Abstract

Now day’s transaction failure is a common issue in mobile environment. There are various cause of transaction failure in mobile environment, some of them most common are failure of coordinator (normally which is base station in case of mobile environment), disconnection of mobile device, low battery, handoff. This paper proposes the new transaction commit protocol, Fault Tolerant Transaction Commit Protocol with Timeout Constraint (FTCOT).It support coordinator failure, handoff (in case of mobility) which reduce transaction failure. This paper extends the feature of TCOT.
