An ARCHITECTURE MODEL for MANAGING TRANSACTIONS in DISCONNECTED MOBILE ENVIRONMENT
Journal Title: International Journal of Computer Science and Information Technologies - Year 2011, Vol 2, Issue 1
Abstract
We present an architecture model for mobile transaction management for supporting disconnected computing. In this environment, Fixed Agents in the wired network cache the frequently accessed data from the server, which can be accessed concurrently by the mobile nodes. Data Access Manager module at the Fixed Agent controls the concurrency using invalidation technique. Using this scheme, a mobile host can assign its transaction execution to Data Access Manager at the Fixed Agent before disconnection. We have proposed two types of transactions namely trusted and non trusted transactions. Non trusted transaction can be allowed to execute without authentication. But a trusted transaction can be executed after running a trust protocol. The proposed transaction management framework has been simulated in J2ME and NS2 and performance of the scheme is analysed.
