Empowering Data Placement for Ad-hoc Queries in Mobile Broadcast Environments

Data broadcast with its scalability feature provides a strong backbone for the digital information delivery. Such a feature is especially significant for mobile users with inherent power limitations in asymmetric communication environments. This paper presents a specific broadcast ordering scheme supported by advanced structure and access mechanism for ad-hoc queries in mobile data broadcast environments. The proposed scheme aims to minimize both query-access and tuning times by specifying a new message and ordering structure. As a proof of concept, we carry out experimentation of the proposed scheme in comparison with the conventional models. The result of the experiments are presented and discussed in the paper.
