Q: What do you consider the major research themes or solutions in the existing literature?

• Traditional Routing Protocols: AODV, DSR, OLSR dominate early solutions
• ML-based Security Models: SVM, Decision Tree and shallow neural nets applied for Intrusion Detection
• Trust-Based Frameworks: Much explored, node reputation, and behavior-based trust mechanisms
• AI/DRL Approaches: DRL is showing promise regarding adaptive, real-time secure routing
• Federated Learning Models: Emerging but limited – Proposed for privacy-aware IDS
• Swarm Intelligence and Bio-inspired Models: Ant colony optimization and PSO-based routing
• Hybrid Frameworks: Merging trust models with DRL is coming up

Research review services and PhD literature review help are often used to critically evaluate these themes.

Gap Insight: Nothing but outdated ML/Trust schemes; hardly any field deployment of FL and DRL in dynamic MANETs.
