Abstract

Extended Reality (XR) technology is proposed as a key enabler for the development of immersive applications, thus transforming the way users interact within digital environments. In communication networks, XR will be able to introduce immersive network functions with the potential to enhance the network experience. This paper proposes a comprehensive architectural framework designed to support the deployment of XR Functions (XRFs) within a Digital Twin Network (DTN) environment in order to provide immersive functions of any type, including control and management functions, that are not available in the original network. The proposal can be deployed in relevant fields where digital twins are promising, such as medical applications, surveillance systems, autonomous driving and space communications. The proposed architecture must consider the need for minimal hardware and software resources, along with a network topological configuration with the objective of providing a robust yet lightweight framework, allowing devices with limited computing power, such as smartphones and laptops, to benefit from the enhanced network functionalities provided in the Digital Twin Network, without affecting the original network (ON).

Abstract

Intelligent Transport Systems (ITS) are fundamental to reaching the concept of smart cities. However, the incoming development of vehicular applications will originate an increase in long-term evolution (LTE) traffic demand, so an approach consists of reducing the cell coverage area. This paper presents an alternative solution to deal with areas with a lack of coverage originated by the deployment of LTE micro-cells.We propose a heterogeneous network algorithm named Multi-Metric Heterogeneous Network Algorithm(MMHNA), which uses LTE and dedicated short-range communications (DSRC) technologies. The objective is to extend the LTE communication range with the support of DSRC technology through a forwarding process. This proposal will allow vehicles to send messages to a server directly connected to the evolved Node B (eNB), i.e., the radio network node for LTE networks, even if the sending vehicle is out of range of the eNB. This work was supported by the Spanish Government under research projects “sMArt Grid using Open Source intelligence (MAGOS)" TEC2017-84197-C4-3-R and “Enhancing Communication Protocols with Machine Learning while Protecting Sensitive Data (COMPROMISE)" (PID2020-113795RB-C31/AEI/10.13039/501100011033). Xavier Calle Heredia and Pablo Barbecho Bautista are recipient of a full scholarship from the Secretaria Nacional de Educación Superior, Ciencia y Tecnología (SENESCYT).

Abstract

This research work analyzes the urban transportation system, which is one of the problems attempted to solve by means of digital cities. A system is designed through the use of a wireless sensor network (WSN) where each unit has a ZigBee communication module and a global positioning system (GPS). This allows to obtain the position and speed of each transport unit and to transmit that information to the central station, where a software is developed to analyze and monitor the obtained information through a server and a database
