%X Whenever distributed transaction processing in MANETs or other unreliable networks has to guaranteeatomicity and isolation, a major challenge is how long-term blocking of resources can be avoided in casethe mobile device looses connection to other participants of the transaction. We present a new techniquefor treating blocked data of transaction participants that wait for a coordinator¡¯s commit decision. Ourtechnique, Bi-State-Termination (BST), gives participants that have moved during transaction execution thepossibility to continue transaction processing before they know the coordinator¡¯s decision on transactioncommit. The key idea of our technique is to consider both possible outcomes (commit and abort) of unknowntransaction decisions. Within this paper, we describe a fast implementation of the fundamental relationaldatabase operations for a DBMS supporting the BST transaction synchronization protocol that avoids longtermtransaction blocking.
