Efficient Data Replication and Consistency Maintenance Scheme for MANETs

E2DR: Energy Efficient Data Replication in Data Grid

Abstract— Data grids are an important branch of gird computing which provide mechanisms for the management of large volumes of distributed data. Energy efficiency has recently emerged as a hot topic in large distributed systems. The development of computing systems is traditionally focused on performance improvements driven by the demand of client's applications in scientific and business domai...

An Efficient Data Replication Strategy in Large-Scale Data Grid Environments Based on Availability and Popularity

The data grid technology, which uses the scale of the Internet to solve storage limitation for the huge amount of data, has become one of the hot research topics. Recently, data replication strategies have been widely employed in distributed environment to copy frequently accessed data in suitable sites. The primary purposes are shortening distance of file transmission and achieving files from ...

Novel cluster maintenance protocol for efficient satellite integration in MANETs

An Adaptive-Grained Consistency Maintenance Scheme for Shared Data on Emergency and Rescue Applications

Efficient information sharing is difficult to achieve in the scenario of emergency and rescue operations because there is no communication infrastructure at the disaster sites. In general, the network condition is relatively reliable in the intra-site environment but relatively unreliable in the inter-site environment. The network partitioning problem may occur between two sites. Although one c...

Efficient Data Replication Scheme based on Hadoop Distributed File System

Hadoop distributed file system (HDFS) is designed to store huge data set reliably, has been widely used for processing massive-scale data in parallel. In HDFS, the data locality problem is one of critical problem that causes the performance decrement of a file system. To solve the data locality problem, we propose an efficient data replication scheme based on access count prediction in a Hadoop...
