Mobile ad hoc networks (MANETs) are self-organizing nodes in a mobile network that collaborate to form dynamic network architecture to establish connections. In MANET, data must traverse several intermediary nodes before reaching its destination. There must be security in place to prevent hostile nodes from accessing this data. Multiple methods were suggested in literature for securing routing; these techniques tackle different aspects of security. In order to enhance fault tolerance, wireless network multipath routing is typically used instead of the original single path routing. The routing protocol Genetic Algorithm with Hill climbing (GAHC) described in this article shows a hybrid GA-Hill Climbing algorithm that picks the optimal route in multipath. Prior to this in the beginning, the Improved fuzzy C-means algorithm method was built on density peak, and cluster heads (CHs) were chosen in a predicted manner, based on recent, indirect, and direct trust. The computation is based worth nodes are at the trust threshold found in addition. Even CHs take part in the alternate paths, the blend of all the many paths from these Cluster Heads that chooses the optimal route, which is based on the predicted hybrid protocol, as well as the optimum route’s aggregate features such as throughput, latency, and connection. This suggested technique requires a minimum amount of energy of 0.10 m joules and a small amount of delay time of 0.004 msec, which also yields a maximum throughput of 0.85 bits per second, a maximum detection rate of 91 percent and maximum packet delivery ratio of 89percent. The suggested approach was put through the paces with the selective packet dropping attack.

Mobile ad hoc networks (MANET) are self-organizing, rapidly deployable wireless networks excellent for outdoor events, communications in places lacking radio infrastructure, disasters, and military activities. Because network topologies are flexible and dynamic, security may be the most vulnerable point in the network, open to attacks including eavesdropping, routing, and application changes. MANET has more security flaws than quality of service (QoS). It is thus recommended to use intrusion detection, which regulates system to detect further security problems. Monitoring for intrusions is crucial for prevention and additional security against unwanted access. The loss of a mobile node’s power source may affect the node’s ability to forward packets, which is reliant on the system’s overall life. In this paper, the Bacteria for Aging Optimization Algorithm (BFOA), which finds the ideal hops in advancing the routing, is utilized to offer a trust-based protected and energy-efficient navigation in MANETs using a trust-based protected and energy-efficient navigation algorithm. The fuzzy clustering algorithm is activated first, and the Cluster Heads (CHs) are selected depending on the value of indirect, direct, and recent trust that each CH has. In addition, value nodes were discovered based on trust levels. Moreover, the CHs are engaged in multi hop routing, and the selection of the ideal route is based on the projected protocol, which selects the best routes based on latency, throughput, and connection within the course’s boundaries. Even without an attack, compared to the exiting methods EA-DRP & EE-OHRA the proposed secure optimization routing (BFOA) algorithm produced a minimum energy of 0.10 m joules, a minimal latency of 0.0035 m sec, a maximum throughput of 0.70 bps, and an 83 percent detection rate, with enhanced results obtained by using a selective packet dropping attack

Underwater wireless sensor networks (UWSNs) have emerged as a potent solution for oceanographic data collection, underwater exploration, and monitoring of underwater ecosystems. However, the unique and harsh underwater environment, such as limited bandwidth, high propagation delay, and significant energy constraints, creates myriad challenges in designing energy-efficient communication protocols. This research explores developing and implementing innovative energy-efficient protocols tailored for UWSNs to enhance their longevity and reliability. The authors introduce a novel protocol that employs a hybrid of clustering and routing algorithms to minimize energy consumption and enhance network longevity. The protocol is designed to tackle energy consumption, data transmission reliability, and network scalability issues. The findings from the implementation in a simulated underwater environment demonstrate notable improvements in energy conservation and network lifespan, thereby affirming the potential applicability of the proposed protocols in real-world underwater applications.

A wide range of applications include in Wireless Sensor Networks (WSNs), and it is being used extensively in data collection specifically to process the mission-critical tasks. The implementation of routing protocols of energy-efficient (EE) is one of the significant challenging jobs of Sensor Networks (MC-SSN) and Mission Critical Sensors. In hierarchical routing protocols, higher EE can reach when compared to the flat routing protocols. The network’s scheduling process doesn’t support enhanced balanced Energy-efficient network-integrated super-heterogeneous (E-BEENISH), which discusses earlier. An Energy. Energy efficient Time scheduling based particle swarm optimization unequal fault tolerance clustering protocol (EE-TDMA-PSO-UFC) is proposed in this paper. Based on the distance parameter, an efficient cluster head (CH) is selected in this protocol. Owing to the unexpected failure of MCH (Master Cluster Head), an additional “CH” is chosen that is termed as Surrogate cluster head (SCH) for the restoration of network’s connectivity in the protocol of PSO-UFC. Based on TDMA (Time Division Multiple Access) protocols, the consumption of Energy. Energy is reduced with the allocation of timeslots during transmission of data. Using the technique of EE-TDMA-PSOUFC, the network’s lifespan improves than CEEC and E-BEENISH protocols according to the assessment of simulation results.

VANET has received increased attention in recent years due to its wide variety of applications for traffic management. However, identifying the best route remains a challenge in VANET due to its dynamic topology. Moreover, existing routing protocols are inefficient in providing security, leading to various routing attacks. Among these attacks, the wormhole attack is particularly severe. Currently, there are existing solutions that detect wormholes either through Vehicle-to-Vehicle (V2V) or Road Side Unit (RSU)-based methods. In this paper, we propose a wormhole detection technique that utilizes mobility, the number of neighboring vehicles, and path analysis at both $V2V$ and RSUs. In our result analysis, we compare the V2V-based solution with the RSU-based solution. Our results show that for fast detection of wormhole attacks, we require a wormhole detection mechanism at $V2V$ . Conversely, to reduce false positives and negatives, we need a wormhole detection mechanism at RSUs.
