This paper introduces the Mobile Nested Transactions (MNT) model for transaction processing coordination in groups of mobile devices. The model extends traditional approaches—centralized and distributed—for distributed transaction processing over mobile devices. Under the Nested Transactions approach, sub-transactions—logical work units—processing control(More)
This paper introduces a concurrency control mechanism for the Mobile Nested Transactions model (MNT), this approach extends the 2PL mechanism for read-only operations. Under Nested Transactions (NT) 2PL, every transaction must wait for its ancestor to hold (by inheritance) the control over the requested lock. This assumption reduces the performance of(More)
