Sensor network applications rely heavily on aggregate queries Queries are also considered a natural way for users to interact with the sensor network 23 Therefore several studies have been carried toward aggregate query processing in sensor networks 20 21 23 The common approach to query processing in sensor networks has two phases

14 15 and in-network query processing 2 5 7 16 A survey of the applications and the challenges that sensor networks introduce is presented in 4 For monitoring queries that aggregate the observed values from a group of sensor nodes 5 suggested the construction of a greedy aggrega-tion tree that seeks to maximize the number of

In addition when the sensing areas of sensor nodes are disjoint the coordinator of each sensor becomes itself and we perform traditional aggregate query processing Thus the problem we are considering is a generalization of the traditional in-network aggregation problem
