      The threshold join algorithm for top-k queries in distributed sensor networks 

      Zeinalipour-Yazdi, Constantinos D.; Vagena, Zografoula; Gunopulos, Dimitrios; Kalogeraki, Vana; Tsotras, Vassilis J.; Vlachos, Michail; Koudas, Nick; Srivastava, D. (2005)
      In this paper we present the Threshold Join Algorithm (TJA), which is an efficient TOP-k query processing algorithm for distributed sensor networks. The objective of a top-k query is to find the k highest ranked answers ...
