Popular spreading codes, such as the Walsh-Hadamard code (orthogonal) and maximal length sequence (m-sequence) (semi-orthogonal), suffer from intersymbol interference (ISI). ISI increases owing to the poor autocorrelation properties of the spreading codes, resulting in a deteriorated bit-error-rate (BER) performance. Recently, a cyclic interleaving transmission has been proposed to enhance multipath diversity in the presence of ISI. In this study, an identical code-data cyclic shift (ICDCS) transmission scheme is introduced to achieve improved multipath diversity in time-dispersive channels. The proposed ICDCS transmission is designed based on cyclically shifting identical codes and data. The code and data involved in the first set of spreading are cyclically shifted for the next set of spreading, and the two sets are blended to perform cyclic interleaving. The data are despread from each multipath component at the receiver using different codes derived from a single m-sequence through identical code cyclic shifting (ICCS). Consequently, multipath diversity increases, resulting in a significant reduction in the BER. ICDCS transmission effectively utilizes all multipath components and the codes derived from the ICCS to mitigate ISI. The simulation results confirm that the proposed ICDCS transmission significantly enhances the multipath diversity compared to the conventional cyclic interleaving transmission scheme.","PeriodicalId":23282,"journal":{"name":"Transactions on Emerging Telecommunications Technologies","volume":"35 7","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141435695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 global ledger is updated with transactions using consensus techniques. Consensus algorithms are developed for networks with untrusted nodes to achieve reliability. Academics are paying attention to this technology because it has essential features like decentralization, stability, anonymity, and transparency. Even though the blockchain has some unique features, it has to deal with many challenges and restrictions, such as scalability, security, hidden centrality, and high cost. Artificial intelligence and blockchain are technologies that have been much discussed in the last decade and are developing rapidly. Combining the two to meet the existing challenges can have fascinating results. In this paper, we introduce the novel idea of cognitive blockchain by incorporating intelligent thought into the blockchain. With cognitive capabilities, blockchain technology can perceive the state of the network, analyze the data it has collected, make good decisions, and take appropriate action to improve network performance. We provide an operational framework for cognitive blockchain, which primarily refers to the connections between fundamental cognitive processes, including the perception-action cycle, data analytics, knowledge discovery, intelligent decision-making, and service provision. Then, using learning automata, we provide methods for creating cognitive engines for performance optimization by intelligently adjusting the block size, time interval, and validators in blockchain systems with BFT-based consensus algorithms. Several experiments have been conducted to assess the suggested approaches' effectiveness. The findings demonstrate that the proposed performance optimization approach improves blockchain performance criteria.","PeriodicalId":23282,"journal":{"name":"Transactions on Emerging Telecommunications Technologies","volume":"35 7","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141435694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, it can provide several web-based applications focused on home automation, smart cities, smart agriculture and so forth. In particular, preventing device reputation attacks, which is one of the most significant threats to the WoT, is critical when considering the huge amount of information that is generated, processed and analyzed by the network. There may be situations where intruders deploy fake devices to introduce false information, downgrading the information from valid devices for their own benefits. Different authors have proposed various security methods and algorithms using machine learning, cryptographic or semantics-based methods. However, the existing mechanisms have various limitations in terms of accuracy, storage overhead, and computational/communication overheads, that still need to be addressed. The trusted mechanism can be considered as another way of ensuring security while transmitting the information through the Internet by identifying their legitimacy. Hence, the aim of this article is to propose a secure and trusted WoT framework using similarity index and community of interest similarity score schemes. The proposed mechanism is evaluated against existing schemes that consider both cryptographic and semantic parameters to ensure the security in the network by using metrics such as recommendations, decay time factor, and packet loss recovery rate.","PeriodicalId":23282,"journal":{"name":"Transactions on Emerging Telecommunications Technologies","volume":"35 6","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141326638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, security concerns arise due to the potential life-threatening damage that can be caused by attacks on IoMT devices. To enhance the security of IoMT devices, researchers propose the use of novel artificial intelligence-based intrusion detection techniques. This article presents a hybrid alex net model and an orthogonal opposition-based learning Yin-Yang-pair optimization (OOYO) optimized attention-based Peephole long short term memory (PLSTM) model to distinguish between malicious and normal network traffic in the IoMT environment. To improve the scalability of the model in handling the random and dynamic behavior of malicious attacks, the hyper parameters of the PLSTM framework are optimized using the OOYO algorithm. The proposed model is evaluated on different IoT benchmark datasets such as N-BaIoT and IoT healthcare security. Experimental results demonstrate that the proposed model provides a classification accuracy of 99% and 98% on the healthcare security and N-BaIoT datasets, respectively. Moreover, the proposed model exhibits high generalization ability for multi-class classifications and is effective in reducing the false discovery rate. Overall, the proposed model achieves high accuracy, scalability, and generalization ability in identifying malicious traffic, which can help improve the security solution of IoMT devices.","PeriodicalId":23282,"journal":{"name":"Transactions on Emerging Telecommunications Technologies","volume":"35 6","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141304188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 goal of developing SCC for a community is to encourage people to focus on the present, consider the future, and reflect on the past. In SCC, nodes (vehicles) can use their mobility to collect data from interconnected devices and send it to a variety of delay-tolerant applications. Vehicular delay tolerant networks are an ideal fit for such services. However, the problem is that the devices and nodes (vehicles), having limited resources, may become unwilling to cooperate due to their selfish behavior. This article presents a reliable community card system (RCCS) with two main parts: a reliable community and community-based card tracking system (CBCTS). The reliable community contains all trustworthy vehicles with a certain level of community reputation determined by their honesty level. In CBCTS, every vehicle needs a community card to participate in the network and the neighboring vehicles act as monitoring vehicle. The evaluation results show that the proposed RCCS is quite effective, with detection time and packet delivery. Similarly, it causes minimal overhead and energy consumption compared to all other existing techniques.","PeriodicalId":23282,"journal":{"name":"Transactions on Emerging Telecommunications Technologies","volume":"35 6","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141298349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More specifically, a multi-user untrusted half/full-duplex (HD/FD) uni/bi-directional wireless amplify-and-forward (AF) relay network is studied, adopting orthogonal frequency division multiplexing (OFDM). In order to minimize the information leakage, it is considered that a limited number of friendly jammers affect the untrusted relay. In this context, the achievable secrecy rate of the relay network is theoretically analyzed and optimization problems are formulated and solved for the untrusted relay's location and power allocation. Monte Carlo simulations are conducted to validate the theoretical findings, revealing that channel estimation errors cause coding gain losses for low signal-to noise ratio (SNR) while their impact becomes negligible for high SNR. Also, a large number of user-pairs achieves higher secrecy rate while FD relaying further improves the secrecy performance. Finally, bi-directional relaying provides higher achievable secrecy rate over uni-directional relaying.","PeriodicalId":23282,"journal":{"name":"Transactions on Emerging Telecommunications Technologies","volume":"35 6","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141298350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these diseases, chronic kidney disease (CKD) is a significant contributor to both morbidity and mortality. Integrating the Internet of Things (IoT) and cloud computing in healthcare has gained momentum, particularly in remote patient monitoring. However, it is essential to acknowledge that cloud computing has limitations, particularly in handling vast volumes of Big Data, mainly due to scalability and latency concerns. This article proposes a novel framework, AdaBoostCoTCKD, to mitigate latency issues, minimize response times, reduce power consumption, and optimize network resources for predicting CKD. The framework leverages the synergy between the AdaBoost machine learning technique and fog computing paradigms to enhance the precision and efficiency of CKD prediction methods. In addition, it introduces an auxiliary cloud-based database, enriching the pool of future insights and facilitating prospective database infrastructure expansions. This augmentation is expected to impact predictive accuracy positively. We conducted comprehensive experiments to demonstrate the effectiveness of our approach. Our model achieved an impressive training accuracy of 99.928% and testing accuracy of 99.975%, while the fog environment reduced latency by 31% and energy consumption by 75% compared to traditional cloud-based solutions. Our proposed system enables early CKD detection and offers advantages over cloud-only solutions, providing a robust and efficient platform for healthcare IoT applications with significant clinical value. These promising results underscore the potential of combining fog computing and the AdaBoost machine learning technique to advance healthcare by addressing latency, response time, power consumption, and network resource optimization challenges in CKD prediction.","PeriodicalId":23282,"journal":{"name":"Transactions on Emerging Telecommunications Technologies","volume":"35 6","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141298351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An additional obstacle is how to search for signcrypted cloud data using plaintext keywords. In this paper, we suggest a plaintext-checkable identity-based signcryption for CPS towards IIoT (IBSC-PCE), which enables plaintext searching of signcrypted cloud-based data. We provide both confidentiality and integrity and also demonstrate the security of our approach under the q-Diffie-Hellman inversion problem (q-DHIP).
