Above-Threshold Queries of Environmental Conditions Based on Bilinear Interpolation in Wireless Sensor Networks

Above-Threshold Queries of Environmental Conditions Based on Bilinear Interpolation in Wireless Sensor Networks

Wireless sensor networks can be regarded as sensor database systems, which permit users to query sensor data of interest. Among various spatial database queries, we focus the area-wise aggregate queries in the region where the sensor values are above a predefined threshold, which are summarized as a...
