TCOT-A Timeout-Based Mobile Transaction Commitment Protocol
October 2002 (vol. 51 no. 10)
pp. 1212-1218

Abstract—We present a transaction commit protocol, “Transaction Commit On Timeout (TCOT),” based on a “timeout” approach for Mobile Database Systems (MDS), which can be universally used to reach a final transaction termination decision (e.g., commit, abort, etc.) in any message-oriented system. Particularly suited for a wireless environment, a timeout mechanism is the only way to minimize the impact of the slow and unreliable wireless link. We compare TCOT to a modified version of 2PC to show its superiority based on commit time.
