Multi-Agent System Using G-XMDR for Data Synchronization in Pervasive Computing Environments

This paper extends XMDR[19] into G-XMDR (Global-Extended Metadata Registry) to ensure the interoperability of data, and to describe multi agent system using G-XMDR. The proposal G-XMDR will be solved the problem of data heterogeneity and inconsistency in sharing and exchanging each local data in virtual pervasive computing environments. Data heterogeneity is generated by different definition or mismatched expression of the same meaning data. Therefore, we define and design G-XMDR based on XMDR(ISO/IEC 11179) specification to interoperate various each local data in pervasive computing. We also describe our synchronizing multi agent system, which uses G-XMDR to solve data heterogeneity for data interoperability through synchronizing data. It provides more efficient agent through reducing errors that happened on synchronizing requests and adding new pervasive computing environments with their own each local data.
