Journal of Electrical and Computer Engineering, 2026
The Internet of Things (IoT) has emerged as a large‐scale ecosystem that integrates sensing, communication, and computation across diverse application domains. Its deployment spans smart homes, wearable devices, industrial automation, and smart cities, where heterogeneous devices are required to operate under strict performance, reliability, and resource constraints. This paper presents a comprehensive review of IoT systems, with a particular focus on architectural models, application domains, communication technologies, signal processing techniques, and deployment challenges. Rather than providing a high‐level overview, the paper examines how architectural design choices, communication mechanisms, and signal processing strategies jointly influence overall system performance. Key challenges—including availability, reliability, mobility support, scalability, interoperability, energy efficiency, security, and privacy—are analyzed from a system‐level perspective. Unlike existing surveys that address isolated aspects of IoT, this work emphasizes cross‐layer interdependencies, highlighting how constraints at one layer propagate to others. The objective is not to propose new solutions but to consolidate existing research, clarify persistent limitations in current IoT deployments, and identify future research directions toward more robust and efficient IoT systems.
Optimizing QoS MAC Scheduling in 5G NR: A Lyapunov Approach Evaluated With XR Traffic
Neco Villegas, Ana Larrañaga, Luis Diez, Katerina Koutlia, Sandra Lagén, Ramón Agüero
IEEE Transactions on Network and Service Management, 2026
5G and beyond technologies are designed to convey multiple QoS requirements coming from highly heterogeneous services. In this regard, 5G extends the QoS definition of previous technologies. In order to fulfill the requirements of new services, it is necessary to develop resource management solutions that effectively and efficiently translate them to usage of resources. Therefore, MAC schedulers are to be designed to accommodate the demands of emerging applications with stringent QoS requirements, such as XR. In this work, we introduce a Lyapunov-based MAC scheduler designed to appropriately tackle coexisting heterogeneous QoS flows. The proposed approach allows the implementation of policies that explicitly consider the QoS requirements, as well as an efficient use of allocated resources. The results obtained through extensive experiments over the ns-3 5G-LENA simulator demonstrate that our scheduler guarantees the required time-average bit rate for every QoS flow at every time window, while ensuring the stability of traffic queues for all users.
ISAC-Assisted DRL for Dynamic MAC Scheduler Reconfiguration in O-RAN
Neco Villegas, Juan Luis Herrera, Luis Diez, Domenico Scotece, Luca Foschini, Ramón Agüero
IEEE Open Journal of the Communications Society, 2026
This paper introduces reconfiguration mechanisms for a 5th Generation (5G) Medium Access Control (MAC) scheduler, which uses Deep Reinforcement Learning (DRL) and is deployed as an <italic>xApp</italic> within the RAN Intelligent Controller (RIC) framework. The objective is to optimize the allocation of radio resources in 5G networks, seeking to meet Quality of Service (QoS) requirements while minimizing resource consumption. To this end, we propose the dynamic adjustment of configurable parameters in a Lyapunov-based scheduler, which addresses the challenges posed by the highly dynamic network environment, and the need to meet multiple QoS objectives. The DRL agent dynamically reconfigures the scheduling by leveraging Integrated Sensing and Communications (ISAC)-provided sensing data alongside conventional communication metrics. Exploiting the adaptability of DRL, our solution can effectively respond to fluctuating network conditions, thereby continuously enhancing scheduling decisions in real time. The proposal is evaluated through comprehensive simulations conducted over ns-3 5G-LENA, which demonstrate notable improvements in QoS performance and resource efficiency. In the analyzed scenarios, our proposed scheduling solution achieves a 30% reduction in radio resource utilization while maintaining full compliance with QoS requirements. These results highlight the great potential of exploiting DRL and sensing data to optimize MAC scheduling in modern wireless communication systems, offering a scalable and adaptive solution for 5G and future 6G networks.
Evaluating Fronthaul Network Performance Under the O-RAN Paradigm: A Novel Methodology Based on Queuing Theory
Fátima Khan, Óscar Gil, Luis Diez, Elena Serna Santiago, Luis M. Contreras, Ramón Agüero
IEEE Transactions on Network and Service Management, 2026
Open Radio Access Network (O-RAN) fosters a new networking paradigm that supports flexible and open architectures, while enabling the functional disaggregation of traditional, monolithic, base stations. Specifically, the Lower-Layer Split (LLS) option 7.2x divides the PHY layer into Low-PHY at Open -Radio Unit (O-RU) and High-PHY at Open -Distributed Unit (O-DU), leveraging the so-called open fronthaul network, which imposes stringent latency requirements. In this work, we introduce and thoroughly examine the time window relationships that define the latency budget allocated to the open fronthaul network. Additionally, we propose a novel methodology to analyze the delay experienced by a realistic traffic pattern over a spine-leaf topology, accounting for various O-DU locations and site pools. To address the increased traffic load introduced by the fronthaul, we present a theoretical model to characterize the average delay across different priority levels when open fronthaul traffic coexists with flows from other Radio Access Technologies (RATs). This model is then validated and broadened through ns-3 simulations. Our findings show the applicability of the proposed methodology, which could be exploited by network operators in the planning phase, evincing its suitability to obtain benchmark delay values, offering a reliable tool for performance evaluation in open fronthaul networks.
Analysis of different functional split options for XR traffic in 5G-LENA
Ana Larrañaga-Zumeta, Neco Villegas, Katerina Koutlia, Luis Diez, Ramón Agüero, Sandra Lagén
Simulation Modelling Practice and Theory, 2025
Virtualized Radio Access Networks (vRAN) allow the disaggregation of the RAN protocol stack into different network units. This disaggregation depends on the selected Functional Split (FS), ranging from Option 1 to Option 8. The possible combination of this virtualization paradigm with different FS configurations could enhance the agility, flexibility, and scalability of 5G and beyond networks. Several studies exploring FSs use open-source platforms such as srsRAN, which provide full-stack 4G and 5G RAN software. However, these platforms have limitations for large-scale network analysis and usually require hardware for realistic testing. In contrast, system-level simulators such as ns-3 5G-LENA accurately model key 5G RAN functionalities and provide a flexible, scalable, and entirely software-based environment to implement, test, and evaluate a wide range of features. Based on the above, in this work we present a software-based model for the ns-3 5G-LENA simulator that allows simulating various FS options. We study and evaluate these FS options, specifically Options 6, 7.3, 7.2, and 7.1. Moreover, we analyze their impact on the end-to-end system performance using eXtended Reality (XR) traffic and under diverse network conditions. Our analysis shows that an appropriate FS selection can improve overall performance, helping the system more effectively handle XR traffic demands across different network conditions. Specifically, when Fronthaul (FH) and bandwidth are not limiting, all FS configurations yield similar throughput and latency, with XR delays mostly below 11 ms and data rates closely matching the offered load. Under FH constraints, lower FSs (e.g., Options 6 or 7.3) are preferable due to large, bursty XR packets. Otherwise, for standardized Open RAN (O-RAN) 7.2 or 7.1 FSs, delays may exceed 50 ms and data rates degrade, significantly affecting XR traffic performance. This work provides the research community with an accessible tool for studying FSs in realistic 5G environments.

Ad Hoc Networks, 2025
Robust and efficient communication frameworks have become essential for the advancement of manufacturing and industrial processes in the era of Industry 4.0. This paper presents a comprehensive performance analysis of Eclipse Zenoh, a promising solution for the Industrial Internet of Things (IIoT). The analysis is conducted using a real testbed built with Raspberry Pi devices, comparing Eclipse Zenoh’s performance against the widely used Message Queuing Telemetry Transport (MQTT) protocol. The study assesses Eclipse Zenoh’s capabilities in terms of latency, as well as its reliability and congestion control mechanisms over various network topologies, using both Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). The results indicate that Eclipse Zenoh offers significant advantages in specific scenarios, making it a compelling choice for IIoT applications. Additionally, this paper contributes to a deeper understanding of Eclipse Zenoh’s underlying principles and its communication capabilities, positioning it as a versatile and efficient solution for modern industrial environments. • Study of Eclipse Zenoh’s underlying principles. • Latency comparative analysis of Eclipse Zenoh and MQTT. • Evaluation of Eclipse Zenoh’s reliability and congestion control mechanisms over TCP and UDP.
Security Risks in O-RAN: Vulnerabilities and Mitigation Countermeasures

Mswim 2025 27th International Conference on Modeling Analysis and Simulation of Wireless and Mobile Systems, 2025
Disaggregated and open radio access network architectures offer benefits such as enhanced interoperability, improved coordination between nodes, and cost reduction; however, they also introduce new security challenges related to open interfaces and distributed control mechanisms. This work focuses on analyzing vulnerabilities in one of the protocols used in these interfaces—SCTP—which facilitates communication with Radio Intelligent Controllers (RIC). The analysis centers on two specific attacks: denial of service and identity spoofing. Both attacks have been implemented and experimentally validated on the FlexRIC platform within the O-RAN architecture framework, contrasting with the predominantly theoretical approaches found in the literature. Based on these experiments, a critical evaluation of various security solutions proposed for SCTP is conducted. While some of these solutions offer partial mitigation capabilities, they present structural, operational, and compatibility limitations that affect their overall effectiveness. These findings underscore the need to adopt more modern and efficient transport protocols capable of natively integrating adequate security functions for O-RAN environments.
On the delay of O-RAN Fronthaul: A methodology based on Generalized Jackson Networks
Fátima Khan, Óscar Gil, Luis Diez, Elena Serna, Ramón Agüero
Proceedings IEEE Global Communications Conference Globecom, 2025
The Open-Fronthaul (O-FH) is a Time Sensitive Network (TSN) segment within the Open-RAN (O-RAN) architecture, where the legacy base station is disaggregated following the 7.2x functional split. One of the strategic objectives sought by network operators is to foster the centralization of the Open - Distributed Unit (O-DU), to serve multiple remote sites. Hence, ensuring an accurately modeling of the fronthaul performance becomes critical, due to its stringent timing requirements. In this work, we propose a novel modeling methodology, based on Generalized Jackson Networks (GJN), to derive key performance metrics such as waiting time and utilization. Additionally, we apply Kingman’s approximation to evaluate delay percentiles under high traffic load conditions. This analytical method allows for fast and scalable performance evaluation, avoiding the need for extensive packet-level simulations, which become computationally prohibitive as traffic load steadily increases. Our results evince that under sensible operating situations, the proposed approach yields rather precise results, providing an upper performance bound.
