The presence of malicious nodes can lead to message transmission and routing disorganisation, and network performance is effectively compromised. Game theory-based fuzzy secure clustering (GTFSC) improves performance metrics in low-scale and high-scale networks. This protocol's novel ability to dynamically scale performance measures as nodes expand improves efficiency and adaptability. While improving performance metrics, the proposed algorithm also efficiently identifies malicious nodes and re-routes the transmission, excluding the found malicious nodes. For any MANET system, secure and successful data transmission is paramount. The proposed protocol integrates various algorithms to fulfil its aim of customised EGT, GWO, and fuzzy clustering. Black hole attacks, grey hole attacks, Sybil attacks, and data tampering attacks are all considered to provide comprehensive attacks on MANET. Every node is assigned trust values, which get updated on data transmission. Fuzzy Clustering is employed to identify malicious nodes. Evolutionary Game Theory (EGT) optimises network organisation by designating cluster heads and clusters as nodes. Additionally, the proposed protocol leverages the Grey Wolf Optimisation Routing Algorithm (GWO), which establishes efficient routes from the source to the sink node. The analysis result shows maximum performance with a packet delivery ratio of around 98%, throughput of 90% end-to-end delay reduced by 15%, and energy consumption reduced by 18%, respectively, compared to an existing protocol.","PeriodicalId":51726,"journal":{"name":"IET Wireless Sensor Systems","volume":"14 6","pages":"451-476"},"PeriodicalIF":1.5,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/wss2.12095","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143248868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adversary links often degrade distributed recovery algorithm performance in distributed estimation. The authors propose secure distributed estimation algorithms employing an adaptive kernel and adaptive combination coefficients derived from it. The authors’ method includes a multiple kernel approach with varied widths and a heuristic formula for combination coefficients, improving performance in the presence of adversary links. Additionally, the approach is extended to single exponential kernels with fixed and adaptive widths, treating them as special cases. The multiple kernel method is used because it provides more degrees of freedom compared to a single kernel, leading to better results. Simulation results show that the proposed multiple kernel approach achieves performance close to the diffusion least mean square algorithm in the absence of attacks. The adaptive nature of the kernel and coefficients enhances algorithm robustness, making it promising for secure distributed estimation in the presence of adversary links.","PeriodicalId":51726,"journal":{"name":"IET Wireless Sensor Systems","volume":"14 6","pages":"477-483"},"PeriodicalIF":1.5,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/wss2.12096","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143252966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the most pressing concerns is user authentication, which was originally intended to prevent unwanted access to critical information but has since expanded to provide tailored service customisation. We suggest a Wi-Fi sensing-based physical layer authentication method for IoT networks to solve this problem. Our proposed method makes use of raw channel state information (CSI) data from Wi-Fi signals to create a hybrid deep-learning model that combines convolutional neural networks and long short-term memory networks. Rigorous testing yields an astonishing 99.97% accuracy rate, demonstrating the effectiveness of our CSI-based verification. This technology not only strengthens wireless network security but also prioritises efficiency and portability. The findings highlight the practicality of our proposed CSI-based physical layer authentication, which provides lightweight and precise protection for wireless networks in the IoT.","PeriodicalId":51726,"journal":{"name":"IET Wireless Sensor Systems","volume":"14 6","pages":"441-450"},"PeriodicalIF":1.5,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/wss2.12093","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143252444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diverse techniques have been described in the literature to improve indoor localisation services, but their accuracy is significantly affected by the number and location of the anchors, which act as a reference point for localising tags in a given space. The authors focus on indoor area-based localisation. A set of anchors defines certain geographical areas, called residence areas, and the location of a tag is approximated by the residence area in which the tag is placed. Hence the position is not given by exact coordinates. In this approach, placing the anchors such that the resulting residence areas are small on average yields a high-quality localisation accuracy. The authors’ main contribution is the introduction of a discretisation method to calculate the residence areas for a given anchor placement more efficiently. This method reduces the runtime compared to the algorithms from the literature dramatically and hence allows us to search the solution space more efficiently. The authors propose APOTSA, a novel approach for discovering a high-quality placement of anchors to improve the accuracy of area-based indoor localisation systems while requiring a shorter execution time than existing approaches. The proposed algorithm is based on Tabu search and optimises the localisation accuracy by minimising the expected residence area. APOTSA's localisation accuracy and time of execution are evaluated by different indoor-localisation scenarios involving up to five anchors. The results indicate that the expected residence area and the time of execution can be reduced by up to 9.5% and 99% compared to the state-of-the-art local search anchors placement (LSAP) algorithm, respectively.","PeriodicalId":51726,"journal":{"name":"IET Wireless Sensor Systems","volume":"14 6","pages":"427-440"},"PeriodicalIF":1.5,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/wss2.12092","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143248642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An end-to-end architecture is proposed to facilitate real-time digital dashboards to visualise general anxiety risks of patients, especially during a pandemic, such as COVID-19. To collect physiological data related to anxiety (heart rate, blood pressure, and saturation of peripheral oxygen [SPO2]) and communicate them to a centralised dashboard, dubbed ‘X-DASH’, a hardware prototype of the proposed architecture was developed using Node-MCU and diverse sensors. The dashboard presents a smart categorisation of users' data, assessing their anxiety risks, to provide medical professionals and state authorities a clear visualisation of health risks in populations belonging to different regions. We categorised the risk levels as Normal, Mild, Moderate, Elevated, Severe, and Extreme, based on the collected physiological data and pre-defined threshold values. The developed hardware prototype in this work was used to collect data from about 500 patients present at cardiac clinic of a leading general hospital in Karachi (Pakistan) and the anxiety risk levels were assigned based on pre-defined threshold values. To validate the reliability of the X-DASH, the personal physician of each patient was consulted and was requested to identify each of their anxiety risk levels. It was found that the risk levels suggested by X-DASH, (based on data of heart rate, blood pressure, and SPO2 were more than 90% accurate when compared with diagnoses of physicians. Subsequently, packet loss, delay and network overhead for the platform was compared when using MQTT, CoAP and Modbus. Although MQTT has shown higher delays, but it is still recommended due to having a higher reliability.","PeriodicalId":51726,"journal":{"name":"IET Wireless Sensor Systems","volume":"14 6","pages":"396-409"},"PeriodicalIF":1.5,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/wss2.12090","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143252789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Addressing this challenge, the authors’ study focuses on very short-term solar irradiance (SI) prediction.

To achieve accurate very short-term SI predictions, the authors employ machine learning techniques throughout the forecasting process. Additionally, the authors’ work pioneers the integration of the Internet of Things (IoT) into solar power systems, a novel approach in the field. The authors leverage LoRa (long range) technology for low-cost, low-power, and long-range wireless control networks. The authors’ study focuses on SI forecasting using long short-term memory and bi-directional long short-term memory (Bi-LSTM) models, achieving high accuracy. The SI forecasts are evaluated in terms of root-mean-square error (RMSE) and mean absolute error in relation to meteorological data and sky image data. The improvement in performance can be attributed to the Bi-LSTM's bidirectional nature, allowing it to incorporate future information during training, thereby enhancing its predictive capabilities. Overall, the results suggest that the Bi-LSTM model is more suitable for accurately forecasting SI, particularly in scenarios requiring short-term predictions based on rapidly changing environmental factors.","PeriodicalId":51726,"journal":{"name":"IET Wireless Sensor Systems","volume":"14 6","pages":"381-395"},"PeriodicalIF":1.5,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/wss2.12088","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143252518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main objective is to minimise the combined latency of various servers while complying with network limitations. The delay of each server is represented by a non-linear function that has exponentially based. This characteristic inherently brings non-convexity into the objective function. In contrast, the constraints comprise various linear combinations of network variables, including resource block allocations, power consumption, and number of virtual machines. The purpose of these constraints is to guarantee that the allocation of resources adheres to practical limitations and upholds fairness among servers. Nevertheless, the inclusion of a non-convex objective function significantly adds complexity to the optimisation problem and non-convex behaviour, requiring specialised algorithms and techniques to identify solutions. Subsequently, the Lagrange multiplier method has been used to solve this problem mathematically. Numerically, three algorithms have been utilised and compared to solve the problem, these are active-set, interior point and sequential quadratic programming. Note that the total delay as an objective function is based on the total power consumption of the servers. Previous to optimising the total delay, a delay model is proposed and compared with two research works that are based on experimental and real time data. The proposed model shows data matching with the other works and permits for more adaptation/integration with any other works that uses different servers’ characteristics and network parameters.","PeriodicalId":51726,"journal":{"name":"IET Wireless Sensor Systems","volume":"14 6","pages":"528-538"},"PeriodicalIF":1.5,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/wss2.12087","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143253711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
