For eliminating such problems, a novel node disjoint multipath routing protocol called link reliable energy efficient AOMDV (LR-EE-AOMDV) routing protocol, the extension of AOMDV is proposed. The LR-EE-AOMDV finds multiple link reliable energy efficient paths between any source and destination pair for data transmission using three metrics such as path length, path-link quality estimator (P-LQE) and a novel path-node energy estimator (P-NEE). The performance of LR-EE-AOMDV is evaluated using NS2.34 with varying network flows and number of nodes under random waypoint mobility model in terms of quality-of-service (QoS) metrics. Simulation results reveal the effectiveness of LR-EE-AOMDV routing protocol.
