Integrating Citizens’ Avatars in Urban Digital Twins.
García-Luque, Rafael; Toro-Gálvez, Lorenzo; Moreno, Nathalie; Troya-Castilla, Javier; Canal-Velasco, José Carlos; Pimentel-Sánchez, Ernesto[et al.] (River Publishers, 2023-12-23)
Urban Digital Twins (UDT) represent a powerful tool to effectively make cities smart. Generally, UDTs are linked with other Digital Twins to build ecosystems where the citizen is at the heart of the ecosystem. This is why ... -
Intelligent OLSR Routing Protocol Optimization for VANETs.
Recent advances in wireless technologies have given rise to the emergence of vehicular ad hoc networks (VANETs). In such networks, the limited coverage of WiFi and the high mobility of the nodes generate frequent topology ... -
Key-Value vs Graph-based data lakes for realizing Digital Twin systems
Pérez Porras, Daniel; Muñoz Ariza, Paula; Vallecillo-Moreno, Antonio Jesús; Troya-Castilla, Javier (2022-07-05)
Digital twins constitute virtual representations of physically existing systems, synchronized at a specified frequency and fidelity. One way to connect physical and digital twins is through data lakes, which are efficient ... -
Light commodity devices for building vehicular ad hoc networks: An experimental study.
Toutouh-el-Alamin, Jamal; Alba-Torres, Enrique (Elsevier, 2015-10-13)
Vehicular communication networks represent both an opportunity and a challenge for providing smart mobility services by using a hybrid solution that relies on cellular connectivity and short range communications. The ... -
Location-aware scalable service composition.
Pozas García, Nicolás; Durán-Muñoz, Francisco Javier; Moreno Berrocal, Katia; Pimentel-Sánchez, Ernesto (Wiley, 2023)
The problem of service composition is the process of assigning resources to services from a pool of available ones in the shortest possible time so that the overall quality of service is maximized. This article provides ... -
Managing Reputation in Collaborative Social Computing Applications
Moreno, Nathalie; Perez-Vereda, Alejandro; Vallecillo-Moreno, Antonio Jesús (AITO, 2022-06)
Reputation is a fundamental concept for making decisions about service providers. However, managing reputation in peer-to-peer distributed applications is not easy due to the lack of a central server that can compute this ... -
Model Transformation Testing and Debugging: A Survey
Model transformations are the key technique in Model-Driven Engineering (MDE) to manipulate and construct models. As a consequence, the correctness of software systems built with MDE approaches relies mainly on the correctness ... -
Modeling Urban Digital Twins over the Cloud-to-Thing Continuum
The interest in the development of smart cities and the proliferation of digital twins as a powerful information processing technology have lead to the definition of Urban Digital Twins (UDTs). UDTs model city aspects such ... -
