Global Index for Multi Channel Data Dissemination in Mobile Databases

Data broadcasting strategy is known as a scalable way to disseminate information to mobile users. However, with a very large number of broadcast items, the access time of mobile clients increase accordingly, due to high waiting time for mobile clients to find their data of interest. One possible solution is to split the database information into several broadcast channels. In this paper, we introduce global indexing technique for multi broadcast channels. A simulation model is developed to find out the performance of the technique.
