These objects collaborate to deliver ubiquitous services based on the user mode and context. For more real-time applications, IoT is integrated with quantum computing technologies and tools for enhancing the conventional structure into more different aspects, revolutionizing the processing speed, enhancing communication, and increasing security features. All these objects are equipped with sensors that collect real-time data from their surroundings and share it with neighboring objects. This data is then broadcast into the environment, enabling users to access services without understanding the underlying complex and hybrid IoT infrastructure of heterogeneous devices. These minute and plugable sensors are capable of data collection and are always busy handling data management. However, these sensors often have limited resources, creating significant issues when dealing with massive and repetitive operations. Most of the time, these low-energy sensors are busy with excessive sensing and broadcasting, resulting in overhearing and passive listening. These factors not only create congestion on communication channels but also increase delays in data transmission and adversely affect system performance. To assess the network traffic for securing the IoT resources in the quantum computing environment, in this research work, we have proposed a novel scheme called “Self-Adaptive and Content-Based Scheduling (CACS) for Reducing Idle Listening and Overhearing in Securing the Quantum IoT Sensors”. This scheme reduces idle listening and minimizes overhearing by adaptively configuring network conditions according to the contents of sensed data packets. It minimizes extensive sensing, decreases over-cost processing, and reduces frequent communication that lessens the overall system traffic and secures the resources from being overwhelmed. The simulation results demonstrate a 0.80% increase in delay across various baud rates, resulting in a general increase of 0.44 s. Moreover, it ensures a notable 22.23% reduction in BER and lowers energy consumption by approximately 20%, which is actual energy enhancement in the connected system.</p></div>","PeriodicalId":29968,"journal":{"name":"Internet of Things","volume":null,"pages":null},"PeriodicalIF":6.0,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141952516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paradigm has proven to be highly useful in a wide range of domains where both delay and cost were important metrics. Notably, the Internet of Things (IoT) strongly benefits from this, as small devices can gain access to strong computation power quickly and at a low cost. To achieve this, task offloading is used to decide which task should be executed on which node. The development of an efficient algorithm to address this problem could significantly enhance the sustainability of systems in various industrial, agricultural, autonomous vehicle, and other domains. This paper proposes a new variant of the Niche Pareto Genetic Algorithm (NPGA) called Local search Drafting-NPGA (LD-NPGA) to optimize resource allocation in a Cloud/Fog environment, with the objective of minimizing makespan and cost simultaneously. It generates Pareto solutions allowing the user to make choices closer to its intentions. Thus, it addresses various shortcomings identified in the state of the art, including scalability and aggregation formula. A drafting step is implemented to maintain diversity in the population of solutions, resulting in a more varied Pareto set than basic NPGA. LD-NPGA significantly outperforms state-of-the-art metaheuristics in makespan and cost by 15%. Finally, the scalability of our approach and the variety of solutions generated are confirmed in the different experiments.</p></div>","PeriodicalId":29968,"journal":{"name":"Internet of Things","volume":null,"pages":null},"PeriodicalIF":6.0,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141952841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a priority for new testing frameworks to keep up with the increasing complexity of decision-making, connectivity, data interchange, and data transmission speed. Traditional vehicle testing tools and methods cannot meet the new testing requirements imposed by the upgrading of autonomous driving (AD) technology. They are expensive, time-intensive, and present safety hazards during testing, as well as cannot simulate hybrid real-world situations and manage real-time data efficiently. Therefore, in terms of test efficiency, cost, and safety, a smart vehicle testing in hybrid reality and evaluation method based on a digital twin (DT) is presented to speed up the development and testing of AD functions. Our model uses three-dimensional coordinate mapping, a collision detection model, and virtual scene registration to plot the AD information in the actual environment to the virtual scenario. In addition, the consistent mixed reality-based AD test model is constructed at the same time. Using this model, we demonstrated that our proposal allows for better performance of an AD test. Furthermore, the collision test demonstrates that the mixed reality system has interactive features. The performance of the system under the sampling rate of 50 ms, 200 ms, and 800 ms is compared and analyzed. Also, the experiments show that the algorithm described in this paper works better when the sampling frequency is 200 ms or more.</p></div>","PeriodicalId":29968,"journal":{"name":"Internet of Things","volume":null,"pages":null},"PeriodicalIF":6.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141840914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In considered system, a base station (BS) transmits confidential information for individual IoT users using the short-packet communication technique under the wiretap of eavesdroppers. To enhance physical layer security, the BS injects additional dedicated AN symbols to degrade the information retrieval ability at eavesdroppers. In this paper, we aim to joint design the transmit beamforming and AN symbol to maximize the minimum URLLC secrecy rate of IoT user subject to the power budget of the BS. The optimization design problem is highly nonconvex due to coupled variables in the URLLC secrecy rate and channel dispersion expressions, and thus it is mathematically challenging to solve this problem directly. To overcome this issue, we first introduce various convex inner approximations to convexify the nonconvex terms, and then we develop an efficient iterative algorithm based on the sequential convex programming approach. Extensive numerical simulation results are conducted to investigate the URLLC secrecy rate region. In conclusion, the two new URLLC parameters, i.e., the transmit packet blocklength and block error probability, will cause the considerable degradation on the URLLC secrecy rate region when comparing to that of the traditional beamforming design based on the Shannon capacity.</p></div>","PeriodicalId":29968,"journal":{"name":"Internet of Things","volume":null,"pages":null},"PeriodicalIF":6.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141851438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study presents the Fog Node Selection Engine (FNSE) as an intelligent and reliable fog node selection framework to select appropriate and reliable fog nodes in a trustworthy manner. The FNSE predicts the trust value of fog nodes to help the fog consumer select a reliable fog node based on its trust value. We propose three AI-driven models within the FNSE framework: FNSE based on fuzzy logic (FL), FNSE based on logistic regression (LR), and FNSE based on a deep neural network (DNN). We implement these three models separately using MATLAB for FL and Python for LR and DNN. The performance of the proposed models is compared based on the performance metrics of accuracy, precision, recall, F1 score and execution time. The experiment results show that the FL-based FNSE approach achieves the best performance with the highest accuracy, precision, recall, and F1 score values.
