EENMDRA: Efficient Energy and Node Mobility based Data Replication Algorithm for MANET
P. Mukilan, Amitabh Wahi · 2012
A mobile ad-hoc network (MANET) is a self- organizing, rapidly deployable network which consists of wireless nodes without infrastructure. All nodes in a MANET are capable of moving actively and can be connected dynamically. It is used in various applications like video conferencing, rescue operations, military applications, Disaster Management etc. So the data sharing in network play a vital role. In order to ensure the effective data sharing, the data replication is needed. The main aim of the work is to develop the efficient energy and node mobility based data replication algorithm to balance the Query delay, energy consumption and data availability in MANET. 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 query delay and data availability. In proposed method we focus on balancing between the node's energy consumption, data availability and delay. By simulation results show that the proposed scheme achieves better performance than the existing methods. Keywords - MANET, Data replication, Query delay, Network partition data availability and energy consumption.
