Atomicity is a fundamental property ensuring that allnodes reach a consistent outcome. For this, distributed mobile transactions fun-damentally require perturbation-resilient atomic commit protocols. This is chal-lenging as mobile environments are typically characterized by frequent networkand node perturbations. The environmental constraints on mobile transactionparticipants and wireless links may increase the resource blocking time of xedts. Moreover, frequent node and link failures complicate the design ofatomic commit protocols by increasing both the transaction abort rate and re-source blocking time. Hence, the deployment of classical commit protocols is notnecessarily applicable to distributed mobile environments.
