Abstract
Data broadcasting is a scalable mechanism to disseminate information to a large number of mobile clients in a wireless environment. This paper concerns the development of a data broadcast system in a wireless environment. The broadcast data is retrieved from a central database server. We apply three different data broadcast schemes in the following order: first, we implement a filtering technique for a mobile device to select and display the desired data from incoming broadcast data items; second, the index broadcasting scheme is designed to predict the arrival of the desired data to appropriately execute the power conserving mode; third, we incorporate multiple channel environments to allow a mobile device to tune into multiple broadcast channels in order to receive the desired data. The proposed model uses a shared indices price context to demonstrate the effective use of these data broadcast schemes in order to provide efficient data retrieval. In order to develop this model, a wireless ad-hoc network infrastructure is used.
