This paper proposes a new global index structure and processing for location-dependent queries in mobile broadcast environments. The proposed scheme consists of two essential elements for addressing spatial queries in broadcast databases. These two elements are: (i) determine the client's location in relevant to the spatial model adopted by the broadcast scheme, and (ii) obtain the required object, which corresponds to the location of the client as determined by the model. The global index's concept will enhance the efficiency of the model. We explore the effectiveness of the proposed index scheme in single and multi channel environments. Performance comparisons with the earlier work through simulated-experiments have also been carried out and the results found have been promising.
