    • Serban, Ioan; Céspedes Umaña, Sandra; Marinescu, Corneliu; Azurdia Meza, César; Gómez, Juan S.; Sáez Hueichapán, Doris (IEEE, 2020)
      Progress in Microgrid (MG) research has evolved the MG concept from classical, purely MG power networks to more advanced power and communications networks. The communications infrastructure helps control and manage the ...
    • Serban, Ioan; Céspedes Umaña, Sandra; Marinescu, Corneliu; Azurdia Meza, César; Gómez Quintero, Juan; Sáez Hueichapan, Doris (IEEE, 2020)
      Progress in Microgrid (MG) research has evolved the MG concept from classical, purely MG power networks to more advanced power and communications networks. The communications infrastructure helps control and manage the ...
    • González Mendoza, Maite; Holloway, Benjamín; Hevia Angulo, Alejandro; Céspedes Umaña, Sandra; Bustos Jiménez, Javier (CEUR-WS, 2017)
      In order to minimize the accidents, autonomous vehicles are being designed as the future of transportation. To fulfill this goal, we should look at vehicular intersections, where unfortunately most car accidents take place. ...
    • Salamanca, Juan; Céspedes Umaña, Sandra; Vinasco, Daniel; Yáñez, Alexis (IEEE, 2017)
      Innovative solutions for smart transportation involve the integration of communication technologies, mobile applications, control mechanisms, and human-to-machine interfaces. In this demo we present the prototype of a ...
    • Céspedes Umaña, Sandra (2018)
      Network-layer mobility management refers to the ability of a mobile node to maintain the IP address while it moves. In traditional IP networks, IP addresses are employed at the same time as host identifiers and locators. ...
    • Montejo Sánchez, Samuel; Azurdia Meza, César; Bolufé, Sandy; Céspedes Umaña, Sandra; Soto, Ismael; Souza, Richard Demo (IEEE, 2017)
      Vehicularad hocnetworks (VANETs) have emergedas a paradigm for sharing information among vehicles andinfrastructure that has the potential to provide road safety andtravellers comfort. The bandwidth limitation is one of ...
    • Céspedes Umaña, Sandra; Shen, Xuemin (Sherman) (IEEE-Inst Electrical Electronics Engineers, 2015)
      The supporting infrastructure and communications technologies for vehicular networking contexts are heterogeneous by nature. Large coverage access networks, such as 3G/4G, co-exist with wireless local area networks and ...
    • Londoño, Diego; González, Maite; Céspedes Umaña, Sandra; Bustos Jiménez, Javier; Montenegro, Gabriel (CEUR-WS, 2017)
      Constrained devices are a common factor in the Internet of Things (IoT). These devices have limited RAM and ROM memory, reduced battery, processing capacity, and transmission power. In consequence, these devices may not ...
    • Estévez Montero, Claudio; Azurdia Meza, César; Céspedes Umaña, Sandra (CRC Press, 2015-10)
      As technology keeps evolving, information becomes more accessible due to the newly acquired attributes, mainly ubiquity. The Internet of Things (IoT) is the extraction of information from the local area network and ...
    • Yáñez, Alexis; Céspedes Umaña, Sandra; Rubio Loyola, Javier (CEUR-WS, 2017)
      In this paper we present the initial steps towards a model to relate the performance of vehicular networks, characterized by the packet loss rate and the delay, with the number of nodes or vehicles participating in the ...
