Mobile Ad Hoc Networks (MANETs) represent a decentralized networking paradigm in which mobile nodes dynamically establish communication without fixed infrastructure. Among the routing protocols designed for MANETs, the Ad hoc On-Demand Distance Vector (AODV) protocol remains one of the most extensively studied due to its reactive routing mechanism and adaptability to dynamic topologies. However, increasing node mobility, security threats, energy constraints, and Quality of Service (QoS) requirements have motivated the development of multiple AODV variants. This study presents a performance analysis framework for dynamic AODV protocols in MANETs through a comprehensive review and synthesis of existing enhancements. The framework evaluates routing efficiency using packet delivery ratio, end-to-end delay, routing overhead, energy consumption, route stability, and security resilience. Comparative examination of path accumulation, geocast integration, trust-based routing, intrusion detection, energy-aware optimization, and mesh-network adaptations demonstrates that no single AODV variant satisfies all performance objectives simultaneously. The findings indicate that adaptive routing approaches combining security awareness, energy efficiency, and topology responsiveness provide superior network performance under highly dynamic conditions. The proposed analytical framework offers guidance for future protocol design and optimization in MANET environments.
