A Node-disjoint Multipath Routing Protocol Based on AODV

Mobile ad hoc networks are typically characterized by high mobility and frequent link failures, so routing protocol is crucially important. Multipath routing can be utilized so that alternate paths are available to reduce link failure. A node-disjoint multipath routing protocol based on AODV was proposed in the paper. The main goal is to discover multiple node-disjoint paths with a low routing overhead during a route discovery. We also pay attention to residuary energy of nodes. Simulation results show that the proposed protocol results in significant performance improvement.
