- Design of an interference mitigation platform for roundabout vehicular ad-hoc networks: a smart signal processing and control learning approach(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2024) Ornelas Gutiérrez, Angel; Vargas Rosales, César; emimmayorquin; Zúñiga Mejía, Jaime; Zareei, Mahdi; Rodríguez Cruz, José Ramón; Escuela de Ingeniería y Ciencias; Campus Monterrey; Villalpando Hernández, RafaelaThe vehicular Ad-hoc Network (VANET) paradigm is integral to contemporary transportation systems, enabling the Internet of Vehicles (IoV) and Intelligent Transportation Systems (ITS). This research aims to deepen the knowledge of vehicular wireless communication by investigating the influence of smart signal processing and control learning strategies on interference mitigation by the Signal-to-Interference-plus-Noise Ratio (SINR) and outage performance in VANETs. Initially, the study sought to identify the best digital beamforming techniques to reduce co-channel interference and enhance communication reliability in VANET settings. Following this, it examines the incorporation of control mechanisms such as Proportional-Integral-Derivative (PID) controllers and Reinforcement Learning (RL) algorithms into VANET simulations for dynamic SINR management. Finally, the research investigates the relative efficiency of different control strategies and digital beamforming methods in reducing interference and improving communication reliability under fair conditions on a simulated roundabout VANET platform with different scenarios. Through rigorous experiments and assessments in the simulated roundabout VANET environment, the objective is to confirm the effectiveness of the suggested interference mitigation methods and offer valuable perspectives for future studies and practical implementation in real-world contexts taking advantage of the rise of cellular technologies such as 5G and 6G to advance in the development of vehicular networks with intelligent interference mitigation and SINR management framework for smart cities.
- Security automation in software defined networks(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2023-06-01) Yungaicela Naula, Noé Marcelo; YUNGAICELA NAULA, NOE MARCELO; 781291; Vargas Rosales, César; puemcuervo, emipsanchez; Zareei, Mahdi; Ramírez Velarde, Raúl Valente; Rodríguez Cruz, José Ramón; School of Engineering and Sciences; Campus Monterrey; Pérez Díaz, Jesús ArturoThe exponential increase of devices connected to the internet, and the conventional networking operation, based on distributed and static network management, have made networking an incredibly complex task. Software-Defined Networking (SDN) solves the problems arising from the static nature of conventional networking by introducing dynamism to the networking operation. SDN separates the data plane and control plane, centralizes the network control, and automates the network management. In particular, SDN technology is an effective solution to provide security to different network environments. This study solves the security problem in SDN-based networks using state-of-the-art artificial intelligent (AI) techniques. An automated security framework is proposed which integrates two components: 1) Reactive, and 2) Proactive parts. The reactive component uses Deep Learning (DL) to identify complex DDoS threats and Reinforcement Learning (RL) to mitigate them. The proactive component leverages Network Function Virtualization (NFV) to provide scalability to the proposed security framework. Extensive experiments using datasets, simulations, and physical deployments demonstrate the effectiveness of the proposed security automation framework.
