In wireless communication governed by the IRS, the acquisition of channel state information (CSI) is essential for designing the optimal beamforming. However, acquiring the CSI is difficult as the IRS does not have radio frequency chains to transmit/receive signals and the capability to process the signals is also limited. The cascaded channel linking the base station (BS) and a user through the IRS does not necessarily adhere to a specific channel distribution. Conventional and deep learning-based techniques for channel estimation face challenges: the pilot overhead and compromised estimation accuracy due to assumptions of prior channel distribution and noisy signal. To overcome these issues a novel generative cascaded channel estimation (GCCE) model based on a generative adversarial network (GAN) is proposed to estimate the cascaded channel. The GGCE model reduces the reliance on pilot signals, effectively minimizing pilot overhead, by deriving CSI from received signal data. To enhance the estimation accuracy, the channel correlation information is provided as a conditioning factor for the GCCE model. Additionally, a denoising network is integrated into the GCCE framework to effectively remove noise from the received signal. These integrations collectively enhance the estimation accuracy of the GCCE model compared to the initial GAN setup. Experimental results illustrate the superiority of the proposed GCCE model over conventional and deep learning techniques when provided with the same pilot count.</p>","PeriodicalId":23750,"journal":{"name":"Wireless Networks","volume":"62 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140057510","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 maintain the security and privacy of the real-time health information of the users or patients, the proper mutual authentication and key agreement (AKA) is the foremost necessity. In this context, Shadi Nashwan proposed an end-to-end authentication scheme for a healthcare IoT system i.e. WMSN, and claimed that their scheme could resist so many existing possible threats and could maintain a low computational cost too. Unfortunately, during this research, it is found that their scheme can be threatened by eavesdropping and jamming/desynchronization attacks and have many computational flaws, as well. Moreover, they also assumed that the gateway node (GWN) is always trustworthy, but in reality, it is not always feasible, as the GWN may act as a local server. Hence, in this article, a new AKA scheme has been proposed using the user’s physiological information like ECG data in order to make the WMSN more secure and reliable. In addition, the proposed scheme can resist many well-known threats like GWN spoofing attack, key escrow problem and can guard against GWN stolen database problem, also. To proof the superiority of the proposed scheme, the informal and formal security analysis have been performed using automated validation of internet security protocols and applications (i.e. AVISPA) and Burrows–Abadi–Needham (BAN) logic, respectively. Based on the comparative study with existing schemes concerning security features, computational and communicational cost, and storage requirement; the proposed scheme can perform better than the existing schemes and well suitable for practical implementations.</p>","PeriodicalId":23750,"journal":{"name":"Wireless Networks","volume":"31 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140045386","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}

Currently, in the case of Internet of Things devices is especially relevant, because they usually have access to the Internet, although in many cases they are vulnerable to these phishing attacks. This paper offers an overview of the most relevant techniques for the accurate detection of fraudulent URLs, from the most widely used machine learning and deep learning algorithms, to the application, as a proof of concept, of classification models based on quantum machine learning. Starting from an essential data preparation phase, special attention is paid to the initial comparison of several traditional machine learning models, evaluating them with different datasets and obtaining interesting results that achieve true positive rates greater than 90%. After that first approach, the study moves on to the application of quantum machine learning, analysing the specificities of this recent field and assessing the possibilities it offers for the detection of malicious URLs. Given the limited available literature specifically on the detection of malicious URLs and other cybersecurity issues through quantum machine learning, the research presented here represents a relevant novelty on the combination of both concepts in the form of quantum machine learning algorithms for cybersecurity.

The routing process is challenging due to the constrained energy resources and transmission bandwidth. The conventional strategies possess shortcomings, like, as high computing complexity, extensive problem-solving time, complexity in achieving optimal values, and ease of falling into local solutions. Hence, the aim is to propose a hybrid metaheuristic algorithm, known as a multi-objective optimized multi-path and multi-hop routing algorithm (MMMRA). It incorporates the chimp optimization algorithm (COA) for determining the optimal multi-path route based on multi-objective function and ant colony optimization for determining the optimal multi-hop routing. The proposed MMMRA is implemented using NS-2 and to evaluate the performance, nine various scenarios are considered. The MMMRA is validated using different performance measures and compared with other benchmark algorithms. The simulation results indicate that the MMMRA exhibits percentage improvement in terms of residual energy by 1.63%, 4.96%, 6.89%, 7.51%, and 9.67% over IPSMT, BIM2RT, SCP, PSOBS, and RDICMR algorithms respectively. Moreover, the HND and FND of the MMMRA algorithm perform better in all three scenarios (center, corner, and outside positions of sink node), especially when the sink node is placed at the center position, the HND of MMRA shows a percentage improvement by 24% and 12.73% over IPSO–GWO, and COA–HGS algorithms respectively.

Recently, it has been found that surrogate-assisted meta-heuristic algorithms show potential in solving expensive complex optimization problems. This paper proposes an efficient surrogate-assisted Taguchi salp swarm algorithm (SATSSA) to solve expensive complex optimization problems. The SATSSA uses a combination of the local surrogate-assisted model (LSAM), global surrogate-assisted model (GSAM), and k-means clustering surrogate-assisted model (KCSAM) to fit the fitness function. To enhance the prediction ability of the model, an improved salp swarm algorithm with the Taguchi method (TSSA) is proposed to update and predict the model. GSAM is mainly used to capture the entire landscape of the search space. KCSAM is designed to capture part of the search space to improve the exploration capability of the algorithm. LSAM is used to capture the contours around the optimal individual. The proposed SATSSA is compared with other four excellent algorithms on 30D, 50D, and 100D benchmark functions. In addition, SATSSA is also applied to intrusion detection.

A number of trust systems have been proposed, but most of them are not adaptative to the current state of network security and the intensity of the attacks to which they are subjected, especially in the case of collaborative attacks. They employ fixed trust metrics derived from expert opinion rather than the objective method based on the network’s current security level. Furthermore, they are complex trust systems designed for a specific application with a high attack probability. Thus, even with a low attack rate, they consume a lot of energy. This paper proposes an adaptive trust system that considers both the network’s risk level and the trust values of sensor nodes at the same time. To match the situation in the network, the proposed system employs various trust policies. In risky situations where the WSN environment remains untrustworthy, the proposed system adjusts its trust metrics based on the network attack intensity. When the attacks are eliminated and the misbehavior rate is low, the system switches to an energy efficient policy and adjusts its trust metrics to conserve sensor node energy. Simulation results show that a zero-tolerance policy achieves 95% of the detection rate and conserves 50% of nodes’ energy under the presence of 35% of malicious nodes in the network. Energy efficient policy achieves 90% of detection rate and conserves 95% of nodes’ energy under the existence of 10% of malicious nodes in the network.
