A Mobile Database Sharing Protocol to Increase Data Availability in Mobile Environments

This paper presents a mobile database sharing protocol to improve data availability in mobile environments. Long disconnection periods of mobile hosts could cause data inconsistency and blocking of mobile transactions. The proposed mobile database sharing protocol allows two conflict data caching modes to reduce the blocking of mobile transactions that access to shared data. Furthermore, data can be directly shared among mobile hosts that are being disconnected from the database servers. Data consistency is ensured via the execution constraints and dependency among transactions.
