    This paper provides design guidelines in the feasibility and deployability of nanonetworks powered by energy harvesting techniques throughout bounding the per node throughput capacity as a function of the number of nodes. ...
  • Graphene-enabled wireless networks-on-chip 

    Llatser Marti, Ignacio; Abadal Cavallé, Sergi; Mestres Sugrañes, Albert; Cabellos Aparicio, Alberto; Alarcón Cot, Eduardo José (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Conference report
    Restricted access - publisher's policy
    Graphene-enabled Wireless Communications (GWC) advocate for the use of graphene-based plasmonic antennas, or graphennas, which take advantage of the plasmonic properties of graphene to radiate electromagnetic waves in the ...
  • Initial MAC exploration for graphene-enabled wireless networks-on-chip 

    Piro, Giuseppe; Abadal Cavallé, Sergi; Mestres Sugrañes, Albert; Alarcón Cot, Eduardo José; Solé Pareta, Josep; Grieco, L. Alfredo; Boggia, Gennaro (Association for Computing Machinery (ACM), 2014)
    Conference report
    Restricted access - publisher's policy
    In the upcoming many-core era, chip multiprocessor architectures will be composed of hundreds or even thousands of processor cores, which interact among them through an on-chip communication platform for synchronization ...

    Abadal Cavallé, Sergi; Mestres Sugrañes, Albert; Llatser Marti, Ignacio; Alarcón Cot, Eduardo José; Cabellos Aparicio, Alberto (Association for Computing Machinery (ACM), 2015)
    Conference report
    Restricted access - publisher's policy
    Graphene-based antennas (or shortly named, graphennas) are envisaged to be the cornerstone of novel wireless communication systems by virtue of their reduced size, in the micrometer range, and an expected radiation frequency ...
  • Towards a NetFlow implementation for OpenFlow software-defined networks 

    Suárez-Varela Maciá, José Rafael; Barlet Ros, Pere (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference report
    Open Access
    Obtaining flow-level measurements, similar to those provided by Netflow/IPFIX, with OpenFlow is challenging as it requires the installation of an entry per flow in the flow tables. This approach does not scale well with ...
