Comparative study of commit protocols in mobile environment: M2PC, UCM and TCOT

In the mobile environment the major issues for commit the transactions are disconnection due to mobile handoff or shut down of devices. Disconnection is frequent problem in mobile environment. This results transaction failure. A traditional two-phase commit protocol is best for the distributed environment. In case of mobile environment where devices are connected wirelessly we should deal with the issues of mobility. The paper presents comparison study of three major commit protocols in the mobile environment. The paper surveys different approaches proposed for mobile transaction and summarize how the conventional commitment are revisited to fit the needs of mobile environment.
