Evaluation and monitoring of wireless community networks

En les darreres dècades s’han produït molts canvis en l’àmbit de les telecomunicacions, gran part d’aquest canvi ha estat propiciat per l’aparició d’Internet, la “xarxa de xarxes” capaç de connectar usuaris a gairebé qualsevol punt del món. Inicialment totes les infraestructures eren cablejades, però en els darrers anys ha anat avançant l’electrònica permetent reduir la mida dels dispositius terminals. Això ha afavorit i facilitat la mobilitat d’usuaris amb els seus terminals, pel que les tecnologies inalàmbriques han evolucionat conjuntament per oferir-los connectivitat. Diversos projectes per tot el món han aparegut amb l’objectiu de desplegar xarxes inalàmbriques obertes creant comunitats d’usuaris, empreses i entitats; l’exemple més proper a Catalunya és la fundació Guifi-net. Degut a la dificultat d’administrar aquest tipus de xarxes ja que són completament obertes i qualsevol usuari s’hi pot afegir lliurement, l’objectiu d’aquest projecte és proporcionar orientació i eines per tal de fer-ho. Altres factors com l’entorn poden alterar el correcte funcionament de la xarxa degut al medi inalàmbric, això en complica encara més la gestió. Amb totes les eines i mesures descrites dins d’aquest projecte, un administrador d’una nova xarxa inalàmbrica comunitària seria capaç d’avaluar l’estat d’aquesta i, així, mantenir i millorar el seu rendiment. English: In the last decades there have been many changes in the telecommunications sector, much of this change has been brought by the creation of the Internet, the "network of networks" that can connect users to almost any point in the world. Initially all infrastructures were wired, but in recent years electronics has advanced allowing to reduce the size of the terminal devices. This has encouraged and facilitated the users' mobility with their terminals, so wireless technologies have evolved together to offer connectivity. Several projects around the world have emerged with the aim of deploying open wireless networks composed by user communities, companies and organizations; the closest example in Catalonia is the Guifi-net foundation. Due to the difficulty of managing such networks because they are completely open and anyone can freely joain, the aim of this project is to provide guidance and tools to do so. Other factors such as the environment can alter the proper functioning of the network due to the wireless medium, it further complicates the management. With all the tools and measures described within this project, a new wireless network administrator of a community would be able to evaluate its status and maintain and improve their performance

LEGaTO: first steps towards energy-efficient toolset for heterogeneous computing

LEGaTO is a three-year EU H2020 project which started in December 2017. The LEGaTO project will leverage task-based programming models to provide a software ecosystem for Made-in-Europe heterogeneous hardware composed of CPUs, GPUs, FPGAs and dataflow engines. The aim is to attain one order of magnitude energy savings from the edge to the converged cloud/HPC.Peer ReviewedPostprint (author's final draft

LEGaTO: Low-energy, secure, and resilient toolset for heterogeneous computing

The LEGaTO project leverages task-based programming models to provide a software ecosystem for Made in-Europe heterogeneous hardware composed of CPUs, GPUs, FPGAs and dataflow engines. The aim is to attain one order of magnitude energy savings from the edge to the converged cloud/HPC, balanced with the security and resilience challenges. LEGaTO is an ongoing three-year EU H2020 project started in December 2017.This project has received funding from the European Union Horizon 2020 research and innovation programme under the LEGaTO Project(legato- project.eu), grant agreement No 780681.Peer Reviewe
