An Access Time Cost Model for Spatial Range Queries on Broadcast Geographical Data over Air

Wireless data broadcasting is well known for its excellent scalability. Most geographical data, such as weather and traffic, is public information and has a large number of potential users. Broadcast is a good mechanism that can be used to transmit the data to users at this scale. In this paper, we propose a cost model for access time in processing spatial range queries on broadcast geographical data over air. We also propose heuristics in generating orderings of broadcast sequences and evaluate their performances based on the cost model
