DynaVLC 13 towards dynamic GTS allocation in VLC networks
Kurunathan, John Harrison; Gutiérrez Gaitán, Miguel; Sámano-Robles, Ramiro; Tovar, EduardoEnvisioned to deliver superior Quality of Service (QoS) by offering faster data rates and reduced latency in 6G communication scenarios, pioneering communication protocols like the IEEE 802.15.7 are poised to facilitate emerging application trends (e.g. metaverse). The IEEE 802.15.7 standard that supports visible light communication (VLC) provides determinism for time-critical reliable communication through its...
Machine Learning-Aided Operations and Communications of Unmanned Aerial Vehicle...
Kurunathan, John Harrison; Li, Kai; Ni, WeiOver the past decade, Unmanned Aerial Vehicles (UAVs) have provided pervasive, efficient, and cost-effective solutions for data collection and communications. Their excellent mobility, flexibility, and fast deployment enable UAVs to be extensively utilized in agriculture, medical, rescue missions, smart cities, and intelligent transportation systems. Machine learning (ML) has been increasingly demonstrating its...
Towards Safe Cooperative Autonomous Platoon systems using COTS Equipment
Kurunathan, John Harrison; Santos, José; Moreira, Duarte; Santos, Pedro MiguelThe domain of Intelligent Transportation Systems (ITS) is becoming a key candidate to enable safer and efficient mobility in IoT enabled smart cities. Several recent research in cooperative autonomous systems are conducted over simulation frameworks as real experiments are still too costly. In this paper, we present a platooning robotic test-bed platform with a 1/10 scale robotic vehicles that functions based o...
Work-In-Progress: Worst-Case Response Time of Intersection Management Protocols
Reddy, Radha; Almeida, Luis; Gutiérrez Gaitán, Miguel; Kurunathan, John Harrison; Santos, Pedro M.; Tovar, EduardoIntersections are critical elements of urban traffic management and are identified as bottlenecks prone to traffic congestion and accidents. Intelligent intersection management plays a significant role in improving traffic efficiency and safety determining, among other metrics, the waiting time that vehicles incur when crossing an intersection. This work presents a preliminary analysis of the worst-case respons...
Deep Reinforcement Learning for Persistent Cruise Control in UAV-aided Data Col...
Kurunathan, John Harrison; Li, Kai; Ni, Wei; Tovar, Eduardo; Dressler, FalkoAutonomous UAV cruising is gaining attention dueto its flexible deployment in remote sensing, surveillance, andreconnaissance. A critical challenge in data collection with theautonomous UAV is the buffer overflows at the ground sensorsand packet loss due to lossy airborne channels. Trajectoryplanning of the UAV is vital to alleviate buffer overflows as wellas channel fading. In this work, we propose a Deep Dete...
Tightening Up Security In Low Power Deterministic Networks
Tiberti, Walter; Vieira, Bruno; Kurunathan, John Harrison; Severino, Ricardo; Tovar, EduardoThe unprecedented pervasiveness of IoT systems is pushing this technology into increasingly stringent domains. Such application scenarios become even more challenging due to the demand for encompassing the interplay between safety and security. The IEEE 802.15.4 DSME MAC behavior aims at addressing such systems by providing additional deterministic, synchronous multi-channel access support. However, despite the...
WiCAR - Simulating towards the Wireless Car
Kurunathan, John Harrison; Severino, Ricardo; Tovar, EduardoDECSoS 2020 was held as part of the 39th International Conference on Computer Safety, Reliability and Security (SafeComp 2020).; Part of the Lecture Notes in Computer Science book series (LNCS, volume 12235); Advanced driving assistance systems (ADAS) pose stringent requirements to a system’s control and communications, in terms of timeliness and reliability, hence, wireless communications have not been serious...
