Fusión de datos en redes de sensores: una revisión del estado del arte

El documento presenta una revisión de literatura en el contexto de redes de sensores y fusión de datos, el cual expone una breve descripción de algunas implicaciones importantes de las redes de sensores y las técnicas que frecuentemente se han usado como alternativa de solución ante los desafíos habituales en las principales topologías de las redes. De igual manera se efectúa una  orrespondencia entre los modelos que se han propuesto hasta la fecha y que comúnmente se han tomado como referencia para implementar un sistema de fusión de datos a fin de identificar el enfoque primordial de cada uno de estos. Finalmente se realiza una descripción de aportaciones dirigidas a sensores inteligentes, dejando claro que se requiere más investigación en este contexto que permitan formular soluciones viables a las problemáticas actuales en dicha área de aplicación.AbstractData fusion in sensor networks: a review of the state of the artA literature review in the context of sensor networks and data fusion is presented as a brief description of some important implications for sensor networks and the techniques that have been frequently used as an alternative solution in the common challenges of main network topologies. Also, this paper presents a correspondence between the models that have been proposed and have been frequently used as a reference to implement a data fusion system. Finally, there is a description of contributions aimed towards smart sensors, emphasizing the need of more research in this context to help formulate viable solutions to the current problems in this area of application. Keywords: data fusion, wireless sensor network, network topology, model, smart sensor.

Challenges in developing a generic monitoring framework for pan-European energy usage and environmental monitoring

The ability to easily monitor different aspects of the environment is essential to achieve the aspirations of smart homes, smart buildings and smart cities across Europe. A wide range of sensors are available for both the domestic and commercial markets to enable different aspects of the environment to be monitored. These sensors are disparate, requiring different interfaces and utilizing conflicting data formats. This paper reports on the development of a generic monitoring framework to capture and analyse data from ubiquitous sensing devices in smart cities. The framework has been tested by capturing energy usage data from both public and commercial buildings, and domestic homes in three cities across two European countries. Dashboards were created to enable facility managers and home owners to compare energy usage with similar buildings in different cities. The paper discusses the technical and data quality challenges encountered with capturing data from domestic and non-domestic buildings and highlights the need for a generic context framework to support monitoring and analysis of the pan-European data captured
