In computing systems, one of the centric topics entails cloud computing. This dominance is attributed to the crucial role that the concept plays in the daily lives of individuals, especially in the wake of the increasing adoption of technology by individuals and organizations. Indeed, the motivation behind the establishment, adoption, and implementation of cloud computing has been attributed to the need to offer low-cost and quick consumer service provision, as well as data manipulation and storage. However, the cloud environment continues to face security threats, a trend that informs the need for further investigations and analyses that could provide room for new system improvements. The current simulation study presents a dynamic model for security management in a cloud computing environment, with the central parameter involving electronic trust. Imperatively the proposed study examines interactions between the data provider and the data owner, as well as the end user. Specifically, the proposed model is that which ensures that for authentication purposes and access permissions, there is a continuous update of trust values. From the results, the model is flexible relative to the provision of dynamic access control, a positive trend that points to its promising level of efficiency.

Mobile ad hoc networks (MANETs) have rapidly expanded in recent years, mostly as a result of the mobile devices’ obvious low cost, heterogeneity, and flexibility. When communication networks are down or inaccessible, sensors can quickly create a reliable network that can be used as a rescue data system. Industrial mobile communication has developed into a significant study area for both industry and academia in recent years. The need for data interchange between various smart devices with various latency flows is enormous. Nevertheless, there has not been as much research done in this area. The suggested work suggests a fuzzy-based improved PSO optimized in MANET to alleviate the drawbacks of the conventional routing approach. The suggested study offers a numerical modelling that can be used to carry out adaptive transmission optimization with a variety of programmable module structures and guarantee cost-effective route establishment with greater throughput, goodput, and lowest delay requirements. To find the best route, the proposed approach combines energy-optimized route construction with data-driven cluster head (CH) selection based on swarm intelligence. Particle swarm optimization- (PSO-) based clustering achieves improved delay, goodput, throughput, and path difference degree as compared to other conventional approaches, according to the extensive simulation results. The energy efficiency of a network that is decentralized is more important. The MANET device’s energy efficiency helps to extend battery life and improve network performance. This research demonstrates how the fuzzy-based improved PSO optimized in MANET helps to raise the network’s energy efficiency. As a result, network energy conservation improves network performance and battery life. Additionally, this method enhances the quality of service methodology. End-to-end delay, energy consumption, packet delivery ratio, and normalized routing overhead are measured and compared between the simulation and conventional routing protocols.
