    Ad-hoc On-Demand Distance Vector (AODV) routing protocol has been and continues to be a very active and fruitful research protocol since its introduction in the wireless ad-hoc networks. AODV uses a static value for ...

  • Dual commutative hyper-K-idelas of type 1 in hyper K-algebras of order 3 

    Torkzadeh, Lida; Zahedi, Mohammad Mehdi (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2006)
    Article
    Accés obert
    In this note we classify the bounded hyper K-algebras of order 3, which have D1 = {1}, D2 = {1, 2} and D3 = {0, 1} as a dual commutative hyper K-ideal of type 1. In this regard we show that there are such non-isomorphic bounded ...

  • Fuzzy coalitional structures (alternatives) 

    Mareš, Milan; Vlach, Milan (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2006)
    Article
    Accés obert
    The uncertainty of expectations and vagueness of the interests belong to natural components of cooperative situations, in general. Therefore, some kind of formalization of uncertainty and vagueness should be included ...

  • An orthogonality-based classification of conjectures in ortholattices 

    Trillas i Gay, Enric; Pradera Gómez, Ana (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2006)
    Article
    Accés obert
    A mathematical model for conjectures (including hypotheses, consequences and speculations), was recently introduced, in the context of ortholattices, by Trillas, Cubillo and Castiñeira (Artificial Intelligence 117, 2000, ...
