      Montejo Sánchez, Samuel; Azurdia Meza, César; Souza, Richard Demo; García Fernández, Evelio; Soto, Ismael; Rebelatto, João Luiz (IEEE, 2017)
      Some of the future wireless networks are related tothe provision of higher data rates and lower energy consumption.In contrast to the clear increasing spectrum demand, bandwidthis a limited resource. Cooperative ...
    • Direct-to-satellite IoT slotted aloha systems with multiple satellites and unequal erasure probabilities 
      Tondo, Felipe Augusto; Montejo Sánchez, Samuel; Pellenz, Marcelo Eduardo; Céspedes Umaña, Sandra Lorena; Souza, Richard Demo (MDPI, 2021)
      Direct-to-satellite Internet of Things (IoT) solutions have attracted a lot of attention from industry and academia recently, as promising alternatives for large scale coverage of a massive number of IoT devices. In this ...
    • Dynamic control of beacon transmission rate with position accuracy in vehicular networks 
      Bolufé, Sandy; Montejo Sánchez, Samuel; Azurdia Meza, César; Céspedes, Sandra; Souza, Richard Demo; Fernández, Evelio M. G. (CEUR-WS, 2017)
      The proper performance of cooperative safety applications in vehicular networks depends of the exchange of beacon messages between neighboring vehicles. A challenge in these networks is to control the beacon transmission ...
