Concurrency Control Protocol for Nested Transactions in Real-Time Databases
In this paper we consider real-time concurrency control for the nested transaction model. We analyze problems that have pure optimistic and pessimistic approaches. As the solution...

Distributed Overload Control for Real-Time Replicated Database Systems
: In order to meet their temporal constraints, current applications such as Web-based services and electronic commerce use the technique of data replication. To take the replicatio...

Dynamic Adjustment of Serialization Order Using Timestamp Intervals in Real-Time Databases
Although an optimistic approach has been shown to be better than locking protocols for real-time database systems (RTDBS), it has the problems of unnecessary restarts and heavy re...

Timeliness via Speculation for Real-Time Databases
Various concurrency control algorithms di er in the time when con icts are detected, and in the way they are resolved. In that respect, the Pessimistic and Optimistic Concurrency ...

Multiversion Locking Protocol with Freezing for Secure Real-Time Database Systems
Database systems for real-time applications must satisfy timing constraints associated with transactions. Typically, a timing constraint is expressed in the form of a deadline and ...
