      Locating objects in mobile computing 

      Pitoura, Evaggelia 1967-; Samaras, George S. (2001)
      In current distributed systems, the notion of mobility is emerging in many forms and applications. Mobility arises naturally in wireless computing since the location of users changes as they move. Besides mobility in ...

      The price of selfish routing 

      Mavronicolas, Marios; Spirakis, Paul G. (2001)
      The problem of routing in congested communication networks was studied. A noncooperative network consisting of a set of m parallel links within a game theoretic framework was considered for analysis. A collection of n ...

      Weighted boolean formula games 

      Mavronicolas, Marios; Monien, Burkhard; Wagner, K. W. (2007)
      We introduce a new class of succinct games, called weighted boolean formula games. Here, each player has a set of boolean formulas he wants to get satisfied. The boolean formulas of all players involve a ground set of ...
