    Community wireless mesh networks have emerged as cooperative initiatives to provide Internet Access in areas where traditional ISP costs are not affordable for the population. It is common in wireless mesh networks sharing ...
  • A LoRa-Based communication system for coordinated response in an earthquake Aftermath 

    Pueyo Centelles, Roger; Freitag, Fèlix; Meseguer Pallarès, Roc; Navarro Moldes, Leandro; Ochoa, Sergio; Santos, Rodrigo M. (MDPI, 2019)
    Conference report
    Open Access
    The response conducted by emergency units after natural disasters, such as earthquakes, has to be coordinated, fast, and efficient in order to rescue and care for the victims, keeping all the population—and the units ...
  • GateSelect: A novel Internet gateway selection algorithm for client nodes 

    Batbayar, Khulan; Meseguer Pallarès, Roc; Sadre, Ramin; Subramaniam, Suresh (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    The Internet gateway selection problem is becoming very important as the number of Internet-connected devices increases and stresses the limited number of Internet gateway nodes. The gateway nodes often experience frequent ...
  • MeshDapp: Blockchain-enabled sustainable business models for networks

    Conference report
    Open Access
    The Guifi.net community network has evolved during the past 15 years into a telecommunications infrastructure that offers Internet access to more than 80.000 people. The monitoring system currently in place for this network ...
  • End user-managed service deployments in microclouds at the network edge 

    Freitag, Fèlix; Navarro Moldes, Leandro; Selimi, Mennan; Pueyo Centelles, Roger (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    Cloud computing is moving from data centers to the network edge. Edge computing introduces lightweight computing devices closer to where data are produced. Local processing enables faster response times for cloud-based ...
  • A monitoring system for distributed edge infrastructures with decentralized coordination 

    Pueyo Centelles, Roger; Selimi, Mennan; Freitag, Fèlix; Navarro Moldes, Leandro (Springer, 2019)
    Conference report
