Dual Phased Commit Transaction Model for Mobile Databases

Ayesha Nayyar, Ubaid-UR-Rehman

Abstract—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 management in mobile databases and proposes a new model that deals transactions in two phases; one giving complete rights to mobile host for updating data and second, makes use of the computational capabilities of fourth generation mobile devices for databases manipulation irrespective of other networks issues like connectivity and network interoperability. The proposed model reduces transaction commit time 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.

Index Terms—distributed databases; mobile database systems (MDS); global system for Mob
