When NB-IoT is used to monitor UAVs, developers need to access a UAV via SSH (Secure Shell). However, NB-IoT services are sometimes behind symmetric NAT, and NB-IoT modules can only be controlled by specific AT commands, rendering existing NAT traversal software not applicable. This letter proposes NB-SSH, which provides remote SSH service to UAVs that are behind symmetric NAT. NB-SSH has two variants, in one of which the client side does not need to install any software, and in the other the UAV appears to the client as a neighbor. We implement both variants and evaluate them in a real-world environment.

A data center network often employs a Clos-network structure due to scalability nature. A previous design model analyzed blocking probability to guarantee the quality of Clos network. However, the conditions to guarantee the blocking probability in these models are stringent, which shrinks the switching capacity. This letter proposes a model that relaxes network design constraints to maximize switching capacity while guaranteeing blocking probability in a two-step manner, where the proposed model divides intermediate switches into two groups. Numerical results show that the proposed model achieves a larger switching capacity than a conventional one-step model.

This letter explores the challenges of reliable communication in industrial applications, where human and robot collaboration requires highly reliable communication channels. We propose a hierarchical and distributed approach for solving the dynamic selection of resources. We assign distributed entities to portions of the managed working environment and investigate how to deal with users at their borders, proposing a mechanism to balance performance and resource efficiency. We support our analysis with numerical results obtained by simulation. By properly tuning the algorithm parameters, we can reduce energy consumption while satisfying the same reliability requirements.

Modern radio telescopes utilize IP multicast in their data networks because multicasting offers enhanced flexibility. Telescope data networks carry high volumes of real-time data and need to support network reconfigurability. Hence, they stand to gain from optimized traffic management. Software-Defined Networking (SDN) simplifies and adds dynamism to multicast routing. We reference the MeerKAT radio telescope data network and investigate methods to route the multicast streams in an SDN context. Such route planning is influenced by the telescope control system along with architectural and dynamic (e.g., link or device failure) properties of the network. This letter shows that SDN is a practical option for radio telescope data networks and that the system is flexible, easy to understand, and scalable. Additionally, we present two basic algorithms which can serve as foundational templates for more tailored solutions.

We propose a unicast wireless file-transfer scheme based on fountain coding augmented by a feedback mechanism to help the source make near-optimal transmission decisions. By avoiding wasted transmissions that occur in conventional fountain coding due to the delayed reception of feedback messages, the proposed scheme provides large reductions in the energy expenditure, while keeping the delivery latency very close to its minimum achievable value and avoiding excessive computational overhead. The scheme is robust against feedback message losses and imperfect estimates of system parameters. We demonstrate up to 85% reduction in the energy expenditure compared to conventional fountain coding and similar reductions in the average delivery latency compared to a state-of-the-art method.

The Fifth Generation Communications (5G) has paved the way for various use cases including but not limited to networked robotics and autonomous systems, distributed and collaborative sensor/actuator technologies, personalized user experience and extended reality. 5G networking builds on three pillars to enable the accomplishment of these use cases: enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra reliable low latency communications (URLLC). While 5G has started to become a reality, the applications supported by these enablers require 100 microseconds at peak rate latency, 100 times faster speed and ten times higher penetration per square kilometer. Given these facts, a roadmap for the Sixth Generation Communications (6G) has been laid out aiming at Year 2030.

Extended Reality (XR) is one of the most important 5G/6G media applications that will fundamentally transform human interactions. However, ensuring low latency, high data rate, and reliability to support XR services poses significant challenges. This letter presents a novel AI-assisted service provisioning scheme that leverages predicted frames for processing rather than relying solely on actual frames. This method virtually increases the network delay budget and consequently improves service provisioning, albeit at the expense of minor prediction errors. The proposed scheme is validated by extensive simulations demonstrating a multi-fold increase in supported XR users and also provides crucial network design insights.
