The query processing of SPATIAL is evolved into essential portion of several modern cell applications. Currently, there is a developing interest under the application of location-based spatial queries (LBSQs) that show the combination of spatial queries which get the data depending on present places of cell phone users. User flexibility and information exchange by wireless connection provide LBSQs with unique features with which the common spatial query processing does not mention under important databases.

The novel query processing methods should be conceived to control the modern disputes. They are mobile query semantics, great workload, query promptness and accuracy, number of modules, wireless information broadcast, and sharing-based nearest neighbor queries.

Basically, there are two concepts for cell information entry. They are on-demand access design and wireless broadcast design. The point-to-point communications are organized among the server and the cell clients for on-demand access model and the server executes the queries submitted by the clients on request. The server broadcasts the data under wireless channels for wireless broadcast design and the users are in charge to filter the data.

 An instance of this method is the Microsoft Direct Band Network. The benefit to broadcast the design by on-demand design is the scalable concept. Nevertheless, the broadcast design includes great latency like the clients need to wait for the data which they require under broadcasting form.


The methods do not make use of productivity under wireless broadcast system in which sequential information entry is assisted. It might not include great client populations. The client makes use of network of fee-based cellular-type to obtain the particular functional limit. Users should show their present place and send to the server.
