Efficient Multicast Data Replication Approach for Power Consumption in Manet

Mobile Ad hoc Network (MANET) consists of mobile nodes. Nodes are connected without any infrastructure. MANET ensures 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 multicasting, data access method and power consumption in order to provide the minimum power 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, power consumption and data availability ratio. In first phase, the multicast approach is proposed to achieve higher data availability. In second phase, the data replication procedure is proposed to ensure the higher data replication rate. In third phase, the data accessibility method ensures the more data accessibility rate. In fourth phase the power consumption procedure to ensure minimum transmission and reception power. By simulation results show that the proposed scheme achieves better performance than the existing methods like DAFN and OTOO.
