Composed Web service transactions executed in distributed networks often require an atomic execution. Guaranteeing atomicity in mobile networks involves a lot more challenges than in fixed-wired networks. These challenges mostly concern network failures, e.g. network partitioning and node disconnection, each of which involves the risk of infinite blocking and can lead to a high number of aborts. In this paper, we introduce an extension to existing atomic commit protocols, which decreases the time during which a resource manager that is involved in a web-service is blocked. In addition, our proposal reduces the number of sub-transaction aborts that arise due to message loss or due to conflicting concurrent transactions by distinguishing re-usable and repeatable sub-transactions from aborting sub-transactions.
