      Finding the K highest-ranked answers in a distributed network 

      Zeinalipour-Yazdi, Constantinos D.; Vagena, Zografoula; Kalogeraki, Vana; Gunopulos, Dimitrios; Tsotras, Vassilis J.; Vlachos, Michail; Koudas, Nick; Srivastava, D. (2009)
      In this paper, we present an algorithm for finding the k highest-ranked (or Top-k) answers in a distributed network. A Top-K query returns the subset of most relevant answers, in place of all answers, for two reasons: (i) ...

      On the evaluation of caching in Vehicular Information Systems 

      Loulloudes, Nicholas; Pallis, George C.; Dikaiakos, Marios D. (2010)
      VANETs have been envisioned as an infrastructure for deploying Vehicular Information Systems (VIS) that among others provide drivers with an up-to-date view on the prevailing traffic conditions. In this work we evaluate ...
