This document presents a machine learning approach for routing in mobile ad hoc networks (MANETs) to improve security and performance. The proposed approach uses reinforcement learning to establish the shortest and most stable path for routing packets from the source to destination. Simulation results show that the reinforcement learning approach reduces transmission delay, increases packet delivery ratio by up to 35%, and decreases energy consumption compared to traditional routing methods for MANETs. The document also discusses using machine learning for intrusion detection and trust evaluation in MANETs to enhance security against various attacks.
