    • A two-way radio communication across a multi-hop wireless sensor network based on a commercial IEEE 802.15.4 compliant platform 

      Herrera, Laura; Calveras Augé, Anna M.; Catalán Cid, María Luisa (Elsevier, 2012)
      Conference lecture
      Open Access
      Wireless Sensor Networks, and especially IEEE 802.15.4, are originally defined for low cost applications, with low bit rates and power restrictions in mind. However, the ubiquity of the nodes and their easy connectivity ...
    • Aplicación de métodos de compresión de cabeceras TCP/IP como optimización de las comunicaciones móviles 

      Calveras Augé, Anna M.; Catalán Cid, María Luisa (Escola Tècnica Superior d'Enginyers de Telecomunicació de Barcelona, 2003)
      Article
      Open Access
      El protocolo TCP (Transmission Control Protocol) está implementado para actuar en redes fija s, donde las incidencias en la comunicación pueden interpreta rse como problemas de con ges tión. En entornos móviles, en ...
    • Design of a UMTS/GPRS Assisted Mesh Network (UAMN) 

      Paradells Aspas, Josep; Ferrer, Josep Lluís; Catalán Cid, María Luisa; Torres, Wilfredo; Catalán Cid, Miguel; Sánchez Loro, Xavier; Beltrán Martínez, María Victoria; García Villegas, Eduard; Gómez C.; Plans, Pau; Rubio, Javier; Almodóvar, Daniel; Rodellar, Daniel; Subotic, N.; Wenger, D.; Steiner, I. (Wireless World Research Forum, 2006-11-15)
      Conference report
      Open Access
      Wireless Mesh or multi-hop networks (WMNs) are well known thanks to its simplicity on deployment and the lack of infrastructure. These two advantages come with some drawbacks. WMNs have limitations with the support of ...
    • Energy efficient wireless networking of sensor nodes 

      Seyfettin Demirkol, Ilker; Paradells Aspas, Josep; Oller Bosch, Joaquim; Casademont Serra, Jordi; Calveras Augé, Anna M.; Catalán Cid, María Luisa (2013)
      Conference report
      Open Access
      Wireless sensor networks have paved the way to a new era in user applications, where information can be sensed, processed, and distributed from remote environments with minimal or no human interaction. As the sensor nodes ...
    • Implementation and evaluation of the enhanced header compression (IPHC) for 6LoWPAN 

      Ludovici, Alessandro; Calveras Augé, Anna M.; Catalán Cid, María Luisa; Gómez Montenegro, Carlos; Paradells Aspas, Josep (2009)
      Article
      Restricted access - publisher's policy
      6LoWPAN defines how to carry IPv6 packets over IEEE 802.15.4 low power wireless or sensor networks. Limited bandwidth, memory and energy resources require a careful application of IPv6 in a LoWPAN. The IEEE 802.15.4 ...
    • Infrastructureless smart cities. Use cases and performance 

      Paradells Aspas, Josep; Gómez Montenegro, Carlos; Seyfettin Demirkol, Ilker; Oller Bosch, Joaquim; Catalán Cid, María Luisa (Institute of Electrical and Electronics Engineers (IEEE), 2014)
