By providing storage and computational resources at the network edge, which enables hosting applications closer to mobile users, Multi-Access Edge Computing (MEC) uses backhaul, core more efficiently, thereby reducing overall latency. Fostering synergy between 5G MEC brings ultra-reliable low-latency in data transmission, paves way towards numerous latency-sensitive automotive use cases, with ultimate goal of enabling autonomous driving. Despite benefits significant latency reduction,...
With the advance of Internet Things (IoT), interaction between humans and smart objects is already a reality. New applications that are expected to operate in dynamic environments must support different modes human/machine (e.g., voice sign language), exhibit same or better performance heterogeneous wireless optical networks, be able react real time. In particular, dispersed computing has arisen as an approach deal with latency issues this context. work described herein, we design lighting...
Cellular technologies are widely used in the ICT domain, that paving way towards new opportunities for education and practical experimentation. It also tackles software-related engineering areas, from Digital Processing (DSP) to Software Defined Networks Network Virtualization applications. Due various constraints such as limited access hardware components, high costs of equipment, spectrum regulations must not be violated, telecommunications, electrical engineering, electronics usually...
5G has opened up possibilities of introducing new use cases and business models that could not be perceived before. In the context public safety, offers immense opportunities towards enhancing mission success situation awareness during emergency management. This paper introduces Back-Situation Awareness (BSA) application enabling early warning/notification to vehicles an approaching vehicle indicating its presence time it will arrive. Such is expected give drivers enough create a safety...
Cooperative Intelligent Transportation Systems (CITS) deploy the Awareness Basic Service to exchange Messages (CAMs) among road C-ITS entities, e.g., vehicles and roadside units (RSUs). CAMs support vehicular safety traffic efficiency applications that require continuous status information of surrounding entities. These messages provide awareness in Non-Line Sight (NLOS) vehicle are an essential feature guarantee vehicles. Typically, display depend on specific hardware software, which...
A comunicação Dispositivo-a-Dispositivo (D2D) é um dos mecanismos para a desoneração das redes 4G, via offloading de dados outras redes. Redes híbridas D2D/4G possuem como desafio multiplexação eficiente interfaces comunicação, o que pode impactar diretamente na Qualidade Experiência (QoE) usuários. Este trabalho apresenta QD4G, uma plataforma emprega Aprendizado Máquina controlar quando clientes usando padrão DASH (Dynamic Adaptative Streaming over HTTP) devem empregar rede 4G ou D2D. O...
Quality of Experience (QoE) should be the driver for network orchestration in 4G networks. At same time, must able to cope with high bandwidth requirements from applications such as video streaming, while dealing a large number users. This paper proposes orchestrator that adjusts parameters improve QoE streaming. The uses Device-to-Device (D2D) communication user's QoE, also reducing demand on network. use D2D is triggered by machine learning engine. Experiments made physical testbed show an...
Vehicle to Everything (V2X) systems are starting be used in some regions worldwide; consequently, this leads the consolidation of its major components, putting into practice all potential V2X. The Smart Highway testbed located Antwerp, Belgium, makes available V2X for experimentation and evaluation, providing flexible support different access technologies simultaneously. Namely, ITS-G5 short-range communication Cellular (C-V2X) short- long-range communication. applications needed explore,...
In this demonstration, we explore the impact of optical-wireless network infrastructure when vary locus computing for Internet Things (IoT) services. Those services could involve devices ranging from low complexity sensors and actuators (e.g., smart light bulbs) to more advanced ones multimedia glasses); in our experiment, focus on former. We design a system that allows control bulbs (on/off, color, brightness) through voice sign language. location at which command processing (voice or...
It is estimated that Internet traffic will triple in five years, which increase server response time. One way to reduce such time balance the load on replicated servers using SDN switches. However, existing switches have performance limitations influence of balacing. This work compares balancing policies: round robin, random, txbytes (transmitted bytes), cpuq-load (CPU usage and number open connections), load/load-prev (load forecast with switch statistics). These policies consider as cost...
The benefits of Cooperative Intelligent Transport Systems (C-ITS) span a range areas, such as road safety and service reliability. Thus, traffic accidents can be avoided, ultimately human lives saved. As C- ITS disseminate in-vehicle information, an error in the disseminated velocity accuracy may cause accidents, particularly automated autonomous driving contexts. Hence, it is vital to detect these errors warn vehicles about inaccuracy speed reported by vehicle Awareness Message (CAM). To...
In this paper we demonstrate a framework to support research on Cooperative Awareness Messages (CAMs) through monitoring dashboard, deploying portable environment named CAM Application Framework (CAMAF); it manages the received CAMs and updates corresponding specific monitor for each active Intelligent Transportation System (C-ITS) entity. Each is configurable by choosing fields making or changing algorithms display desired information. We have tested our proposal in C-ITS testbed with real...
