Special Issue Information

Dear Colleagues,

Wireless networks are rich in data, where data are continuously gathered from a massive amount of user devices and network entities in the form of radio and system measurements. However, the traditional communication protocols considered such data as a short-lived localized commodity due to ageng and user mobility. Hence, drives little insight from such data and results in reactive systems. Recently, the exploration of AI and learning techniques in the field of wireless communication has gained interest and researchers are exploring different techniques to shift the traditional reactive wireless networks to proactive networks. The application of AI in wireless networks provides an opportunity to exploit wireless data in multiple dimensions and create data-driven wireless networks that are more robust and autonomous in changing environments.

This Special Issue encourages the submission of high-quality, innovative, and original contributions of papers dealing with the application of AI in wireless networks. Submission is expected to focus on different verticals of wireless network and future 6G use-case scenarios and propose new solutions, experiment or review current trends, discuss the potential open challenges, etc.

Potential topics include, but are not limited to:

  • AI for Physical and MAC layer protocols
  • Application of AI in Radio Resource and Interference Management
  • AI for Localization Techniques in Wireless Networks
  • Application of AI for Wireless Security and Privacy
  • AI techniques for Cellular LPWAN
  • AI techniques for multi-interface wireless network
  • The application of AI in Connected Vehicles, smart healthcare, and smart cities uses cases from the perspective of wireless communication.
  • Self-organizing networks
  • Trails, testbed, and experiments

The traditional spectrum sensing algorithm based on deep learning requires a large number of labeled samples for model training, but it is difficult to obtain them in the actual sensing scene. This paper applies self-supervised contrast learning in order to solve this problem, and a spectrum sensing algorithm based on self-supervised contrast learning (SSCL) is proposed. The algorithm mainly includes two stages: pre-training and fine-tuning. In the pre-training stage, according to the characteristics of communication signals, data augmentation methods are designed to obtain the pre-trained positive sample pairs, and the features of the positive sample pairs of unlabeled samples are extracted by self-supervised contrast learning to obtain the feature extractor. In the fine-tuning stage, the parameters of the feature extraction layer are frozen, and a small number of labeled samples are used to update the parameters of the classification layer, and the features and labels are connected to get the spectrum sensing classifier. The simulation results demonstrate that the SSCL algorithm has better detection performance over the semi-supervised algorithm and the traditional energy detection algorithm. When the number of labeled samples used is only 10% of the supervised algorithm and the SNR is higher than −12 dB, the detection probability of the SSCL algorithm is higher than 97%, which is slightly lower than the supervised algorithm.

In optimization of wireless networks, path loss prediction is of great importance for adequate planning and budgeting in wireless communications. For efficient and reliable communications in the tropics, determination or estimation of channel parameters becomes important. Research for this article employed different machine learning techniques—AdaBoost, support vector regression (SVR), and back propagation neural networks (BPNNs)—to construct path loss models for Akure metropolis, Ondo state, Nigeria. An experimental measurement campaign was conducted for three different broadcasting stations (Ondo State Radiovision Corporation (OSRC), Orange FM, and FUTA FM) all situated within Akure metropolis. Furthermore, we designed machine learning-based models for path loss prediction at various observation points at a particular frequency, and demonstrated how these algorithms agree with the measured data. For instance, for OSRC (operating at 96.5 MHz) measurement, the RMSEs (root mean square errors) of AdaBoost, SVR, BPNN, and the classical model (log-distance model) predictors were 4.15 dB, 6.22 dB, 6.75 dB, and 1.41 dB, respectively. Additionally, path loss prediction at a new frequency according to the available data at specific frequencies was evaluated. In order to resolve the challenge of limited or insufficient samples at a new frequency, a framework hybridizing classical models and machine learning algorithms was developed. The developed framework employs estimated values that are computed by the classical model based on the prior information for the training set expansion. Performance evaluation of the framework was conducted using measured data of Orange FM (94.5 MHz) and FUTA FM (93.1 MHz), and the samples computed from the classical model were used as training datasets for path loss prediction at a new frequency. RMSEs of AdaBoost, SVR, BPNN, and log-distance predictors were 1.77 dB, 1.52 dB, 1.45 dB, and 2.61 dB, respectively. However, adding measured data generated by the classical-based model, the RMSEs of AdaBoost, SVR, BPNN, and log-distance algorithms were 1.81 dB, 1.63 dB, 1.45 dB, and 1.88 dB, respectively. The results demonstrate how the proposed sample expansion framework enhances prediction performance in the scenario of few measured data at a new frequency. Finally, these results are promising enough for the deployment of the proposed technique in practical scenarios. Full article

A traditional centralized method of training AI models has been put to the test by the emergence of data stores and public privacy concerns. To overcome these issues, the federated learning (FL) approach was introduced. FL employs a privacy-by-design architecture to train deep neural networks utilizing decentralized data, in which numerous devices collectively build any machine learning system that does not reveal users’ personal information under the supervision of a centralized server. While federated learning (FL), as a machine learning (ML) strategy, may be effective for safeguarding the confidentiality of local data, it is also vulnerable to attacks. Increased interest in the FL domain inspired us to write this paper, which informs readers of the numerous threats to and flaws in the federated learning strategy, and introduces a multiple-defense mechanism that can be employed to fend off threats.
