An Advance Two Phase Commit Transaction Model For Mobile Databases

摘要

Increasing demand of mobility introduced modern trends towards databases. However, issues on transaction management in mobile database still persist. This paper analyzes the existing models of transaction in mobile databases and proposes a new model that deals transactions in two phases; one giving complete rights to mobile host for committing data and second, tasking the base station to execute transactions irrespective of other networks issues like connectivity and network interoperability. The proposed model reduces transaction commit time of the model proposed by previous scheme by introducing cache at mobile end and treating disconnected mode similar to connecting mode. It further eliminates the short comings of the existing two tiers, IOT, kangaroo, planned disconnection mode and clustering schemes.
