k Nearest Neighbor Search for Location-Dependent Sensor Data in MANETs
IEEE Access, 2015 K nearest neighbor (kNN) queries, which retrieve the k nearest sensor data items associated with a location (location-dependent sensor data) from the location of the query issuer, are useful for location-based services in mobile environments.

Reverse Query Processing [PDF]
2007 IEEE 23rd International Conference on Data Engineering, 2007 Generating databases for testing database applications (e.g., OLAP or business objects) is a daunting task in practice. There are a number of commercial tools to automatically generate test databases. These tools take a database schema (table layouts plus integrity constraints) and table sizes as input in order to generate new tuples.
