    Federated Averaging (FedAvg) is the most common aggregation method used in Federated learning, which performs a weighted averaging of the updates based on the sizes of the individual datasets of each client. A raising ...
  • Node injection link stealing attack 

    Zari, Oualid; Parra Arnau, Javier; Ünsal, Ayse; Önen, Melek (Springer, 2024)
    Conference lecture

    We present a stealthy privacy attack that exposes links in Graph Neural Networks (GNNs). Focusing on dynamic GNNs, we propose to inject new nodes and attach them to a particular target node to infer its private edge ...
  • Diseño de diferentes clases de usuarios en un servicio video-streaming adaptativo 

    Martín Faus, Isabel Victoria; Aguilar Igartua, Mónica; Mata Diaz, Jorge (2007)
    Conference report
    Open Access
    The provision of end-to-end Quality of Service (QoS) for multimedia services over IP-based networks is already an open issue. To achieve this goal, service providers need to manage Service Level Agreements (SLAs), which ...
  • On the necessity of counterfeits and deletions for continuous data publishing 

    Tobar Nicolau, Adrián; Parra Arnau, Javier; Forné Muñoz, Jorge (Springer, 2024)
    Conference lecture
    Restricted access - publisher's policy
    Continuous data publishing is the scenario where a dataset is published at different times, while it changes between publications through insertion of new tuples, reinsertions, deletions and updates of previously published ...
  • Analytical definition of SLA parameters in a video-on-demand service 

    Martín Faus, Isabel Victoria; Alins Delgado, Juan José; Aguilar Igartua, Mónica; Mata Diaz, Jorge (IEEE / Hung-Keng Pung, Francis Bu-Sung Lee, Chen-Kong Tham, Saira Kuttan, 2004)
    Conference report
    Open Access
    In this work we propose to use a set of equations to calculate some user's level parameters expressed in the Service Level Agreements (SLA). As example, we particularize these expressions for a Video-on-Demand service (VoD) ...
  • Modelling an adaptive-rate video-streaming service using Markov-rewards models 

    Martín Faus, Isabel Victoria; Alins Delgado, Juan José; Aguilar Igartua, Mónica; Mata Diaz, Jorge (Institute of Electrical and Electronics Engineers (IEEE), 2004)
    Conference report
    Open Access
    Nowadays dynamic service management frameworks are proposed to ensure end-to-end QoS. To achieve this goal, it is necessary to manage Service Level Agreements (SLA) which specify quality parameters of the services operation ...
  • Design of an adaptive-rate video-streaming service with different classes of users 

    Martín Faus, Isabel Victoria; Aguilar Igartua, Mónica; Mata Diaz, Jorge (Springer, 2006)
    Conference report
    Open Access
    The provision of end-to-end Quality of Service (QoS) for multimedia services over IP-based networks is already an open issue. To achieve this goal, service providers need to manage Service Level Agreements (SLAs), which ...
  • Diseño de esquema de carga/descarga para vehículos eléctricos en entornos urbanos 

    Bazán Guillén, Alberto; Barbecho Bautista, Pablo; Aguilar Igartua, Mónica (2023)
    Conference report
    Open Access
    Con la creciente popularidad de los vehículos eléctricos la necesidad de estrategias de carga eficientes y efectivas se ha vuelto primordial. La programación de la carga de los vehículos eléctricos puede reducir los costos ...
  • Composition in differential privacy for general granularity notions 

    Guerra Balboa, Patricia; Miranda Pascual, Àlex; Parra Arnau, Javier; Strufe, Thorsten (Institute of Electrical and Electronics Engineers (IEEE), 2024)
    Conference lecture
    Open Access
    The composition theorems of differential privacy (DP) allow data curators to combine different algorithms to obtain a new algorithm that continues to satisfy DP. However, new granularity notions (i.e., neighborhood ...
  • SLOW-based pseudonym changing schemes for location privacy in vehicular networks 

    Lomas, Mateo Sebastian; Paspuel, Robinson; Iza Paredes, Cristhian; Aguilar Igartua, Mónica (Association for Computing Machinery (ACM), 2023)
    Conference report
    Restricted access - publisher's policy
    Location privacy is a critical aspect of vehicular networks. Privacy schemes adopt diverse methods to minimize vehicle traceability. These schemes include pseudonym periodical changes, silent periods, context-based approaches, ...
  • GNB-RPL: Gaussian Naïve Bayes for RPL routing protocol in smart grid communications 

    Mezher, Ahmad Mohamad; Dueñas, Carlos Lester; Rebollo Monedero, David; Cárdenas-Barrera, Julián; Aguilar Igartua, Mónica; Meng, Julian; Castillo Guerra, Eduardo (Association for Computing Machinery (ACM), 2023)
    Conference report
