Optimized Query Processing for Wireless Sensor Networks

[Full Text]

sensor networks; query optmization; operators; aggregation functionstuple; root node



in this paper we propose an approach for query optimization in Sensor networks that cause increasing of network life time. Proposed approach reduce network consumption energy via executing operators with optimized order and optimized method for executing aggregation functions that sensor nodes do not sent unimportant data to their parents. But other existing methods such as PA and PM are sent all data to base station and base station filters data.
