A MULTILEVEL CLOUD ARCHITECTURE FOR PROCESSING SENSOR NETWORK QUERY TO INCREASE LIFETIME OF SENSOR NETWORK

These days WSNs are being used in different areas like medical services, defense, such as military target tracking and surveillance, government and environmental services like natural disaster relief, hazardous environment exploration, and seismic sensing, and so forth.  The data and information provided by these sensors are used to screen and control their deployed environment. The amount of information in sensor system is immense, heterogeneous and multidimensional in nature. Integration of cloud computing with a sensor system takes care of the issue of vast amount of capacity and computation power necessity of this type of system. This paper proposes a cloud based multilevel architecture for processing sensor network query to expand the lifetime of the target sensor network.
