Abstract: Mobile commerce is the next growing area in electronic commerce and mobile computing. These are sophisticated, data intensive mobile applications whose success strongly depends on the efficiency by which data are disseminated to a large number of mobile users. Different techniques have been put forward of which the most promising are the push-based techniques that explore the asymmetry in wireless communication and the reduced energy consumption of the receiving mode on mobile devices. This paper proposes a new broadcast indexing scheme, termed "Constant-Size I-node Distributed Indexing" (CI), that offers more energy savings in practical applications. Our detailed simulation results indicate that CI which is a variant of the currently best performing Distributed Indexing, outperforms the latter for broadcast sizes of 12,000 or fewer data items, reducing the access time up to 25% and tuning time up to 15%.
