Single Phase Reliable Timeout Based Commit Protocol

Abstract

The enormous progress in applications of distributed
database systems necessitates formulation of an efficient atomic
commitment protocol. The efficiency of these protocols is vital
when higher transaction throughput is to be supported. The
existing blocking commit protocols affect over the capacity of
system resources, which worsens in distributed database system.
This paper proposes the Non Blocking Single Phase Reliable
Timeout Based Commit Protocol (SPRTBCP), an extension to the
Modified Reliable Timeout Based Commit Protocol (MRTBCP ),
maintains the atomicity and supports off -line executions and
disconnections during commitment; it decreases the cost of
wireless communication by reducing it to a single phase
commitment operation and does not maintain log agent. Hence it
reduces message complexity and average commit time . It also
supports disconnections and handoff in mobile environment.
