The paper evaluates the performance of various Mobile Ad Hoc Network (MANET) routing protocols (AODV, DYMO, OLSR-V2 Niigata, OLSR-Inria, and RIPng) under IPv6 networks using simulation and analytical methods. Key performance metrics assessed include throughput, average jitter, end-to-end delay, efficiency, and energy consumption in different modes. The study employs the QualNet 5.0.1 simulator to conduct simulations with randomly distributed nodes in a defined area, focusing on energy traffic modeling and mobility impacts.
