• An energy-efficient integration of a digital modulator and a Class-D amplifier 

      Zia, M.Y.I.; Tierno, Raúl; Luque-Nieto, Miguel Ángel; Otero-Roth, Pablo (MDPI, 2020-08-16)
      Energy consumption is always a key feature in devices powered by electric accumulators. The power amplifier is the most energy-demanding module in mobile devices, portable appliances, static transceivers, and even nodes ...
    • Optimal Fair Scheduling in S-TDMA Sensor Networks for Monitoring River Plumes 

      Luque-Nieto, Miguel Ángel; Moreno-Roldán, José Miguel; Poncela-Gonzalez, Javier; Otero-Roth, Pablo (Hindawi Publishing Corporation, 2016)
      Underwater wireless sensor networks (UWSNs) are a promising technology to provide oceanographers with environmental data in real time. Suitable network topologies to monitor estuaries are formed by strings coming together ...
    • Optimal scheduling and fair servicepolicy for STDMA in underwater networks with acoustic communications 

      Luque-Nieto, Miguel-Ángel; Moreno-Roldán, José-Miguel; Otero-Roth, Pablo; Poncela-Gonzalez, Javier (MDPI, 2018-02)
      In this work, a multi-hop string network with a single sink node is analyzed. A periodic optimal scheduling for TDMA operation that considers the characteristic long propagation delay of the underwater acoustic channel is ...
    • Self-Organizing and Scalable Routing Protocol (SOSRP) for Underwater Acoustic Sensor Networks 

      Kumar Hindu, Sateesh; Hyder, Waheeduddin; Luque-Nieto, Miguel Ángel; Otero-Roth, Pablo; Poncela-Gonzalez, Javier (MDPI, 2019-07-16)
      Underwater Acoustic Sensor Networks (UASN) have two important limitations: a very aggressive (marine) environment, and the use of acoustic signals. This means that the techniques for terrestrial wireless sensor networks ...
