This article aims at analyzing and comparing an adaptive algorithm-based method for improving the performance of Internet of Things (IoT) systems through simulation studies. Concentrating on active and complex scenarios, the study presents new proposals for secure and smart learning of routes, activity forecasting for nodes, link stability estimation, and flexible resource management. These methods are benchmarked against conventional algorithms to evaluate the effectiveness of the proposed solution based on routing efficiency, traffic prediction, link, resource consumption, network response time, and energy requirements. The findings are encouraging, the adaptive algorithms do improve dramatically on the standard ones making the system slower and consuming much less power. From the findings of the study it can be concluded that using adaptive algorithms in IoT can have a high impact in terms of improvement in efficiency as well as sustainability. We conclude this work by providing some directions for further research and development in the IoT field.

As the Internet of Vehicles (IoV) continues to evolve, the imperative for advanced algorithms capable of managing increased network demands, ensuring data security, and boosting overall system efficiency becomes crucial. This article introduces a novel suite of algorithms designed to enhance IoV system performance across multiple metrics. Our comprehensive simulations contrast the proposed system with three contemporary approaches the two-layer computing resource management (TCRM) model, the federated edge learning (FEL) approach, and the blockchain-based trust-value management (BTVM) approach. We demonstrate significant improvements: a latency reduction to as low as 90 ms, compared to 118 ms in TCRM, 125 ms in FEL, and 120 ms in BTVM; reliability in packet delivery with an enhancement from an initial 98% to 99.9%, compared to 98.5% in TCRM, 97.8% in FEL, and 99.5% in BTVM; resource utilization efficiency that surpasses baseline models by maintaining rates up to 85%, compared to their 60-65% in TCRM and FEL, and 75% in BTVM; and swift network response times peaking at just 50 ms, against 60 ms in TCRM, 65 ms in FEL, and 50 ms in BTVM. Additionally, our algorithms maintain robust data security levels, consistently achieving 100% effectiveness, compared to 99.2% in TCRM, 98.9% in FEL, and 99.5% in BTVM. These results underscore the proposed system's potential to significantly outperform existing solutions, paving the way for more resilient and efficient IoV architectures. The integration of these algorithms into real-world IoV applications can substantially contribute to the advancement of intelligent transportation systems.

In order to improve cybersecurity in newly developed network infrastructures, this research investigates the integration of blockchain technology with zero-trust security concepts. The zero-trust paradigm ensures continuous authentication across entities, in contrast to standard security models that often presuppose trust based on a network environment. Blockchain is used to decentralize and impose authentication intensity of communication clarity and honesty. The study compares the performance of the zero trust model enhanced by blockchain to traditional security systems in a number of parameters, such as intrusion detection rates and security breach reaction times, using extensive simulations. The findings demonstrate that the blockchain-enhanced zero-trust architecture performs better than conventional systems in both identifying and countering threats and methodically handling a large volume of transactions when under pressure. These conclusions, which emphasize significant advancements in security applications and system resilience, are predicated on the use of blockchain in zero-trust systems. Subsequent investigations will endeavor to enhance these technologies and investigate their utilization in networks across diverse intricate scenarios.

A secure delegation has a key role in collaborative and dynamic systems, and it brings new challenges to security mechanisms. Secure delegation requires a flexible model that eliminates the challenges of access control and usage control services and provides separation of duty for static and dynamic circumstances. In this study, we propose a security service model that provides delegation of rights by restricting the delegation of sensitive permission as well as restriction from unauthorized access to resources. It also ensures that the delegation process hides information and privacy from competitors in an effective manner. The proposed model removes the administrative burden and establishes an automated delegation system. In addition, the model focuses on privacy and divides the duties with the fewest possible procedures. Moreover, exercising the model’s effectiveness with various circumstances and types of delegates has also been demonstrated.
