IEEE International Conference on Computational Aggregate Query Processing Sensor Networks

with and without data aggregation in wireless sensor networks and energy constrained wireless sensor network In wireless sensor network data transmission took place in multi hop fashion where each node forwards its data to the neighbor node which is nearer to sink Since closely placed nodes may sense same data above approach cannot be considered as energy efficient An improvement over We present a novel approach to processing continuous aggregate queries in sensor networks which lifts the assumption of tree based routing Given a query workload and a special purpose gateway node where results are expected the query optimizer exploits query correlations in order to generate an energy efficient distributed evaluation plan
