In wireless sensor networks (WSNs), energy preservation through clustering and routing protocols has been verified as a significant effective method to extend the network lifetime. However, hot spot problem, excessive message overhead used for cluster formation, and frequent cluster maintenance are still the main challenges in clustering and routing protocols. The objective of this paper is to overcome these problems to enhance the network lifetime by proposing a new protocol combined Harris Harks Optimization Clustering with Fuzzy Routing named as HHOCFR. In HHOCFR, an improved Harris harks optimization (HHO) algorithm is utilized to select the best cluster heads (CHs) and form optimal clusters simultaneously by a novel encoding mechanism. Moreover, good point set based population initialization and neighborhood centroid opposition based learning mechanism are used to accelerate convergence and avoid being trapped into local optima. Thus, no extra message is needed for cluster formation. In addition, a fuzzy logic system (FLS) considers residual energy, energy consumption deviation of cluster, and distance to crossover point as descriptors to make decision on relay CH determination for each CH, resulting in energy balance among CHs so as to mitigate the hot spot problem. Thereafter, the CHs monitor the energy of the clusters to determine whether the rotation of CHs or re-clustering is started to maintain the clusters, which further decreases energy consumption of the network. According to the results, the average network lifetime of HHOCFR has increased by 34.

Due to crucial exchange issues, security in mobile ad hoc networks (MANETs) is more complicated. It is vital to secure MANET exchanges to ensure the network's services development. In this research, the proposed model focuses on providing trust and certificate-based Malicious Node detection for mobile adhoc networks and improving certificate revocation based on cluster head. The cluster head is crucial in eliminating falsely accused nodes. The malicious node may be easily discovered and isolated from the network using the trusted value. If the trust value falls below the trust threshold value in a trust management, the node is identified as malicious, the certificate is canceled, and the node is isolated from the network. The TSQRS protocol's integration with the CRS scheme was the main emphasis of the suggested model. The proposed model also creates more stable clusters with the help of Trust manager. When compared to other current protocols and methodologies, the findings produced by the suggested approach for the TSQRS-CRS scheme improve performance and stability in the QoS of MANETs. Finally, certain parameters were used to run the simulation, which resulted in an improved Packet Delivery Ratio, Routing Overhead, and reduced Delay. K E Y W O R D Scertificate revocation scheme, cluster head, mobile adhoc networks, trust-based secure QoS routing scheme INTRODUCTIONMANETs are wirelessly connected networks of mobile nodes. MANET has no stable topology because the nodes are always shifting from one site to another. Ad hoc networks' Nodes can send packets, forward packets, respond to routing messages, and send suggestions, among other things.The behavior of the nodes is defined by the collection of activities that are executed. As a result, the learning plan keeps track of the neighbors' actions to assess their behavior. 1,2 To route the packets, all of the nodes must work together. Cooperating nodes must have faith in one another.According to the relative distance between the nodes and the link's maintenance time, the link's quality and dependable communication are assessed. 3 The wireless sensor network (WSN) presently is one of the chosen study field in recent years as a critical aspect of industrial application. 4 Because of sensor nodes' restricted energy and communication capabilities, designing a routing protocol for WSNs is crucial to convey sensing data to the receiver 5 properly. The Internet of Vehicles may obtain traffic information through a vast amount of data acquired by sensors. 6 There is a particular need to be focused on energy consumption and the amount of delay on resource constraints of MANETs. [7][8][9] To identify the shortest path algorithm in the programme, a new approach of the best path selection with length priority based on past information needs to be taken into consideration. Different forms of intelligent driving vehicles can use this best path planning algorithm to efficiently choose the best way in a traffic network with limited height, width, and weight, accidents, and traffic co...
