چکیده

In this paper, we present a distributed algorithm for dynamic data replication of an object in a distributed system. The algorithm changes the replication scheme, i.e., number of replicas and their location in the distributed system, to optimize the amount of communication. In other words, the algorithm dynamically adapts the replication scheme of an object to the pattern of read-write requests in the distributed system. We prove that the cost of the algorithm is within a constant factor of the lower bound.

Dynamic Replication based on Firefly Algorithm in Data Grid

In data grid, using reservation is accepted to provide scheduling and service quality. Users need to have an access to the stored data in geographical environment, which can be solved by using replication, and an action taken to reach certainty. As a result, users are directed toward the nearest version to access information. The most important point is to know in which sites and distributed sy...

Improving Data Grids Performance by Using Modified Dynamic Hierarchical Replication Strategy

Abstract: A Data Grid connects a collection of geographically distributed computational and storage resources that enables users to share data and other resources. Data replication, a technique much discussed by Data Grid researchers in recent years creates multiple copies of file and places them in various locations to shorten file access times. In this paper, a dynamic data replication strate...

Multi-layer Clustering Topology Design in Densely Deployed Wireless Sensor Network using Evolutionary Algorithms

Due to the resource constraint and dynamic parameters, reducing energy consumption became the most important issues of wireless sensor networks topology design. All proposed hierarchy methods cluster a WSN in different cluster layers in one step of evolutionary algorithm usage with complicated parameters which may lead to reducing efficiency and performance. In fact, in WSNs topology, increasin...
