MIRES : a Mobile Information and Resource Exchange System

Abstract

The rapid development of mobile technology makes the data resources more and more dispersive nowadays. Due to their limited storage capability, the mobile devices have to connect to the Internet through different protocols and exchange data as required. However, there are still many challenges on resource sharing and exchanging mechanism among mobile devices due to their computation, storage, and bandwidth limitation. This thesis focuses on three major issues in the field of mobile data management, including (1) a mobile information and resource exchange system (MIRES) model, (2) enabling techniques including multilevel metadata index for content based rich media retrieval and using sampling to provide more accurate query estimation, and (3) discussing two possible ways to buffer multimedia resources for easy access. The issues (2) and (3) are both based on the same framework of MIRES, and are concerned with how to facilitate the mobile devices to access media resources easily and efficiently. Simulated experiment and its results are also given in this thesis, showing that MIRES can help evidently enhance the efficiency of resource sharing among mobile devices.
