Latest research in Multipath Routing in Mobile Ad Hoc Networks (MANETs) focuses on improving reliability, load balancing, and energy efficiency by establishing multiple alternative routes between source and destination nodes. Recent studies enhance traditional protocols such as AOMDV, AODVM, and SMR with QoS-aware, energy-efficient, and trust-based mechanisms to maintain stable connectivity under frequent topology changes. Optimization techniques based on swarm intelligence, hybrid evolutionary algorithms, and machine learning are increasingly applied for dynamic path selection, reducing end-to-end delay and minimizing packet loss. Cluster-based and secure multipath frameworks now integrate trust evaluation, cross-layer feedback, and adaptive route maintenance to counter malicious attacks and ensure efficient data dissemination. Comparative analyses highlight that multipath routing significantly improves throughput, fault tolerance, and network lifetime compared to single-path methods. Overall, the latest advances in multipath routing aim to create intelligent, energy-aware, and secure routing solutions that deliver high performance and resilience in rapidly changing MANET environments.
