Today's real-time systems (RTS) are characterized by managing large volumes of dispersed
data making real-time distributed data processing a reality. Large business houses need to …

In advanced real-time distributed computing databases, the main performance criterion is to
reduce the 'deadline miss' by the transactions; of course, consistency constraints also need …

With the rapid advances in mobile computing technology, there is an increasing demand for
processing real-time transactions in a mobile environment. This paper studies concurrency …

Although there are several factors contributing to the difficulty in meeting distributed real time
transaction deadlines, data conflicts among transactions, especially in commitment phase …

With rapidly increasing interest in distributed real-time database systems (DRTDBS), data
conflicts amongst distributed transactions have become a crucial factor which negatively …

High priority two phase locking (HP2PL) concurrency control algorithm can be used for
accessing of data items to resolve conflicts amongst the concurrently executing transactions …

In broadcast environments, the limited bandwidth of the upstream communication channel
from the mobile clients to the server bars the application of conventional concurrency control …

The two-phase locking with high priority (2PL-HP) protocol is a broadly used concurrency
control protocol as it better handles the priority inversion problem. However, its performance …

Many recent studies have suggested that the optimistic concurrency control (OCC) protocols
outperform the locking-based protocols in real-time database systems (RTDBS). However …

Database performance is an important aspect of database usability. Distributed real time
database systems (DRTDBS) must be designed on all levels of database architecture to …
