"Combining 5G New Radio, Wi-Fi, and LiFi for Industry 4.0: Performance Evaluation", Jorge Navarro-Ortiz, Juan J. Ramos-Munoz, Felix Delgado-Ferro, Ferran Canellas, Daniel Camps-Mur, Amin Emami, Hamid Falaki, Sensors, 24 (18), 2024. DOI: 10.3390/s24186022

Fifth-generation mobile networks (5G) are designed to support enhanced Mobile Broadband, Ultra-Reliable Low-Latency Communications, and massive Machine-Type Communications. To meet these diverse needs, 5G uses technologies like network softwarization, network slicing, and artificial intelligence. Multi-connectivity is crucial for boosting mobile device performance by using different Wireless Access Technologies (WATs) simultaneously, enhancing throughput, reducing latency, and improving reliability. This paper presents a multi-connectivity testbed from the 5G-CLARITY project for performance evaluation. MultiPath TCP (MPTCP) was employed to enable mobile devices to send data through various WATs simultaneously. A new MPTCP scheduler was developed, allowing operators to better control traffic distribution across different technologies and maximize aggregated throughput. Our proposal mitigates the impact of limitations on one path affecting others, avoiding the Head-of-Line blocking problem. Performance was tested with real equipment using 5GNR, Wi-Fi, and LiFi —complementary WATs in the 5G-CLARITY project—in both static and dynamic scenarios. The results demonstrate that the proposed scheduler can manage the traffic distribution across different WATs and achieve the combined capacities of these technologies, approximately 1.4 Gbps in our tests, outperforming the other MPTCP schedulers. Recovery times after interruptions, such as coverage loss in one technology, were also measured, with values ranging from 400 to 500 ms.

"A LoRaWAN Network Architecture with MQTT2MULTICAST", Jorge Navarro-Ortiz, Natalia Chinchilla-Romero, Felix Delgado-Ferro, Juan Jose Ramos-Munoz, Electronics, 11 (6), 2022. DOI: 10.3390/electronics11060872

In this work, an architecture for IoT networks oriented towards environmental sustainability is presented. Due to the suitability of its characteristics in terms of coverage, power and support of a large number of devices, an enhanced LoRaWAN network has been chosen as the basis for this proposal. The architecture is completed with the virtualization of the different LoRaWAN network entities and the usage of a software-defined network for their interconnection. The publication and subscription to environmental data is carried out by using the MQTT protocol. MQTT has been optimized thanks to the use of the SDN network and the use of edge computing resources, which allows multicasting of published data. Thanks to our developed MQTT2MULTICAST protocol, latency is improved by approx. 90% and the traffic load within the SDN network is reduced by 55%. An scalability analysis shows that this solution is able to support tens of thousands of LoRaWAN gateways. The proposed architecture has been implemented using commercial equipment as a proof of concept.

"Collision Avoidance Resource Allocation for LoRaWAN", Natalia Chinchilla-Romero, Jorge Navarro-Ortiz, Pablo Munoz, Pablo Ameigeiras, Sensors, 21 (4), 2021. DOI: 10.3390/s21041218

The number of connected IoT devices is significantly increasing and it is expected to reach more than two dozens of billions of IoT connections in the coming years. Low Power Wide Area Networks (LPWAN) have become very relevant for this new paradigm due to features such as large coverage and low power consumption. One of the most appealing technologies among these networks is LoRaWAN. Although it may be considered as one of the most mature LPWAN platforms, there are still open gaps such as its capacity limitations. For this reason, this work proposes a collision avoidance resource allocation algorithm named the Collision Avoidance Resource Allocation (CARA) algorithm with the objective of significantly increase system capacity. CARA leverages the multichannel structure and the orthogonality of spreading factors in LoRaWAN networks to avoid collisions among devices. Simulation results show that, assuming ideal radio link conditions, our proposal outperforms in 95.2% the capacity of a standard LoRaWAN network and increases the capacity by almost 40% assuming a realistic propagation model. In addition, it has been verified that CARA devices can coexist with LoRaWAN traditional devices, thus allowing the simultaneous transmissions of both types of devices. Moreover, a proof-of-concept has been implemented using commercial equipment in order to check the feasibility and the correct operation of our solution.

The massive deployment of Small Cells (SCs) is increasingly being adopted by mobile operators to face the exponentially growing traffic demand. Using the millimeter-wave (mmWave) band in the access and backhaul networks will be key to provide the capacity that meets such demand. However, dimensioning and planning have become complex tasks, because the capacity requirements for mmWave links can significantly vary with the SC location. In this work, we address the problem of SC planning considering the backhaul constraints, assuming that a line-of-sight (LOS) between the nodes is required to reliably support the traffic demand. Such a LOS condition reduces the set of potential site locations. Simulation results show that, under certain conditions, the proposed algorithm is effective in finding solutions and strongly efficient in computational cost when compared to exhaustive search approaches.

The Internet of Things is one of the hottest topics in communications today, with current revenues of \&\#x24;151B, around 7 billion connected devices, and an unprecedented growth expected for next years. A massive number of sensors and actuators are expected to emerge, requiring new wireless technologies that can extend their battery life and can cover large areas. LoRaWAN is one of the most outstanding technologies which fulfill these demands, attracting the attention of both academia and industry. In this paper, the design of a LoRaWAN testbed to support critical situations, such as emergency scenarios or natural disasters, is proposed. This self-healing LoRaWAN network architecture will provide resilience when part of the equipment in the core network may become faulty. This resilience is achieved by virtualizing and properly orchestrating the different network entities. Different options have been designed and implemented as real prototypes. Based on our performance evaluation, we claim that the usage of microservice orchestration with several replicas of the LoRaWAN network entities and a load balancer produces an almost seamless recovery which makes it a proper solution to recover after a system crash caused by any catastrophic event.

A lower bound of the total co-channel interference is proposed for the channel allocation problem when applied to a reduced set of nodes. The rest of the network nodes remain unaffected. This bound is independent of the particular channel allocation algorithm employed and no assumptions are made about the propagation model or the deployment scenario. Assuming that the bound is tight to the interference generated by the optimal channel allocation, its computation may help, for example, to estimate the minimum set of nodes for which channel allocation performs nearly-optimal while minimizing node reconfigurations. Another example of usage is the estimation of the minimum number of channels required for a given performance. The tightness of the proposed bound is evaluated through simulations, with a difference lower than 1\^A \% in the conducted simulations. In addition, a sample use case\^a\texteuro''adaptive local channel allocation\^a\texteuro''is also provided.

"3GPP QoS-based scheduling framework for LTE", Pablo Ameigeiras, Jorge Navarro-Ortiz, Pilar Andres-Maldonado, Juan M. Lopez-Soler, Javier Lorca, Quiliano Perez-Tarrero, Raquel Garcia-Perez, EURASIP Journal on Wireless Communications and Networking, 2016 (1), pp. 78, 2016. DOI: 10.1186/s13638-016-0565-9

This paper proposes the design of a scheduling framework for the downlink of the Long Term Evolution (LTE) system with the objective of meeting the Quality of Service (QoS) requirements as defined by the QoS architecture of the 3G Partnership Project (3GPP) specifications. We carry out a thorough review of 3GPP specifications analyzing the requirements of the 3GPP QoS architecture. LTE bearers may be associated with a Guaranteed Bit Rate (i.e., GBR bearers) or not (i.e., non-GBR bearers). Additionally, the specifications establish a Packet Delay Budget (PDB) to limit the maximum packet transfer delay. To achieve our goal, we design a channel-aware service discipline for GBR bearers which is able to fulfill not only the GBR but also the PDB. Additionally, we also design an algorithm for prioritizing GBR and non-GBR bearers from different QoS Class Identifiers (QCIs) following 3GPP QoS rules. We compare the proposed framework with two reference schedulers by means of network-level simulations. The results will show the ability of the proposed framework to address the QoS requirements from 3GPP specifications while providing an interesting performance from a spectral efficiency viewpoint.

"Removing redundant TCP functionalities in wired-cum-wireless networks with IEEE 802.11e HCCA support", Jorge Navarro-Ortiz, Pablo Ameigeiras, Juan J. Ramos-Munoz, Juan M. Lopez-Soler, International Journal of Communication Systems, 27 (11), pp. 3352-3367, 2014. DOI: https://doi.org/10.1002/dac.2546

SUMMARY The TCP was originally designed for wired networks, assuming transmission errors were negligible. Actually, any acknowledgment time-out unconditionally triggers the congestion control mechanism, even in wireless networks in which this assumption is not valid. Consequently, in wireless networks, TCP performance significantly degrades. To avoid this degradation, this paper proposes the so-called split TCP and UDP. In this approach, the access point splits the TCP connection and uses a customized and lighter transport protocol for the wireless segment. It takes advantage of the IEEE 802.11e Hybrid Coordination Function Controlled Channel Access (HCCA) mechanisms to remove redundant TCP functionalities. Specifically, the HCCA scheduler allows disabling of the congestion control in the wireless link. Similarly, the IEEE 802.11e error control service makes possible to eliminate TCP acknowledgments, therefore reducing the TCP protocol overhead. Finally, the usage of an HCCA scheduler permits providing fairness among the different data flows. The proposed split scheme is evaluated via extensive simulations. Results show that split TCP and User Datagram Protocol outperforms the analyzed TCP flavors specifically designed for wireless environments and the split TCP solution, achieving up to 95\% of end-user throughput gain. Furthermore, the proposed solution is TCP friendly because TCP flows are not degraded by the presence of flows by using this approach. Copyright 2013 John Wiley \& Sons, Ltd.

This article studies the impact on the design of scheduling algorithms for Orthogonal Frequency Division Multiple Access (OFDMA) systems of two traffic models described in the evaluation methodology proposals from standardization bodies: the full buffer and the finite buffer traffic models. The analysis concentrates on utility-based scheduling with an \^I\textpm-fair utility function for Non-Real Time (NRT) services. The results show that a gradient scheduling algorithm is able to maximize the aggregate utility over all the users when the less realistic full buffer model is adopted; but not when the finite buffer model is applied. The results also show that with the full buffer model a gradient scheduler exhibits a trade-off between average user throughput and the user throughput at 5\% outage, but it does not when the more realistic finite buffer is used. Therefore, it is concluded that designs of scheduling algorithms for NRT services for OFDMA systems carried out under the full buffer model assumption may fail to provide the desired performance benefits in realistic scenarios. Based on the results presented, a recommendation on scheduling design is provided.

ABSTRACT YouTube currently accounts for a significant percentage of the Internet's global traffic. Hence, understanding the characteristics of the YouTube traffic generation pattern can provide a significant advantage in predicting user video quality and in enhancing network design. In this paper, we present a characterisation of the traffic generated by YouTube when accessed from a regular PC. On the basis of this characterisation, a YouTube server traffic generation model is proposed, which, for example, can be easily implemented in simulation tools. The derived characterisation and model are based on experimental evaluations of traffic generated by the application layer of YouTube servers. A YouTube server commences the download with an initial burst and later throttles down the generation rate. If the available bandwidth is reduced (e.g. in the presence of network congestion), the server behaves as if the data excess that cannot be transmitted because of the reduced bandwidth were accumulated at a server's buffer, which is later drained if the bandwidth availability is recovered. As we will show, the video clip encoding rate plays a relevant role in determining the traffic generation rate, and therefore, a cumulative density function for the most viewed video clips will be presented. The proposed traffic generation model was implemented in a YouTube emulation server, and the generated synthetic traffic traces were compared with downloads from the original YouTube server. The results show that the relative error between downloads from the emulation server and the original server does not exceed 6\% for the 90\% of the considered videos.

"User-Level Quality Assessment of a Delay-Aware Packet Dropping Scheme for VoIP", Erika Patricia Alvarez-Flores, Juan Jose Ramos-Munoz, Jorge Navarro-Ortiz, Pablo Ameigeiras, Juan Manuel Lopez-Soler, Network Protocols and Algorithms, 3 (3), pp. 38-66, 2011. DOI: 10.5296/npa.v3i3.1113

To deal with congestion control in internet protocol (IP) networks, different active queue management schemes have been successfully proposed. However, many of these schemes do not take into consideration the particular Voice over Internet Protocol (VoIP) requirements, thereby potentially penalizing this traffic. In this paper, we propose and evaluate a dropping packet selection algorithm for queue management schemes. This algorithm, called Drop-SwD, protects VoIP traffic without affecting other User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) traffic. Additionally, to preserve the quality of the VoIP service, the proposed algorithm selects the lowest quality packets (with less impact on the subjective quality) to be dropped.The application of the algorithm in different active queue management schemes is evaluated using objective and subjective quality metrics and intelligibility metrics as well. As a result, we show that Drop-SwD improves the final quality of the voice packets flow, without degrading the performance of other traffic class, with respect to the packet dropping schemes of reference.

"QoE oriented cross-layer design of a resource allocation algorithm in beyond 3G systems", Pablo Ameigeiras, Juan J. Ramos-Munoz, Jorge Navarro-Ortiz, Preben Mogensen, Juan M. Lopez-Soler, Computer Communications, 33 (5), pp. 571-582, 2010. DOI: https://doi.org/10.1016/j.comcom.2009.10.016

The provision of high speed access to Internet and IP-based services is one of the main goals of beyond 3G (B3G) wireless systems. These systems will benefit from cross-layer protocol designs that will introduce interactions between different layers to obtain performance gains. The majority of the research in the field of cross-layer in B3G systems aims at improving quality of service (QoS) system centric metrics such as spectral efficiency, service latency, delay variation (jitter), etc. However, minor attention has been paid to the satisfaction of the subjective quality requirements from human users. With the goal of incorporating the subjective human perception into the cross-layer design of B3G systems, this work carries out an experimental survey of the sensitivity of the user subjective quality to the service response time for the Web browsing application. From the experimental results, a mapping from service response time and user data rate (provided by the wireless link) to mean opinion score (MOS) is derived. The presented results will show that the Web page size plays an important role in the mapping function. The derived mapping function is incorporated into a radio resource allocation algorithm for orthogonal frequency division multiple access (OFDMA) systems. This incorporation is carried out maximizing the aggregate utility over all the users in the cell. Its performance has been compared to that of the multicarrier proportional fair (MPF) under heavy load conditions with a 3G LTE simulator. The results have shown that the proposed methodology can provide an interesting enhancement of the user experienced quality compared to the MPF algorithm.

"An 802.11e HCCA scheduler with an end-to-end quality aware territory method", Jorge Navarro-Ortiz, Pablo Ameigeiras, Juan J. Ramos-Munoz, Juan M. Lopez-Soler, Computer Communications, 32 (11), pp. 1281-1297, 2009. DOI: https://doi.org/10.1016/j.comcom.2008.12.014

In this paper we present a solution for the IEEE 802.11e HCCA (Hybrid coordination function Controlled Channel Access) mechanism which aims both at supporting strict real-time traffic requirements and, simultaneously, at handling TCP applications efficiently. Our proposal combines a packet scheduler and a dynamic resource allocation algorithm. The scheduling discipline is based on the Monolithic Shaper-Scheduler, which is a modification of a General Processor Sharing (GPS) related scheduler. It supports minimum-bandwidth and delay guarantees and, at the same time, it achieves the optimal latency of all the GPS-related schedulers. In addition, our innovative resource allocation procedure, called the territory method, aims at prioritizing real time services and at improving the performance of TCP applications. For this purpose, it splits the wireless channel capacity (in terms of transmission opportunities) into different territories for the different types of traffic, taking into account the end-to-end network dynamics. In order to give support to the desired applications, we consider the following traffic classes: conversational, streaming, interactive and best-effort. The so called territories shrink or expand depending on the current quality experienced by the corresponding traffic class. We evaluated the performance of our solution through extensive simulations in a heterogeneous wired-cum-wireless scenario under different traffic conditions. Additionally, we compare our proposal to other HCCA scheduling algorithms, the HCCA reference scheduler and Fair Hybrid Coordination Function (FHCF). The results show that the combination of the MSS and the territory method obtains higher system capacity for VoIP traffic (up to 32 users) in the simulated scenario, compared to FHCF and the HCCA reference scheduler (13 users). In addition, the MSS with the territory method also improves the throughput of TCP sources (one FTP application achieves between 6.1 Mbps without VoIP traffic and 2.1 Mbps with 20 VoIP users) compared to the reference scheduler (at most 388 kbps) and FHCF (with a maximum FTP throughput of 4.8 Mbps).

"Analytic Analysis of Narrowband IoT Coverage Enhancement Approaches", P. Andres-Maldonado, P. Ameigeiras, J. Prados-Garzon, J. J. Ramos-Munoz, J. Navarro-Ortiz, J. M. Lopez-Soler, "2018 Global Internet of Things Summit (GIoTS)", pp. 1-6, 2018. DOI: 10.1109/GIOTS.2018.8534539

The introduction of Narrowband Internet of Things (NB-IoT) as a cellular (NB-IoT) technology aims to support massive Machine-Type Communications applications. These applications are characterized by massive connections from a large number of low-complexity and low-power devices. One of the goals of NB-IoT is to improve coverage extension beyond existing cellular technologies. In order to do that, NB-IoT introduces transmission repetitions and different bandwidth allocation configurations in uplink. These new transmission approaches yield many transmission options in uplink. In this paper, we propose analytical expressions that describe the influence of these new approaches in the transmission. Our analysis is based on the Shannon theorem. The transmission is studied in terms of the required Signal to Noise Ratio, bandwidth utilization, and energy per transmitted bit. Additionally, we propose an uplink link adaptation algorithm that contemplates these new transmission approaches. The conducted evaluation summarizes the influence of these approaches. Furthermore, we present the resulting uplink link adaptation from our proposed algorithm sweeping the device's coverage.

"Quality of experience based resource sharing in IEEE 802.11e HCCA", J. Navarro-Ortiz, J. M. Lopez-Soler, G. Stea, "2010 European Wireless Conference (EW)", pp. 454-461, 2010. DOI: 10.1109/EW.2010.5483493

When dealing with multiple traffic classes, it is often difficult to define a single resource sharing criterion. For instance, VoIP flows require low delay and losses, whereas FTP traffic requires high throughput. In this paper, we propose to use the Mean Opinion Score (MOS) as a unifying criterion, and to share resources so as to keep the MOS of the various flows above an acceptable threshold whenever possible. We present four different resource sharing policies: Preemptive, Non-preemptive, MOS-driven Fairness and Revenue Optimization. We analyze the different approaches through simulation, comparing their performance in terms of end-user Quality of Experience and revenue. Our results show that our scheme reacts to the changing traffic scenarios so as to achieve the pre-specified objective, thus achieving an effective exploitation of the limited bandwidth resources.

"A Traffic Management Method That Divides Time Slots into Sub-Blocks for Real Time and Non-Real Time Traffic", NOKIA CORPORATION, International Application No. PCT/FI2004/000285, Publication No. WO/2004/102899, Antti Tolli, Jorge Navarro-Ortiz, Hector Montes-Linares, 2004

A traffic management method includes the steps of dividing a time slot into sub-blocks, defining the amount of available capacity for non-real time use in a time slot, defining the number of sub-blocks reserved by real time use in a time slot, defining the number of sub-blocks reserved by non-real time use in a time slot, defining the number of free sub-blocks in a time slot on the basis of sub-blocks reserved by real time use and sub-blocks reserved by non-real time use, calculating a sub-block reservation rate for a time slot and averaging a sub-block reservation rate for a time slot to get down link sub-block reservation rate.
