An Air Index for Data Access over Multiple Wireless Broadcast Channels

In this paper, we propose an index allocation method for data access over multiple wireless channels. Our method first derives external index information from the scheduled data, and then allocates it over upper channels. Moreover, local exponential indexes with different parameters are built within each channel for local data search. Experiments are performed to compare the effectiveness of our approach with an existing approach. The results show that our method outperforms the existing method.
