Transaction processing monitors featuring nested transactions are in the core model for mission-critical applications. In this paper, an atomic commit protocol for nested transactions over mobile devices combined with a concurrency control mechanism is introduced. The monitor features a flexible and goal persistent technique dealing with the loss of communication-a latent risk in mobile environments-, whilst safekeeping the transaction ACID properties. The implementation runs over the JADE framework. The initial results of performance for complex enough tests on a mobile devices network are presented.
