Data Management for Mobile Ajax Web 2.0 Applications

摘要

Whenever Ajax applications on mobile devices have to retrieve large XML data fragments from a remote server, a reduction of the exchanged data volume may be crucial to manage limited bandwidth and limited energy of the mobile device. We propose to use an XML compression technique that compresses an XML document to a binary directed acyclic graph (DAG) and to use DAG-based DOM evaluation on the client side. Our experiments show that the data transfer for applications like amazon or eBay can be reduced to 70% of the original data transfer needed.
