<p><b>Abstract</b>—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.</p>
