  • Sanabria Russo, Luis; Barceló Vicens, Jaume; Bellalta, Boris; Gringoli, Francesco (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Collisions are a main cause of throughput degradation in wireless local area networks. The current contention mechanism used in the IEEE 802.11 networks is called carrier sense multiple access with collision avoidance ...
  • Liao, Ruizhi; Bellalta, Boris; Oliver Riera, Miquel; Niu, Zhisheng (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    As wireless devices boom and bandwidth-hungry applications (e.g., video and cloud uploading) get popular, today's wireless local area networks (WLANs) become not only crowded but also stressed at throughput. Multiuser ...
  • Liao, Ruizhi; Bellalta, Boris; Barceló Vicens, Jaume; Valls, Victor; Oliver Riera, Miquel (Springer, 2013)
    According to the ongoing IEEE 802.11ac amendment, the wireless network is about to embrace the gigabit-per-second raw data rate. Compared with previous IEEE standards, this significant performance improvement can be ...
  • Barceló Vicens, Jaume; Bellalta, Boris; Cano Bastidas, Cristina; Sfairopoulou, Anna; Oliver Riera, Miquel; Verma, Kshitiz (Springer Verlag, 2011)
    Carrier sense multiple access with enhanced collision avoidance (CSMA/ECA) is a distributed MAC protocol that allows collisionfree/naccess to the medium in WLANs. The only difference between CSMA/ECA and the well-known ...
  • Liao, Ruizhi; Bellalta, Boris; Cao, Trang Minh; Barceló Vicens, Jaume; Oliver Riera, Miquel (Springer, 2015)
    Due to the dominance of the downlink traffic in Wireless Local Area Networks (WLANs), a large number of previous research efforts have been put to enhance the downlink transmission, namely, from the Access Point (AP) to ...
