ENHANCING DATA AVAILABILITY THROUGH REPLICATION IN MOBILE ADHOC NETWORKS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 8
Abstract
A Mobile Ad-hoc Network (MANET) is a self-configured infrastructure-less network. It consists of autonomous mobile nodes that communicate over bandwidth-constrained wireless links. Nodes in a MANET are free to move randomly and organize themselves arbitrarily. They can join the network or quit the network in an unpredictable way, such rapid and untimely disconnections may cause network partitioning. In such a case, the network faces multiple difficulties, which in turn can dramatically impact the applications deployed on top of it. One major problem is data availability. Replicating data on multiple nodes can improve availability and response time. Determining “when” and “where” to replicate data in order to meet performance goals with many users and files, and dynamic network characteristics are difficult. We identify the issue of power consumption and propose an efficient method to replicate data in appropriate nodes in the network.
