Assisted/autonomous driving is nowadays a vivid sector for both research and industry, thanks to the advances made using artificial intelligence and the pervasive and fast communication achieved by the Fifth generation (5G) of cellular networks. A fully connected environment where traveling on public roads is done with limited (or without)...
The communication services of future trains require hyperconnectivity between trains and track. Future Railway Mobile Communication System (FRMCS) reserved bands will not be able to cover all digital train requirements including passengers’ services. The 5GMED project adopts the idea where Infrastructure Managers (IMs) will collaborate with Railway Undertaking (RU) to...
Scaling network packet processing performance to meet the in-creasing speed of network ports requires software programs to carefully leverage the network devices’ hardware features. This is a complex task for network programmers, who need to learn and deal with the heterogeneity of device architectures, and re-think their software to leverage...
A significant challenge in 802.11p based vehicular ad hoc networks (VANETs) is that the cooperative awareness messages (CAMs) tend to experience collisions. In this paper, we propose an adaptive CAM messaging algorithm based on the emerging methodology of the age of information (AoI). Our objective is to minimize an age-penalty...
The introduction of the sixth generation (6G) mobile communications along with the establishment of Edge Computing and network virtualization motivate the concept of Telco Edge Platform (TEP), which is an effort towards exposing the mobile network capabilities to interested external third parties. Recently, the Operator Platform Group (OPG) has been...
The virtualization of the 5th Generation (5G) Radio Access Network (RAN), which distributes the Next Generation Node B (gNB) functions between a Central Unit (CU) and a Distributed Unit (DU), along with the emergence of slicing as a cornerstone of mobile communications networks, pose new challenges. One of these challenges...
FPGA NICs can improve packet processing performance, however, programming them is difficult, and existing solutions to enable software packet processing on FPGA either provide limited packet processing speed, or require changes to programs and to their development/deployment life cycle. We address the issue with program warping, a new technique that improves...
The introduction of AI-based smart-sensors on the network might suppose stringent requirements for the network edge, including the necessity to process real-time video feeds. Moreover, the introduction of vehicular communications allows the multiple location placement of necessary computational processes. To this end, we have proposed an AI-based smart- sensor solution...
By leveraging the use of wireless communication technologies and edge computing capabilities, Cooperative Intelligent Transport Systems (C-ITS) aims to improve safety and traffic management in mobility use cases. However, the deployment of C-ITS poses some critical challenges. Specifically, in heterogeneous systems, it is necessary to guarantee interoperability among the various...
Cooperative, Connected and Automated Mobility (CCAM) and Future Railway Mobile Communications System (FRMCS) use cases present strict requirements in terms of service end-to-end latencies, data-rates, reliability and service availability, posing challenges in the design of 5G network architectures for cross-border scenarios, where current roaming mechanisms introduce large latencies and service...
