ContikiHUB

Las Redes de Sensores Inalámbricas (WSN por su nombre en inglés, Wireless Sensor Networks) se encuentran en una fase de rápida expansión por su gran valor en aplicacionescomo la domótica, seguridad o la gestión de recursos en el ámbito industrial. Continuando con la línea de investigación en sistemas operativos (OS) para redes de este tipo recientemente iniciada en el laboratorio, hemos decidido realizar un proyecto que resultará de enorme utilidad a la hora de iniciar el despliegue de una WSN.

ContikiHUB es una plataforma que actúa como pasarela entre los nodos de una WSN que implemente el sistema operativo Contiki e internet. Dado que una WSN emplea distintos protocolos de comunicaciones y medios físicos que los de una red clásica de internet, el objetivo es el de diseñar un hardware capaz de adaptar esos medios físicos para que puedan interconectarse, a la vez que trabajar en el sistema operativo para hacerlo totalmente funcional en dicho hardware y lograr que los protocolos para WSN que utiliza Contiki sean compatibles con los que se emplean en internet.

De esta forma, el resultado final será una plataforma capaz de integrarse por un lado en una WSN (actuando como nodo si es preciso gracias a varios puertos de expansión donde podrán conectarse diversos tipos de sensores) y por otro con un router de una red de internet, pudiendo enviar y recibir datos libremente entre ambas redes.

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.

PFC: Study of wireless nodes as a final product

nodo encapsulado

 

The objective of this project is the study of electromagnetic radiation depending on the final location of the node (in a person, in noisy environments, etc), the electromagnetic compatibility with the environment, applicable law, etc. It will also be important to know the effects of the final case (the one that allows us to obtain a device resistant to the conditions of use) in radiation, range and reliability of the node, as well as possible changes in the behavior of the sensors and actuators in the device, etc.

PFC: Design and implementation of a dynamic Wireless Sensor Network

WSN

The objective of this project is to design and to implement the functionality for different types of nodes that form a wireless network (coordinators, end devices, etc.) to be able to manage their spatial mobility without losing functionality. Nodes must be able to discover new nodes in the network and to dynamically associate to coordinators based on their location. Others parameters like optimal topology and routing network are also sought.
