Abstract:

Most current research on Location-Based Services(LBSs,for short) assumes point-to-point wireless communication, where the server processes a query and returns the query result to the user via a point-to-point wireless channel. However,LBSs via point-to-point wireless channel suffer from a tremendous amount of traffic and service requests from the user and thereby result in poor performance.In this paper,we present broadcast-based spatial query processing algorithms designed to support k-NN(k-Nearest Neighbo...
