Jorge Torres Gómez gave a tutorial titled "Age of Information (AoI): A Tool for Designing Time-Critical Networks" at theIEEE International Mediterranean Conference on Communications and Networking (MeditCom 2024), which was held in Madrid, Spain. The tutorial was prepared in collaboration with Nikolaos Pappas from Linköping University in Sweeden. The session introduced the role of Age of Information in designing real-time networks. The concept was revisited and various uses cases and hands-on activities were presented to optimize the network operation.

Our article Where to Decide? Centralized vs. Distributed Vehicle Assignment for Platoon Formation has been accepted for publication in IEEE Transactions on Intelligent Transactions Systems.
In this work, we explored the computation of vehicle-to-platoon assignments as an optimization problem based on similarity between vehicles.
For this, we created three approaches to solve the assignment problem: centralized solver, centralized greedy, and distributed greedy, using a Mixed Integer Programming (MIP) solver and greedy heuristics, respectively.

Our article Using Ranging for Collision-Immune IEEE 802.11 Rate Selection with Statistical Learning has been accepted for publication in Elsevier Computer Communications. We propose FTMRate, which applies statistical learning (a form of machine learning) to estimate the distance based on measurements, predicts channel quality from the distance, and selects data rates based on channel quality. We show that our approach has several positive features: it is resilient to collisions, provides near-instantaneous convergence, is compatible with commercial-off-the-shelf devices, and supports pedestrian mobility.

Our article Age of Information-based Abnormality Detection with Decay in the Human Circulatory System has been accepted for publication in IEEE Transactions on Molecular, Biological and Multi-Scale Communications. In this work, we conducted an analysis of the impact of gateway placement and infection locations on detection time, detection ratio, and the average Peak Age of Information (PAoI). Furthermore, we also added decay of nanosensors similar to operation in the human body.

Our article QL-based Adaptive Transceivers for the IoBNT Communications has been accepted for publication in IEEE Transactions on Molecular, Biological and Multi-Scale Communications. This paper introduces an adaptive transceiver scheme for bio-nano things (NTs) situated within blood vessels communicating through a time-varying molecular channel. The proposed scheme employs a Q-learning-based adaptive transceiver (a so-called QL-ADT), wherein an agent gradually learns how to adapt the transmission parameters to the current state of the channel.

Our article Synchronized Relaying in Molecular Communication: An AI-based Approach using a Mobile Testbed Setup has been accepted for publication in IEEE Transactions on Molecular, Biological and Multi-Scale Communications. In this paper, we propose using a reinforcement learning (RL)- based synchronizer to continually adapt a decoding threshold and detect transmitted synchronization frames in a dynamic molecular communication environment.

Our article Flexible Training and Uploading Strategy for Asynchronous Federated Learning in Dynamic Environments has been accepted for publication in IEEE Transactions on Mobile Computing. In this paper, we propose a flexible communication strategy for devices in asynchronous federated learning, which adapts the training and uploading actions based on the condition of the communication link. We propose a novel method of computing aggregation weight based on model distances and number of local optimizations, to control errors introduced in asynchronous aggregation while maximizing learning speed.
