**Algorithm 2** Analyze and optimize routing protocols  
DNN Results  
We trained a deep neural network (DNN) model on a dataset of network simulations, consisting of various features and parameters related to routing protocols for wireless networks. The dataset contained 10,000 data points, with 70% of the data used for training, 15% for validation, and 15% for testing. We used a DNN architecture with three hidden layers, each with 256 neurons, and a final output layer with three nodes representing the three routing protocols under consideration. The model was trained using the Adam optimization algorithm with a learning rate of 0.001 for a total of 100 epochs. As shown in Figure 8, after training, the DNN model achieved an accuracy of 87% on the test set, indicating that it can predict the optimal routing protocol with a high degree of accuracy for a given network scenario. Figure 8: Training and Validation Accuracy of DNN Model. The results of the training and validation of the DNN model demonstrate that this model can be used to accurately predict the optimal routing protocol, based on a set of input features and parameters. The high accuracy of our model suggests that there are discernible patterns and relationships between the input features and protocol performance, and that these can be learned by a deep neural network. As Figure 9 shows, the DNN model also provided insights into which features had the greatest impact on protocol performance. Specifically, we found that link quality, hop count, and routing table size were the most important features for predicting protocol performance, while metrics such as packet loss and latency had a smaller impact. These findings can be useful for network engineers and researchers in selecting the most appropriate protocol for a given network scenario and for optimizing network performance based on the most important features. This section of the study, which concerns the use of the DNN model, is limited by the specific dataset used for training, which may not fully capture the complexity and diversity of real-world network scenarios. Future studies should consider using larger and more diverse datasets and explore alternative DNN architectures and optimization algorithms. Nevertheless, our results demonstrate the potential of deep learning to analyze and optimize routing protocols for wireless networks, and provide a promising direction for future research in this area.
