  • Analysis of dynamic channel bonding in dense networks of WLANs
    Faridi, Azadeh; Bellalta, Boris; Checco, Alessandro (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Dynamic Channel Bonding (DCB) allows for the dynamic selection and use of multiple contiguous basic channels in Wireless Local Area Networks (WLANs). A WLAN operating under DCB can enjoy a larger bandwidth, when available, ...
  • Comprehensive evaluation of the IEEE 802.15.4 MAC layer performance with retransmissions
    Faridi, Azadeh; Palattella, Maria Rita; Lozano Solsona, Angel; Dohler, Mischa; Boggia, Gennaro; Grieco, Luigi Alfredo; Camarda, Pietro (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    Supported by IEEE 802.15.4 standardization activities, embedded networks have been gaining popularity in recent years. The focus of this paper is to quantify the behavior of key networking metrics of IEEE 802.15.4 ...
  • Distortion control for delay-sensitive sources
    Faridi, Azadeh; Ephremides, Anthony (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We investigate the problem of finding minimum-distortion policies for streaming delay-sensitive but distortion-tolerant data. We consider cross-layer approaches which exploit the coupling between presentation and transport ...
  • On the distributed construction of a collision-free schedule in multi-hop packet radio networks
    Barceló Vicens, Jaume; Bellalta, Boris; Cano Bastidas, Cristina; Faridi, Azadeh; Oliver Riera, Miquel (Springer, 2014)
    This paper introduces a protocol that distributively constructs a collision-free schedule for multi-hop packet radio networks in the presence of hidden terminals. As a preliminary step, each wireless station computes the ...
  • Performance analysis of a multiuser multi-packet transmission system for WLANs in non-saturation conditions
    Bellalta, Boris; Faridi, Azadeh; Barceló Vicens, Jaume; Daza, Vanesa; Oliver Riera, Miquel (Elsevier, 2014)
    Multiuser Multi-Packet Transmission (MPT) from an Access Point (AP) equipped with multiple antennas to multiple single-antenna nodes can be achieved by exploiting the spatial dimension of the channel. In this paper we ...
