Abstract
En la actualidad se están realizando un gran número de proyectos de investigación relacionados con las redes multisalto inalámbricas. La mayoría de estos trabajos se han centrado tradicionalmente en estudios teóricos y/o de simulación, por lo que es necesario avanzar en la línea de plataformas experimentales que permitan validar los resultados teóricos y probar nuevos diseños y algoritmos. El enfoque que se le da a estos proyectos, en la mayoría de los casos, motiva la creación de plataformas de pruebas, desarrolladas tanto en interiores como en exteriores. Estas redes de pruebas, que requieren una significativa cantidad de recursos a la hora del despliegue y el mantenimiento, se utilizan para llevar a cabo medidas con el fin de analizar y entender las limitaciones y diferencias entre los resultados de los análisis o simulaciones y los obtenidos en experimentaciones reales. En este proyecto se realizan dos importantes aportes bastante novedosos; en primer lugar se describe un innovador banco de pruebas multisalto inalámbrico, el cual se desarrolla y se opera bajo el suelo de un laboratorio de la universidad. Este falso suelo proporciona una protección frente a otras señales inalámbricas, gracias a las características que poseen los paneles del suelo (durante el desarrollo del proyecto se estudiará más a fondo esta particularidad). Por otra parte, realizando experimentos controlados, hemos sido capaces de analizar al límite el comportamiento de dispositivos comerciales, así como observar criterios de diseños prácticos para el desarrollo de redes inalámbricas mesh. Los resultados que hemos obtenido en las experimentaciones de este proyecto, caracterizan los dispositivos inalámbricos utilizados, sientan las bases para futuros experimentos que los empleen y nos permiten obtener conclusiones importantes a la hora de realizar futuros experimentos en esta plataforma u otras similares. _____________________________________________________________________________________________________
Currently, a lot of researches related with multihop wireless networks are being carried out. Most of these projects are focused on theoretical researches and/or simulations, so new experimental testbeds that allow to validate theoretical results and try new algorithms are needed. The approach to these projects, in most cases, motivates the testbeds, developed both inside and outside. These testbeds require a lot of resources in the deployment and maintenance, and are used to carry out measurements to analyze the limitations and differences between the results from analysis or simulations and the ones obtained in real experimentation. In this project two innovate important contributions are carried out; first an innovate wireless multhop testbed is described. This testbed is developed and operated under the false floor of lab of a university building. This false floor provides a strong physical against another wireless signals thanks to the false floor panels characteristics (this aspect will be more developed later). Second, by running controlled experiments we are able to analyze the performance limits of commercial devices, as well as to derive practical design criteria for the deployment and configuration of mesh networks. The results obtained in the experimentations characterize the wireless devices used, lay the foundations for future tests with these devices and allow us to extract important conclusions from the experiments realized.
