  • Optimal data compression for lifetime maximization in wireless sensor networks operating in stealth mode 

    Incebacak, Davut; Zilan, Ruken; Tavli, Bulent; Barceló Ordinas, José María; García Vidal, Jorge (Elsevier, 2015-01)
    Accés obert
    Contextual privacy in Wireless Sensor Networks (WSNs) is concerned with protecting contextual information such as whether, when, and where the data is collected. In this context, hiding the existence of a WSN from adversaries ...
  • Performance analysis of a new packet trace compressor based on TCP flow clustering 

    Holanda Filho, Raimir; Verdú Mulà, Javier; García Vidal, Jorge; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2005)
    Text en actes de congrés
    Accés obert
    In this paper we study the properties of a new packet trace compression method based on clustering of TCP flows. With our proposed method, the compression ratio that we achieve is around 3%, reducing the file size, for ...
  • Progressive encoding with non-linear source codes for compression of low-entropy sources 

    Ramírez Javega, Francisco; Lamarca Orozco, M. Meritxell; García Frías, Javier (2010)
    Text en actes de congrés
    Accés obert
    We propose a novel scheme for source coding of non-uniform memoryless binary sources based on progressively encoding the input sequence with non-linear encoders. At each stage, a number of source bits is perfectly recovered, ...
  • S3Dc: a 3Dc-based volume compression algorithm 

    Yela Reneses, Héctor; Navazo Álvaro, Isabel; Vázquez Alcocer, Pere Pau (Eurographics association, 2008)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Volumes acquired for medical purposes are continuously increasing in size, faster than graphic cards memory capacity. Large volumetric datasets do not fit into GPU memory and therefore direct rendering is not possible. ...
