5thGeneration Security and Zero Trust Importance
The expansion of 5G technologies has ushered in a new era of communications with promises for high-speed mobile broadband communications, ultra-low latency applications, massive device connectivity, Internet of Things (IoT) support, and more. As 5G usage and coverage continue to increase in the near future for industries and consumers alike, it also brings with it a new range of security challenges and considerations.

The Probability of Achieving Deadlines in Communication Networks
End-to-end (E2E) delay, which measures the time taken for packets to travel from a source node to a destination node in communication networks, is a widely used performance metric. It is frequently defined as the average delay of packets along a given path.

Cross-Layer Methods for Ad Hoc Networks
The Open systems interconnection (OSI)model used to be a common network model for years. In the case of ad hoc networks with dynamic topology and difficult radio communications conditions, gradual departure is happening from the classical kind of OSI network model with a clear delineation of layers (physical, channel, network, transport, application) to the cross-layer approach. The layers of the network model in ad hoc networks strongly influence each other. Thus, the cross-layer approach can improve the performance of an ad hoc network by jointly developing protocols using interaction and collaborative optimization of multiple layers. The existing cross-layer methods classification is too complicated because it is based on the whole manifold of network model layer combinations, regardless of their importance.

Internet of Things Device Identification and Two-Stage Clustering
Smart home environments, which consist of various Internet of Things (IoT) devices to support and improve our daily lives, are expected to be widely adopted in the near future. Owing to a lack of awareness regarding the risks associated with IoT devices and challenges in replacing or the updating their firmware, adequate security measures have not been implemented. Instead, IoT device identification methods based on traffic analysis have been proposed. Since conventional methods process and analyze traffic data simultaneously, bias in the occurrence rate of traffic patterns has a negative impact on the analysis results.

Intelligent Surfaces in the Terahertz Communication Channel Models
Terahertz (THz) band will play an important role in enabling sixth generation (6G) envisioned applications. Compared with lower frequency signals, THz waves are severely attenuated by the atmosphere temperature, pressure, and humidity. Thus, designing a THz communication system must take into account how to circumvent or diminish those issues to achieve a sufficient quality of service. Different solutions are being analyzed: intelligent communication environments, ubiquitous artificial intelligence, extensive network automation, and dynamic spectrum access, among others.

Multi-Input Multi-Output and Non-Orthogonal Multiple Access
Multi-input multi-output and non-orthogonal multiple access (MIMO-NOMA) Internet-of-Things (IoT) systems can improve channel capacity and spectrum efficiency distinctly to support real-time applications. Age of information (AoI) plays a crucial role in real-time applications as it determines the timeliness of the extracted information. In MIMO-NOMA IoT systems, the base station (BS) determines the sample collection commands and allocates the transmit power for each IoT device.

User Association Performance Trade-Offs in Integrated RF/mmWave/THz Communications
6G and beyond wireless networks will be utilizing RF (below 6 GHz) mm-Wave, and sub THz frequency bands for user access. These three bands, however, have distinct propagation characteristics and bandwidths. Associating users across these bands using available radio resources while meeting different Quality of Services across slices is a difficult optimization problem.
