• New IEEE Internet of Things article

  January 03, 2023: Our article "ViTaLS - A Novel Link-Layer Scheduling Framework for Tactile Internet over Wi-Fi" has been accepted for publication in IEEE Internet of Things Journal. In this work, we investigate the capability of Wi-Fi 6 and existing TI scheduling/multiplexing schemes in meeting this stringent latency constraint. Taking the concrete example of the state-of-the-art Video-Haptic multiplexer (VH-multiplexer), we highlight the pitfalls of relying on the existing Wi-Fi 6 systems for TI communication. To circumvent this, we propose Video-Tactile Latency Scheduler (ViTaLS) - a novel link layer framework for tuning the video-tactile frame transmissions to suit their heterogeneous QoS requirements.

• New IEEE Internet of Things article

  December 24, 2022: Our article "When Internet of Things meets Metaverse: Convergence of Physical and Cyber Worlds" has been accepted for publication in IEEE Internet of Things Journal. This survey introduces six typical IoT applications in the Metaverse, including collaborative healthcare, education, smart city, entertainment, real estate, and socialization. In the IoT-inspired Metaverse, we also comprehensively survey four pillar technologies that enable augmented reality (AR) and virtual reality (VR), namely, responsible artificial intelligence (AI), high-speed data communications, cost-effective mobile edge computing (MEC), and digital twins. According to the physical-world demands, we outline the current industrial efforts and seven key requirements for building the IoT-inspired Metaverse: immersion, variety, economy, civility, interactivity, authenticity, and independence.

• New IEEE Access article

  November 03, 2022: Our article "Improving IEEE 802.11ax UORA Performance: Comparison of Reinforcement Learning and Heuristic Approaches" has been accepted for publication in IEEE Access. In this paper, we address the performance of uplink orthogonal frequency division multiple random access (UORA) in IEEE 802.11ax networks. Optimization of UORA is a good case for applying ML because of its inherent complexity and dependence on situation and time-dependent parameters. In particular, we use deep reinforcement learning to tune UORA parameters.

• New Elsevier Computer Communications article

  October 24, 2022: Our article "A Location-aware RF-assisted MAC Protocol for Sectorized Vehicular Visible Light Communications" has been accepted for publication in Elsevier Computer Communications. Vehicular Visible Light Communications (V-VLC) has emerged as a viable technology complementing RF-based communication in automotive scenarios. We extensively study interference in typical vehicular scenarios. Based on the findings from this study, we propose a novel approach for medium access. We follow a location-aware cross-layer approach that exploits the Space Division Multiple Access (SDMA) feature of modern matrix lighting modules to avoid interference and thus collisions. Making use of heterogeneous communication concepts, in which vehicles share their positions via the Radio Frequency (RF) channel, V-VLC transmissions can be scheduled accordingly.

  October 21, 2022: Our article "Nanosensor Location Estimation in the Human Circulatory System using Machine Learning" has been accepted for publication in IEEE Transactions on Nanotechnology (TNANO). In this work we investigate the detection and localization capabilities of flowing nanosensors in the blood flow to report abnormalities in the human body. Specifically, we target the detection of quorum sensing molecules and provide a methodology to evaluate its performance.

• Paper Presentations at Nanocom 2022

  October 11, 2022: Jorge Torres Gomez presented our paper titled "Nanosensor Location in the Human Circulatory System based on Electric Circuit Representation of Vessels".
  Traveling through the human vessels, nanosensors are envisioned to locally detect and actuate on targets very efficiently. This paper explores the accurate modeling of the concentration level of the flowing nanosensors in vessels. We use a Markov chain formulation to predict the stationary distribution of them in the variety of vessel segments. The resulting study reveals the dynamics of the movement of nanosensors in the blood flow yielding further details on their concentration level along vessels.
