“…Salman Abdul Moiz et al [14] proposed the analytical strategy as a variation in time based commit protocols in which a transaction takes place only when the anticipated execution time is within the present time value. The choice to rollback or abort is produced when the timer expires in the timeout-based processes.…”

Simultaneous access of a shared record by multiple transactions leads to conflicts while writing. Such scenario generates the problems like lost update, dirty read, nonrepeatable read etc . In such a case, transaction need to be rolled back to get the system into a consistent state. To handle these conflicts Multiversion Concurrency control (MVCC) is used. MVCC has the ability to avoid the read-write conflicts by performing the read operations using the older version when the write request is in progress. When the multiple write operation concurrently executes then the transaction is aborted or rolled back. To address the problem of rollbacks, a methodology using the Precedence Graph generation based algorithm to reschedule the sequence of the transaction is proposed. In the proposed methodology whenever there is a system failure or network failure the transaction need not be started again, rather it is partially rolled back. The proposed methodology is executed and compared with the other MVCC approached on same set of transactions defined on shared and non shared data items. It is observed that the proposed methodology achieves better execution time as compared to the methods available in the literature..

“…Single Lock Manager Approach (SLMA) [Moiz, 2007] is proposed for cellular mobile networks, in which a single lock manager resides at a fixed server and handles all lock and unlock requests from mobile clients (or nodes). Transactions are initiated and executed at mobile clients, but required data items are read from the fixed server and final updates are done at the fixed server.…”

I would like to take the opportunity to thank the people who guided and supported me during this PhD study. Without their contributions, this research would not have been possible. First, I would like to thank my PhD advisor, Dr. Le Gruenwald. During my PhD study, Dr. Gruenwald taught me how to do research, and she was always patient and helpful whenever her guidance and assistance was needed. As an international student, I found technical writing was difficult. She contributed much of her valuable time to help me improve my writing skills. She also gave advice on how to communicate and cooperate with other researchers as a professional. Therefore, I do want to show my deep appreciation to her.

“…SESAMO is based on semantic serializability and the global serializability is automatically guaranteed if each site maintains its own serializability by applying strict 2PL. Single Lock Manager Approach (SLMA) [5] is proposed for cellular mobile networks, in which only one lock manager resides at a fixed server and handles all lock and unlock requests from the mobile clients. However, these three pessimistic techniques cannot provide timely response due to their blocking nature and frequent disconnections in Mobile P2P.…”
