Adjourn State Concurrency Control Avoiding Time-Out Problems in Atomic Commit Protocols

Abstract-- The use of atomic commit protocols in mobile adhoc networks involves difficulties in setting up reasonable timeouts for aborting a pending distributed transaction. This paper presents the non-blocking Adjourn State, a concurrency control modification which makes time-outs in an atomic commit protocol for aborting a transaction unnecessary. Further, it enhances concurrency among transactions performing conflicting accesses to resources used by completed distributed transactions waiting for the commit protocol to be initiated.
