Experimental tools are a key factor in both academic and industrial research communities to create design evaluations of new networking technologies that involve troubleshooting or changing the planning of deployed networks. Physical Software-Defined Radio (SDR) experimental platforms enable a design solution for the quick prototyping of wireless communication systems. However, SDR-based experimental platforms incur high costs, which leads to scalability limitations in the experimental settings. Having said this, network simulators, emulators, and new testbeds have attracted increasing attention. Emulation-based research prototyping can be distinguished from real communication networks and SDR-based platforms by allowing a tradeoff between cost and flexibility. This paper examines the Mininet-RAN emulation tool, which, as well as Radio Access Network (RAN) modeling, provides a way to test Open RAN Intelligent Controller (RIC) services without the need to deploy an entire RAN infrastructure. The Mininet-RAN creates virtual network elements, such as hosts, L2/L3 devices, controllers, and links, by combining some of the best emulator features, hardware testbeds, and simulators. By running the current code of standard practice Unix/Linux network applications and network stack, the Mininet-RAN enables real-world network data traffic patterns to be delivered to the RIC, regarding the most significant aspect of the dynamic generation of wireless system's KPIs. We provide the basic code of Mininet-RAN for the first two O-RAN Alliance-defined use cases involving V2X and UAV. The xApps are being implemented in O-RAN SC near-RT RIC, with Mininet-RAN which provides a closed-loop validation environment.
This work aimed to develop a real-time test platform for systems associated with the tactile internet area. The proposal comprises a master device, a communication channel and a slave device. The master device is a tactile glove (wearable technology) that works as a tactile interface based on vibratory feedback. The master device can interact with virtual elements (local or remote). The Matlab/Simulink environment and a robotics toolbox form the communication channel and the slave device. The communication channel introduces a bidirectional connection of variable latency, and the slave device is defined as a robotic phantom omni manipulator emulated in Matlab/Simulink. The virtual robotic manipulator, the slave device, can generate different types of tactile sensations in the tactile glove, that is, in the master device. The platform can model tactile sensations such as coarse roughness, fine roughness, smoothness, dripping and softness. The proposed platform presented adequate results and can be used to test various algorithms and methods correlated to the tactile internet.
This work aimed to develop a test platform, in real-time, for tactile internet applications. The platform is formed by a master device called here master device (MD), a channel, and a slave device called here slave device (SD). MD is a tactile glove based on vibratory feedback, responsible for making interaction with virtual or remote objects possible. A software platform models the communication channel and SD in the Matlab-Simulink environment. The channel simulates a low latency connection, and the SD is characterized by a Phantom Omnitype robotic manipulator, which is simulated through the Matlab-Simulink environment. Tactile sensations of coarse roughness, fine roughness, smoothness, dripping, and smoothness were developed and modeled. The platform presented very satisfactory results in which it can be used to simulate various scenarios, algorithms, and devices associated with the tactile internet. Resumo: Esse trabalho teve como objetivo o desenvolvimento de uma plataforma de teste, em tempo real, para aplicações em internet tátil. A plataforma é formada por um dispositivo mestre chamado aqui de master device (MD), um canal e um dispositivo escravo chamado aqui de slave device (SD). O MD é uma luva tátil baseada em feedback vibratório, responsável por tornar possível a interação com objetos virtuais ou remotos. Já o canal de comunicação e o SD são modelados por uma plataforma de software no ambiente Matlab-Simulink. O canal simula uma conexão de baixa latência e o SD é caracterizado por um manipulador robótico do tipo Phantom Omni no qual é simulado através do ambiente Matlab-Simulink. Foram desenvolvidas e modeladas sensações táteis de rugosidade grossa, rugosidade fina, lisura, gotejamento e suavidade. A plataforma apresentou resultados bastante satisfatórios no qual poderá ser utilizada para simular vários cenários, algoritmos e dispositivos associados a internet tátil.
