    This paper presents a multi-tenancy model based on infrastructure resource capability virtualisation. The model, namely Resources, Ownership, Roles and Actors or RORA, approaches network and IT infrastructure virtualisation ...
  • An agent-based simulation model of a market for dynamic spectrum access 

    López Berga, Ester; Murcia, César; Beltran, Fernando (2011)
    Conference report
    Restricted access - publisher's policy
    The dramatic increase in the demand for spectrum-based services and devices, combined with the long-term exclusive model of spectrum management, has led to an apparent spectrum scarcity. To overcome this scarcity, the ...

    Open Access
    Covenantee:  University of Auckland
    Català: El gran increment en la demanda de serveis i dispositius que utilitzen l'espectre radioelèctric, juntament amb el caràcter excessiu en termes tant temporals com espacials de les llicenciàs concedides pel seu ús, ...
  • An evaluation of BMX6 for community wireless networks 

    Neumann, Axel; López Berga, Ester; Navarro Moldes, Leandro (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    Conference report
    Restricted access - publisher's policy
    Nowadays, a growing number of communities of citizens build, operate and own open IP-based community wireless networks with thousands of low capacity nodes actively participating in routing the data traffic. This article ...
  • Cloud-based extension for Community-Lab 

    Selimi, Mennan; Florit López, Jorge Luis; Vega d'Aurelio, Davide; Meseguer Pallarès, Roc; López Berga, Ester; Khan, Muhammad Amin; Neumann, Axel; Freitag, Fèlix; Navarro Moldes, Leandro; Baig Viñas, Roger; Escrich, Pau; Moll, Agusti; Pueyo, Roguer; Vilalta, Ivan; Aymerich, Marc; Lamora, Santiago (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report

    P2P based clouds built with low-end devices and voluntarily contributed resources have been proposed by several authors. While some work was published on architectures and decentralized P2P-based mechanisms for such clouds, ...
  • Evaluation of mesh routing protocols for wireless community networks 

    Neumann, Axel; López Berga, Ester; Navarro Moldes, Leandro (2015-12-24)
    Article
    Open Access
    In recent years, we have witnessed the exponential growth of wireless community networks as a response to the clear necessity of Internet access for participation in society. For wireless mesh networks that can scale up ...
  • Forwarding fault detection in wireless community networks 

    López Berga, Ester (Universitat Politècnica de Catalunya, 2017-07-10)
    Doctoral thesis
    Open Access
    Wireless community networks (WCN) are specially vulnerable to routing forwarding failures because of their intrinsic characteristics: use of inexpensive hardware that can be easily accessed; managed in a decentralized way, ...
  • Securely-entrusted multi-topology routing for community networks 

    Neumann, Axel; López Berga, Ester; Cerdà Alabern, Llorenç; Navarro Moldes, Leandro (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Conference report
    Restricted access - publisher's policy
    Routing in open and decentralized networks relies on coopera- tion despite the participation of unknown (alien) nodes and node administrators pursuing heterogeneous trust and security goals. Living use cases for such ...
