorio, estuvieron Mediatek, ST Microelectronics y Cadence.

De Mediatek cabe destacar los SoCs fuertemente orientados a IoT en general y wereables en particular. Integraban microcontroladores basados en ARM Cortex M4 con varios interfaces de comunicación inalámbrica como puede ser WiFi, BT y BLE.

ST Microelectronics disponía de un demostrador que plasmaba su interés en aplicaciones de Smart Buildings (de nuevo más IoT) . También presentaba otras mesas donde enseñaba las virtudes y capacidades de cargar dispositivos de forma inalámbrica y los avances desarrollados en este campo como son: mayor distancia a la que se produce la carga y mayor eficiencia en la transmisión de la energía.

En cuanto a Cadence nos llamó la atención el grado de integración de sus diferentes herramientas así como el abanico de posibilidades para el desarrollo de sistemas embebidos que ofrecen. Desde diseño Hardware, hasta su integración con uso de de DSPs y desarrollo para aplicaciones móviles.

A parte e estos stands nos resultó especialmente interesante la alta presencia de la nueva tecnología orientada a las redes móviles 5G, con una aplicación bien lograda en el stand de Nokia. Espectacular el stand de Intel donde asistimos con gran interés a una demostración basada en el uso del proyecto de Google Project Tango.

Y por último el stand de BQ donde pudimos tocar y utilizar su último móvil BQ Aquaris X5 Plus. Nos pareció un móvil muy completo y maduro que no hace más que afianzar a la empresa española entre las grandes de la telefonía móvil.

Finalización del proyecto DAMAS: desarrollo de un sistema automático de monitorización inalámbrico para grandes presas

Damas_CdTi

 

El proyecto DAMAS llega a su finalización y justificación y el pasado 1 de Octubre de 2015 se celebró una reunion con el Centro para el Desarrollo Tecnológico Industrial (CDTi) para mostrar los resultados de los desarrollos llevados a cabo.

Este proyecto ha sido cofinanciado por el Fondo Europeo de Desarrollo Regional, FEDER, dentro del Programa Operativo de la Comunidad de Madrid 2007-2013 (Unión Europea).

Durante la reunión llevada a cabo se hicieron dos presentaciones y demostraciones, mostrando los resultados. Una era relativa a la parte de los desarrollos electrónicos y de equipos. En esta parte el B105 Electronic Systems Laboratory hizo una demostración del funcionamiento de los nodos inalámbricos desarrollados. La demostración fué autoexplicativa y se fué guiando a los asistentes a través del proceso que seguiría la detección de un evento físico en la presa. Esto es, el accelerómetro proporciona modificaciones de la tensión en función a sus aceleraciones. Esas aceleraciones se transforman y almacenan como datos de 24 bits. Y por ultimo tramas de bits se transmiten aun nodo central que las procesa.

La segunda parte de la presentación fué llevada a cabo por la escuela de Caminos que eran los responsables de explicar como se procesan los datos y que información se puede extraer de los mismos. De esta forma y con los datos reales tras monitorizar la presa, es posible calibrar el modelo teórico.

Title: Cognitive Test-bed for Wireless Sensor Networks

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.

Cognitive Wireless Sensor Network Platform for Cooperative Communications

Title: Cognitive Wireless Sensor Network Platform for Cooperative Communications

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.
