Whenever distributed transaction processing in MANETs or other unreliable networks has to guarantee atomicity and isolation, a major challenge is how long-term blocking of resources can be avoided in case the mobile device looses connection to other participants of the transaction. The authors present a new technique for treating blocked data of transaction participants that wait for a coordinator's commit decision. The technique, Bi-State-Termination (BST), gives participants that have moved during transaction execution the possibility to continue transaction processing before they know the coordinator's decision on transaction commit.
