Goal-oriented communication is a promising approach to tailor the network resource management algorithms to the needs of particular applications, thus enhancing the efficiency of resource utilization and boosting the application performance. In the context of distributed cyber-physical systems and networked controlsystems, the design of a control-aware transport layer (TL) represents a realistic approach for goal-oriented communications since it can be integrated into generic control setups without making assumptions on particular hardware or network technologies and deliver enhanced end-to-end performance. This demo showcases the application performance of different TL schemes used for communication between the sensors and the controllers monitoring and actuating inverted pendulums, i.e., multi-dimensional plants. The nodes of the control loops are realized with Zolertia Re-Mote devices, and multiple control loops communicate over the shared wireless network using IEEE 802.15.4 standard. We use the demonstration testbed to compare the performance of conventional, state-of-the-art, and novel goal-oriented TL schemes by observing the emulated dynamics of inverted pendulums.

The flexible job-shop problem is one of the classical problems that have attracted much attention in the field of industrial automation and control. For the Multi-Objective Flexible Job-shop Scheduling Problem (MOFJSP), this paper proposes a hybrid particle swarm Non-dominated Sorting Genetic Algorithm ii (NSGA-ii) to solve the problem. The high-quality solution of the problem is obtained through particle swarm optimization as part of the initial population of NSGA-ii, and an elite strategy is used to prevent the loss of outstanding individuals by mixing all the individuals of the parent and the offspring in a non-dominated sorting method. This approach not only facilitates automation in manufacturing and production but also enhances the control and optimization of complex systems. Furthermore, integrating intelligent transportation systems and the internet of Things (IoT) into the scheduling process ensures real-time fault diagnosis and fault-tolerant control, thereby improving the overall efficiency and reliability of the production system. The experimental results show that the hybrid optimization approach combining PSO and NSGA-ii exhibits superior performance in solving MOFJSP. This research contributes to the advancement of cyber-physical systems and the automation of complex industrial processes.

In recent years, the adoption of Machine Learning, particularly Reinforcement Learning (RL), for the control and management of communication networks has emerged. However, a critical challenge hindering its practical implementation is the lack of explainability inherent in these models, which prevents network administrators from adopting these techniques despite their great potential to improve networkperformance. This paper aims to enhance the trustworthiness of RL-based network management and control, by making the RL model explainable and providing administrators with transparent insights into the RL decision-making processes. With this aim, we propose a methodology that leverages surrogate models, specifically, Decision Trees (DTs), to create simplified yet interpretable representations of the original RL model, able to explain it. Experiments were conducted to evaluate the efficacy of our method, demonstrating that the surrogate model achieves about 94% accuracy in imitating the original RL model. Additionally, the surrogate model significantly improves the explainability of the entire system by automatically generating graphical representations, in the form of DTs for interpreting the RL decisions.

This paper presents a holistic approach for transmitting arbitrary data to local internet-of-Things (IoT) devices using only public services in a zero-trust environment. The approach features a variety of benefits, namely (i) eliminates the need for service providers to deploy their own costly infrastructure, (ii) enables the receiving device to operate without an active network connection, (iii) ensures that the data can be proven untampered on the IoT device itself, (iv) verifies both the validity and recency of the information, (v) requires low administrative and technical efforts, (vi) allows for wireless data updates, including the timeliness of current information, by any participant due to the zero-trust assumption. The described methodology utilizes distinct features of Proof-of-Work (PoW)-based programmable blockchain systems. This work will focus on the usage of Ethereum Classic (ETC) as base layer for trust, the validity and recency of the information. The proposed approach has wide-ranging practical applications, including programmable, rule-based locking systems such as smart locks used in corporate and institutional buildings, cars, and hotels. It also facilitates other forms of access control, such as ticket systems, health certificates, and proof-of-possession for resources or achievements. Due to the zero-trust assumption, data updates as well their recency can be updated by any participant of the system.

This paper proposes a framework for controlling a drone swarm to achieve two goals: i) covering a desired region of interest through onboard cameras that capture videos to be sent in real-time to a Ground control Station (GCS), and ii) ensuring the highest video quality possible given the available internetnetwork bandwidth. Indeed, the quality of received videos depends on both the available bandwidth, which directly influences video encoding bitrate, and the altitude of drones, which influences pixel density. Thus, contrary to the conventional assumption of uniform drone altitudes, we let drones to track a reference altitude that is function of the time-varying available bandwidth to improve visual quality. To achieve the aforementioned goals, we propose a leader-follower multi-agent system formation control problem. In this setup, the leader tracks a desired path using Nonlinear Model Predictive control (NMPC) to cover the area of interest. Follower agents track the leader using NMPC, aiming at maximizing both the total coverage area and the quality of the videos sent to the GCS, considering the constraints imposed by the network available bandwidth. At the same time, we formulate the NMPC problem to ensure that the swarm maintains a formation characterized by a given overlap percentage between the videos captured by the drones while avoiding collisions. This allows dynamical stitching of the received videos at the GCS, enabling the execution of computer vision algorithms for tasks such as object detection and surveillance.
With the continuous development of mobile internet technology, its demand for networkperformance is also increasing. Although the traditional multi-level structure of network resources enhances the scalability and in...

The effective deployment of wireless sensor networks (WSNs) is a crucial foundation for the intelligent development of power systems. To address the optimization of wireless sensor distribution in power systems, this paper proposes a novel method named the Distributed Particle Swarm Optimization algorithm (D-PSO). This method mitigates the premature convergence issue of heuristic algorithms by introducing a regional operator. Additionally, considering the high-interference environment in power systems, relay node strategy (RNS) is incorporated to ensure communication quality. Simulation results validate the effectiveness and superiority of the D-PSO method and demonstrate the necessity of the RNS. Compared to some advanced particle swarm algorithms, this method better balances energy consumption, coverage, and communication quality, thereby significantly enhancing the overall performance of the wireless sensor network.
