Abstract
Reliable data transmission has been an emerging issue in ad hoc on-demand multipath distance vector (AOMDV) routing since the nodes are prone to link failures and route breaks in highly dynamic ad hoc networks owing to the selection of multiple routes between any source and destination pair based on minimal hop count. 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.
