      Conference report
      Restricted access - publisher's policy
      In wireless community access networks, clients tend to reach the Internet through multiple gateway nodes instead of a single default gateway. The mapping of gateways to clients should take into account the perception of ...
    • Community sharing of spare network capacity 

      Dimogerontakis, Emmanouil; Meseguer Pallarès, Roc; Navarro Moldes, Leandro; Ochoa, Sergio; Veiga, Luis (IEEE Press, 2017)
      Conference report
      Restricted access - publisher's policy
      In several community scenarios, people share benevolently their spare broadband Internet access connectivity with other people who cannot afford it. Although laudable, this sharing process can negatively affect the service ...
    • Design trade-offs of crowdsourced web access in community networks 

      Dimogerontakis, Emmanouil; Meseguer Pallarès, Roc; Navarro Moldes, Leandro; Ochoa, Sergio; Veiga, Luis (2017)
      Conference report
      Open Access
      Internet access has become a requirement to participate in society; however, the majority of the world’s population is not yet online. Citizens can self-organize cooperatively to crowdsource community network infrastructures ...
