Mobile Ad Hoc Network (MANET) is one of the world's most important new research areas. The MANET node is a small device with computer power that protects the network from limited power, memory, transfer range and various attacks. The security of wireless ad hoc networks plays an important role and is becoming more and more important in the current generation. Cluster head selection and Routing security Mobile Ad-Hoc Networks (MANETs) are major challenges in wireless sensor networks. Previous method problems are limited security of nodes, lack of certification authority, and lack of centralized monitoring points. To overcome the problems, this work proposed the method Enhanced Spider Monkey Optimization Cluster-based Secure Routing Protocol (ESMOC-SRP) for Some nodes used to select the cluster head in the model population and the cluster head is selected from the nodes. This solves the problem of different node levels and cluster head positions. This will extend the life and stability of the Wireless Sensor Network. The Trusted Node Evaluation (TNE) method uses a secure data transfer technique through the exchange of keys between the cluster structure and the CA. The proposed method is ESMOC-SRP, which is used to improve the efficiency of node reliability assessment. Reliability measurements reflect the quality of packets, the number of packets, and the reliability of measurements maintained by reliability management nodes. Can improve the data transfer integrity by exchanging keys with a Certificate Authority (CA) between nodes. The proposed trust-based Node Evaluation model secure Routing is confirmed by ESMOC-SRP performance analysis tests based on the proposed simulation parameters and performance metrics, improving the security and energy efficiency better than previous methods.
