A cross-layer simulator for industrial wireless communication systems
No full texthe paper presents a network simulator specifically
designed for the analysis of real-time wireless networks in
an industrial control context, and for time-space localization
applications. Critical issues associated to physical components
are accounted for, together with the performance of the commu-
nication channel in an interfering environment. A comparison
toward already available simulation schemes is provided in order
to show the importance associated to the above aspects in the
accuracy of simulation results. In particular, it is seen that
random processing delays and an accurate implementation of
communication protocol models both represent critical aspects
that deeply affect accuracy. Real-life experiments support the
models and the theory discusse

No full textBridging real-time CAN networks with in-vehicle single pair ethernet: A time-sensitive networking approach
No full textThis paper explores the challenges of integrating existing in-vehicle networks (IVNs) with Ethernet, explicitly focusing on the coexistence of traditional Controller Area Network (CAN) systems with Single Pair Ethernet (SPE) and Time-Sensitive Networking (TSN). The research presents an experimental setup using real hardware to simulate a zonal vehicle architecture, where CAN nodes are integrated into the in-vehicle Ethernet network. The approach utilizes a gateway implemented on a TSN-enabled switch, facilitating seamless connectivity between the real-time CAN network and the TSN-enabled in-vehicle Ethernet. The study demonstrates the feasibility of combining real-time CAN traffic with high-bandwidth Ethernet traffic through the integrated gateway. It also emphasizes the crucial role of TSN features in maintaining the real-time properties of the CAN network, even in the presence of additional traffic loads

Packet Losses Distributions in 5G Networks for PMU-Based Monitoring Systems
No full textThe rapid shift toward digitalization of electrical substations, has pushed research interest toward the analysis of feasibility in using low latency and high reliability communication infrastructure. In particular, the adoption of 5G networks in Phasor Measurement Units (PMUs) within the framework of IEC 61850 digital substations has shown promising results. Building upon this, in this paper we address the critical issue of packet loss. Based on a real distribution network, we analyze packet loss patterns their time distribution. The results provides valuable insights into the reliability of the communication network analyzing the behavior of the network in different scenarios involving changes in the number and positioning of gNBs. This work can represent a foundation for improving robustness and reliability of 5G-base real-time PMUs systems
Banco di prova efficace ed economico per la valutazione in pre-compliance di emissioni irradiate nella banda 2-8 GHz
No full textCon il presente lavoro si intende presentare un sistema
per effettuare misure di emissione irradiata
ad alta frequenza (banda 2 – 8 GHz) in precompliance,
ovvero senza le restrizioni normative
sul sito di prova. Questo sistema presenta delle
caratteristiche molto interessanti di ripetibilità della
misura. Lo scopo del sistema
proposto è di permettere al progettista che abbia
già individuato le criticità del proprio circuito in
termini di emissioni irradiate, di effettuare in modo
rapido ed economico delle misure di emissione
per valutare l’efficacia delle soluzioni adottate per
la riduzione dei disturbi
