However, this approach fails to focus on the selfish nodes. To address this, a trust-aware routing protocol using the Hierarchical Manta Ray Foraging Optimization Algorithm (HMRFOA) with selfish node detection in MANET (SND-MSWGCN-TRP-MANET) is proposed in this manuscript. Initially, clustering is processed using Localized Sparse Incomplete Multiview Clustering (LSIMVC). The node is clustered by merging or combining two maximum comparable cluster nodes; then, the clustered node is assigned to the Mud Ring Optimization Algorithm (MROA), where the cluster head is selected using the parameters, such as energy (E), distance (Dist), delay (D), and quality of service (QoS). The selected cluster head is fed to the Multiscale Superpixel-Guided Weighted Graph Convolutional Network (MSWGCN) for effectively detecting the selfish node to ensure secure and efficient data routing in MANET. Finally, trust-aware routing is performed using the HMRFOA, where it selects the optimal path. Then, the proposed SND-MSWGCN-TRP-MANET is implemented, and the performance metrics like energy consumption, time consumption, end-to-end delay, throughput, average delay, packet delivery ratio (PDR), and packet loss ratio (PLR) are examined.

This publication proposes an efficient deep-learning strategy for Joint Power Resource Allocation and Radar Target Assignment (JPRA-RTA) in distributed radar networks with ground-based transmitters and aerial receivers. The method has two phases: (i) Point-wise Activations Steerable Convolutional Neural Networks (Point-ConNet) with Narwhal Optimizer for joint power allocation and radar target assignment, and (ii) Hybrid Snow Geese Alpine Skiing Optimization (Hyb-SGASO), for resource allocation. First, the JPRA-RTA problem is converted into a regression problem solvable by Point-ConNet with the Narwhal Optimizer, enhancing computational efficiency, accuracy, fast convergence, and scalability. After optimizing power and radar target assignment, Hyb-SGASO is used to optimize remaining resources like communication bandwidth, ensuring balanced and efficient resource use. Thus, the proposed Point-ConNet- Hyb-SGASO method is implemented in Python and the method's performance is evaluated using metrics such as power consumption, spectral capacity, spectral efficiency, energy efficiency, tracking frame accuracy, cumulative distribution function (CDF), Mean Square Error (MSE), and Root Mean Square Error (RMSE), demonstrating significant improvements over traditional approaches.

Wireless sensor networks (WSNs), consisting of low-cost, compact sensors, are crucial for IoT systems, enabling data collection for tasks like surveillance and tracking. A major challenge in WSNs is achieving energy efficiency while extending network lifetime (NLT), necessitating effective clustering and routing strategies. Numerous existing methodologies for energy-efficient clustering and routing exhibit potential; however, they are hindered by constraints including inadequate adaptability to fluctuating network conditions, suboptimal selection of s cluster heads (CHs), and uneven energy consumption, resulting in diminished network longevity and efficacy. These issues require novel strategies to improve overall performance. To tackle this issues, this research presents a novel hybrid technique combining fuzzy logic with barnacles mating optimization (FL-BMO) to identify the most optimal CHs by evaluating critical criteria like average sink distance, average intracluster distance, residual energy, and CH balance factor. The FL-BMO methodology utilizes fuzzy logic to address uncertainties in sensor data, and the BMO algorithm, modeled after barnacle mating patterns, offers a resilient and adaptable optimization process, markedly enhancing energy efficiency and network longevity. In addition, an innovative natural-inspired hybrid cross-layer sunflower optimization routing (NiHCLR-SFO) technique has been introduced that entails optimal routing path selection. This approach balances exploration and exploitation during a route selection process, integrating multiple layers of the network functionality which eventually results in improved routing efficiency and network throughput. Such a hybrid approach has been implemented in MATLAB. The proposed method is compared with fuzzy reinforcement learning based data gathering (FRLDG), neuro-fuzzy-emperor penguin optimization (NF-EPO), bio-inspired cross-layer routing (BiHCLR), and fuzzy rule-based energy-efficient clustering and immune-inspired routing (FEEC-IIR) protocols.
