Wireless data broadcast is a promising technique for information dissemination that leverages the computational capabilities of the mobile devices, in order to enhance the scalability of the system. Under this environment, the data are continuously broadcast by the server, interleaved with some indexing information for query processing. Clients may then tune in the broadcast channel and process their queries locally without contacting the server. In location-based, mobile Continual Query (CQ) systems, two key measures of Quality-of-Service (QoS) are: freshness and accuracy. In continuous monitoring an air indexing framework that outperforms the existing (i.e., snapshot) techniques in terms of energy consumption, while achieving low access latency, and constitutes the first method supporting efficient processing of continuous spatial queries over moving objects.
