      This paper models and evaluates three FSA-based (Frame Slotted ALOHA) MAC (Medium Access Control) protocols, namely, FSA-ACK (FSA with ACKnowledgements), FSA-FBP (FSA with FeedBack Packets) and DFSA (Dynamic FSA). The ...

    • DPCF-M: A medium access control protocol for dense machine-to-machine area networks with dynamic gateways 

      Vázquez Gallego, Francisco; Alonso Zárate, Jesús; Balboteo, Iván; Alonso Zárate, Luis Gonzaga (2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Machine-to-Machine (M2M) area networks must provide connectivity between either an M2M application server or an M2M gateway and a large number of M2M devices. In this paper, we consider a densely populated M2M area network. ...

    • Energy analysis of distributed neighbour discovery algorithms based on frame slotted-ALOHA for cooperative networks 

      Vázquez Gallego, Francisco; Alonso Zárate, Jesús; Alonso Zárate, Luis Gonzaga (2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The design of communications protocols that exploit the availability of both cellular and short-range radio access interfaces in a same terminal can be exploited to improve the energy efficiency of wireless communications ...

    • Energy and delay analysis of contention resolution mechanisms for machine-to-machine networks based on low-power WiFi 

      Vázquez Gallego, Francisco; Alonso Zárate, Jesús; Alonso Zárate, Luis Gonzaga (2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Attaining very high energy efficiency is one of the big challenges to implement Machine-to-Machine (M2M) networks whose lifetime (without human intervention) must be measured in years. In this paper, we consider a synchronized ...

    • Energy harvesting-aware contention tree-based access for wireless machine-to-machine networks 

      Vázquez Gallego, Francisco; Alonso Zárate, Luis Gonzaga; Alonso Zárate, Jesús (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The Energy Harvesting-aware Contention Treebased Access (EH-CTA) protocol is presented in this paper as a novel Medium Access Control (MAC) protocol for wireless Machine-to-Machine (M2M) networks where enddevices are ...

    • Energy harvesting-aware distributed queuing access for wireless machine-to-machine networks 

      Vázquez Gallego, Francisco; Alonso Zárate, Luis Gonzaga; Alonso-Zárate, Jesús (Institute of Electrical and Electronics Engineers (IEEE), 2016)
