Mobile Ad Hoc Networks (MANETs) are dynamic, infrastructure-less networks that rely on node cooperation for communication throughout the environment. It is a collection of autonomous, self-organizing mobile nodes that are connected without the need for a centralized infrastructure. Efficient clustering and secure routing are essential for improving the performance, stability, and security of such networks. This paper proposes a hybrid approach that combines Modified Fuzzy-Based Cluster Head (CH) Selection with Pity Beetle Optimization (PBO) for secure routing, and integrates Philippine Eagle Optimization (PEO) for global route enhancement. The fuzzy-based method ensures optimal and energy-efficient selection of CHs, while PBO strengthens route security against potential intrusions. PEO further refines the path selection, enhancing data delivery and minimizing latency. Experimental results demonstrate that PBO-PEO significantly reduces energy consumption, enhances packet delivery, and prolongs network lifetime, outperforming traditional routing protocols. The proposed framework contributes to the development of intelligent, power-aware routing protocols for MANETs, ensuring sustainable and resilient network communication. The suggested PBO-PEO have a longer network lifetime of 2400, higher throughput of 5ms, better energy consumption of 990, and less delay 12ms.
