  • A low power listening with wake up after transmissions MAC protocol for WSNs
    Cano Bastidas, Cristina (Universitat Pompeu Fabra, 2011-05-16)
    In the last few years Wireless Sensor Networks (WSNs) have become an interesting field of research mainly due to the challenges and constraints of their design and the broad range of potential applications they can provide. ...
  • Collaborative spatial reuse in wireless networks via selfish multi-armed bandits
    Wilhelmi Roca, Francesc; Cano Bastidas, Cristina; Neu, Gergely; Bellalta, Boris; Jonsson, Anders, 1973-; Barrachina Muñoz, Sergio (Elsevier, 2019)
    Next-generation wireless deployments are characterized by being dense and uncoordinated, which often leads to inefficient use of resources and poor performance. To solve this, we envision the utilization of completely ...
  • A flexible machine-learning-aware architecture for future WLANs
    Wilhelmi Roca, Francesc; Barrachina Muñoz, Sergio; Bellalta, Boris; Cano Bastidas, Cristina; Jonsson, Anders, 1973-; Ram, Vishnu (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Lots of hopes have been placed on machine learning (ML) as a key enabler of future wireless networks. By taking advantage of large volumes of data, ML is expected to deal with the ever-increasing complexity of networking ...
  • Hierarchical range sectoring and bidirectional link quality estimation for on-demand collections in WSNs
    Valls, Victor; Sánchez, José Luis; Cano Bastidas, Cristina; Bellalta, Boris; Oliver Riera, Miquel (Elsevier, 2013)
    The paper presents two mechanisms for designing an on-demand, reliable and efficient collection protocol for Wireless Sensor Networks. The former is the Bidirectional Link Quality Estimation, which allows nodes to easily ...
  • Implications of decentralized Q-learning resource allocation in wireless networks
    Wilhelmi Roca, Francesc; Bellalta, Boris; Cano Bastidas, Cristina; Jonsson, Anders, 1973- (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Reinforcement Learning is gaining attention by the wireless networking community due to its potential to learn good-performing configurations only from the observed results. In this work we propose a stateless variation ...
  • 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 ...
  • Potential and pitfalls of multi-armed bandits for decentralized spatial reuse in WLANs
    Wilhelmi Roca, Francesc; Barrachina Muñoz, Sergio; Bellalta, Boris; Cano Bastidas, Cristina; Jonsson, Anders, 1973-; Neu, Gergely (Elsevier, 2019)
    Spatial Reuse (SR) has recently gained attention to maximize the performance of IEEE 802.11 Wireless Local Area Networks (WLANs). Decentralized mechanisms are expected to be key in the development of SR solutions for ...
  • Spatial reuse in IEEE 802.11ax WLANs
    Wilhelmi Roca, Francesc; Barrachina Muñoz, Sergio; Cano Bastidas, Cristina; Selinis, Ioannis; Bellalta, Boris (Elsevier, 2021)
    Dealing with massively crowded scenarios is one of the most ambitious goals of next-generation wireless networks. With this goal in mind, the IEEE 802.11ax amendment includes, among other techniques, the Spatial Reuse (SR) ...
  • Taking advantage of overhearing in low power listening WSNs: a performance analysis of the LWT-MAC protocol
    Cano Bastidas, Cristina; Bellalta, Boris; Sfairopoulou, Anna; Oliver Riera, Miquel; Barceló Vicens, Jaume (Springer, 2011)
    LWT-MAC is a new Low Power Listening MAC protocol for WSNs designed to rapidly react to instantaneous increases of the network load. It takes advantage of overhearing by waking up all nodes at the end of a transmission to ...
  • Towards a collision-free WLAN: dynamic parameter adjustment in CSMA/E2CA
    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 ...
