Mobile continuous nearest neighbor queries on air
Kwangjin Park, Patrick Valduriez, Hyunseung Choo · 2008
In this paper, we propose new spatial query processing algorithms to support Mobile Continuous Nearest Neighbor Query (MCNNQ) in wireless broadcast environments. Each client (object) computes individually the function that best captures the locations of the moving objects, while a server is only responsible for delivering information gathered from the clients. Extensive experiments demonstrate that our location-based data dissemination algorithm significantly out-performs index-based solutions.
