Reducing Replica Update Cost in Replicated DRTDBS

Abstract

Replication techniques have drawn a great deal of appeal in the real-time database system (RTDBS). In this technique, the replication protocol (RPCL) has been studied as one of the primary technologies. Existing RPCL causes improper resource utilization and suffers from large communication costs. Hence, the objective is to propose a solution that effectively utilizes the system resource and decreases the large communication cost. The proposed data mining algorithm identifies the frequently accessed data items, their related data access sequence, and replicate those data items on the demanded replica sites. Additionally, mutual consistency among newly created data replica and existing data replica gets satisfied with the proposed RPCL. The experimental result shows that the proposed solutions improve the performance of the system by reducing the issue of unnecessary replica updation, unnecessary storage utilization, and unnecessary bandwidth utilization.
