    External research report
    Open Access
    Response of 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 themselves– safe ...
  • Improving performance of QUIC in WiFi 

    Manzoor, Jawad; Cerdà Alabern, Llorenç; Sadre, Ramin; Drago, Idilio (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    QUIC is a new transport protocol under standardization since 2016. Initially developed by Google as an experiment, the protocol is already deployed in large-scale, thanks to its support in Chromium and Google's servers. ...
  • Socially aware microcloud service overlay optimization in community networks

    Community networks are a growing network cooperation effort by citizens to build and maintain Internet infrastructure in regions that are not available. Adding that, to bring cloud services to community networks (CNs), ...
  • PiCasso: enabling information-centric multi-tenancy at the edge of community mesh networks 

    Selimi, Mennan; Lertsinsrubtavee, Adisorn; Sathiaseelan, Arjuna; Cerdà Alabern, Llorenç; Navarro Moldes, Leandro (2019-12-09)
    Article
    Open Access
    Edge computing is radically shaping the way Internet services are run by enabling computations to be available close to the users - thus mitigating the latency and performance challenges faced in today’s Internet infrastructure. ...
  • Towards scalable Community Networks topologies 

    Maccari, Leonardo; Gemmi, Gabriele; Lo Cigno, Renato; Karaliopoulos, Merkourios; Navarro Moldes, Leandro (Elsevier, 2019-11)
    Article

    Community Networks (CNs) are grassroots bottom-up initiatives that build local infrastructures, normally using Wi-Fi technology, to bring broadband networking in areas with inadequate offer of traditional infrastructures ...
  • Collaborative informed gateway selection in large-scale and heterogeneous 

    Batbayar, Khulan; Dimogerontakis, Emmanouil; Meseguer Pallarès, Roc; Navarro Moldes, Leandro; Sadre, Ramin (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    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 ...
  • Time series analysis to predict end-to-end quality of wireless community networks 

    Millán Marco, Pere; Aliagas Castell, Carles; Molina Clemente, Carlos Maria; Dimogerontakis, Emmanouil; Meseguer Pallarès, Roc (2019-05-01)
    Article
