Abstract:
Distributed System is a collection of independent
computers that appears to its users as a single
coherent system. Distributed processing has become
more and more important and attractive with
progress in the areas of computer networks and
distributed system. A consistency model is a contract
between processes and data store. If processes agree
to obey certain rules, the data store promises to work
correctly. Normally, a process that performs a read
operation on a data item, expects the operation to
return a value that shows the results of the last write
operation on that data. In the absence of a global
clock, it is difficult to define precisely which write
operation is the last one. This leads to a range of
consistency models. This paper intends to develop
client-centric consistency model by using monotonicwrite
consistency control and vector clock time
synchronization algorithm.
