      Article
      Restricted access - publisher's policy
      The assignment game introduced by Shapley and Shubik (1972) [6] is a model for a two-sided market where there is an exchange of indivisible goods for money and buyers or sellers demand or supply exactly one unit of the ...

      Findings The study identifies the main components that a trust model must provide, and compares the way they are implemented. It finds that the lack of unity in the different proposed approaches makes it difficult to ...
    • A Stackelberg game for modelling asymmetric users' behavior in grid scheduling 

      Kolodziej, Joana; Xhafa Xhafa, Fatos; Bogdanski, Marcin (Institute of Electrical and Electronics Engineers (IEEE), 2010)
      Conference report
      Open Access
      In traditional distributed computing the users and owners of the computational resources usually belong to the same administrative domain. Therefore all users are equally entitled to use the resources. The situation is ...

      León Gutiérrez, Xavier; Navarro Moldes, Leandro (Elsevier, 2013-01)
      Article
      Restricted access - publisher's policy
      Energy-related costs are becoming one of the largest contributors to the overall cost of operating a data center, whereas the degree of data center utilization continues to be very low. An energy-aware dynamic provision ...

      Freixas Bosch, Josep (CRC Press, 2019-12-06)
      Part of book or chapter of book
      Open Access
      A value that has all the ingredients to be a generalization of the Shapley value is proposed for a large class of games called j-cooperative games which are closely related to multi-choice games. When it is restricted to ...
    • Accessibility measures to nodes of directed graphs using solutions for generalized cooperative games 

      Amer Ramon, Rafael; Giménez Pradales, José Miguel; Magaña Nieto, Antonio (2012-02)
      Article
      Restricted access - publisher's policy
      The aim of this paper consists of constructing accessibility measures to the nodes of directed graphs using methods of Game Theory. Since digraphs without a predefined game are considered, the main part of the paper is ...
    • Achievable hierarchies in voting games with abstention 

      Freixas Bosch, Josep; Tchantcho, Bertrand; Tedjeugang, Narcisse (Elsevier, 2014-07-01)
      Article
      Open Access
      It is well known that he influence relation orders the voters the same way as the classical Banzhaf and Shapley-Shubik indices do when they are extended to the voting games with abstention (VGA) in the class of complete ...
    • Adaptive channel assignment for wireless mesh networks using game theory 

      Amiri Nezhad, Maryam; Cerdà Alabern, Llorenç (Institute of Electrical and Electronics Engineers (IEEE), 2011)
      Conference report
      Open Access
      Channel assignment has been extensively researched for multi-radio wireless mesh networks, but it is still very challenging when it comes to its implementation. In this paper we propose a semi-dynamic and distributed channel ...

      Article
      Restricted access - publisher's policy
      The Banzhaf power index for games admits several extensions if the players have more than two ordered voting options. In this paper we prove that the most intu-itive and recognized extension ...
