CDRA: Consistency based Data Replication Algorithm for MANET

Mobile Ad hoc Network (MANET) consists of mobile nodes which is connected without any centralized administration. The main popularity of MANET is to ensure that lack of infrastructure, self organization and no access point. Mobile nodes are sharing their data whenever and wherever it's needed. To maintain the effective data sharing, the data replication technique is needed. The main aim of the research work is to develop the data replication algorithm based on data availability, data consistency and load balancing in order to provide the minimum energy consumption and high data availability rate in the network. Due to the presence of the network partition, mobile nodes in one partition are not able to access the data hosted by nodes in the other partition. So the performance of data access is degraded. Existing methods aims at balancing trade-off between energy consumption, data availability and delay. In proposed method we are focussing on balancing between data accessibility, energy limitation and stability of wireless links. By simulation results show that the proposed scheme achieves better performance than the existing methods.
