The need for data processing in sensor networks has grown enormously and research on techniques that focus on efficient processing of the data as well as consumption of power have become very important. Due to the limitation of the small size of the equipment and the battery power, the energy efficiency has to be carefully considered and the architecture should be designed to efficiently transmit queries over the network. Mostly the users request aggregate values such as average values or maximum values, making the service to provide aggregate operations very important. This work proposes to add the DURING clause into SQL to calculate values during a specific long period and suggests a way to implement the aggregation service in sensor networks by applying materialized view and incremental view maintenance techniques that is used in data warehouses. Applying incremental view maintenance techniques can reduce the memory consumption and support fast computation of aggregate values. |
