AN ENERGY AWARE SENSOR NETWORK QUERY PROCESSING SYSTEM

Recent developments in hardware have enabled the widespread deployment of sensor networksconsisting of small sensor nodes with sensing, computation, and communication capabilities. Sensor data are subject to several sources of errors resulting from power limitations, wireless communication, latency, throughput, and various environmental effects. Such errors may seriously impact theanswer to any query posed in the network. An energy efficient approach to query processing is introducedin this paper by implementing new optimization techniques applied to in-network aggregation. Wefirst discuss earlier approaches in sensors data management and highlight their disadvantages. We thenpresent our approach and evaluate it through several simulations to prove its efficiency, competence andeffectiveness
