A query processing method for hybrid wireless-broadcast networks

In this paper, we propose a new effective query processing method through our hybrid wireless broadcast (HWB) model, which combines push and pull based broadcast and pull-based point-to-point wireless communication. Our method provides a flexible and complementary information service in different bandwidths and service ranges. The results of simulation studies show the HWB approach shortens the average waiting time and enhances the performance of the system.
