Efficient Data Replication Algorithm for. Mobile Ad-Hoc Networks

A mobile ad-hoc network (MANET) is a self-configuring network of mobile routers (and associated hosts) connected by wireless links. The routers and hosts are free to move randomly and organize themselves arbitrarily. It allows mobile nodes to communicate directly without any centralized coordinator. Significant examples include establishing survivable, efficient, dynamic communication for emergency/rescue operations, disaster relief efforts, and military networks. Such network scenarios cannot rely on centralized and organized connectivity, and can be conceived as applications of Mobile Ad Hoc Networks. In all these application data or file sharing occurs between the nodes. As in ad hoc networks, since mobile host move freely network partition occurs frequently thus data availability in Ad-hoc network is reduced.In this paper, an efficient Data Replication technique for Mobile Ad-hoc networks is proposed that improve data availability by considering all the issues related with MANET such as power consumption, resource availability, response time and consistency management.
