摘要
En 中文
Researchers have studied the various index structures and query processing algorithms to support efficient spatial queries in wireless communication environments. However, most previous studies have focused on server-side methods. In a server-side method, the server executes queries from individual clients and then relays the results. In our proposed method, the server transmits an index called DGI (Distributed Grid Index), and the client examines the received index to process spatial queries. The proposed index structure and search algorithm support efficient spatial queries in a wireless broadcast environment, shortening query search times. (C) 2013 Elsevier Ltd. All rights reserved.
