“…Distributed environment like data grid rely on sharing data and resources between various scientists and researchers to execute common tasks (Guroob and Manjaiah, 2016). Scientific applications such as high energy physics, data mining, and satellite images processing, and climate simulation, generates large amounts of data which is stored and managed by data grids (Pérez et al, 2010) The management and access to huge volume of data located at various distributed locations across the data grid, degrades due to certain network restrictions.…”

“…The experimental results shows that the proposed algorithm has reduced the data replication and communication cost. Guroob and Manjaiah (2016) proposed a novel approach, namely, Efficient Replica Consistency Model (ERCM) for propagating updates in distributed grid environment. The approach has two major offerings: Firstly, it reduces response time for both read and write operations.…”

Data replication is widely used mechanism aiming at ensuring efficient access, improving performance and providing quality data in data grids. The properties of file and their replicas can vary with time resulting to inconsistency. In this paper, an agent-based replica consistency approach, namely, Replica Consistency and Conflict Resolution (RCCR) has been proposed to improve the efficiency of the system. RCCR is hybrid approach which is used to address the problem of inconsistency in multi master environment. Additionally, the conflict resolution approach is introduced based on vector clock and version of the replica. Finally, simulated results are presented and compared with existing consistency approaches such as Pessimistic, Optimistic and One-way Replica Consistency (ORCS). The simulated results depicts that proposed RCCR approach performs better when writeable replicas are more likely to occur.
