Title:Non-Terrestrial Networks in Beyond 5G: Revolutionizing Connectivity Through Satellite Integration
|
Affiliation:Ruhr University Bochum, Germany
|
Abstract: The rapid evolution of satellite technology is transforming Non-Terrestrial Networks (NTN) into a cornerstone of beyond 5G mobile systems. Historically part of GSM, satellite connectivity has now matured to the point where users can connect directly via satellites using standard mobile devices, eliminating the need for large, specialized terminals. Satellite constellations are expected to not only act as backbone networks but are also becoming integral as 6G radio access nodes, offering global coverage and serving as cloud platforms capable of hosting applications directly on satellites. This talk will explore recent developments in NTN, showcasing existing products, ongoing standardization efforts, and the vast research challenges that remain. From seamless connectivity to the deployment of mobile applications in space, NTNs are set to play a critical role in shaping the future of mobile communications.

|
Affiliation:Western University, Canada

Abstract: Today's advanced and
intelligent cyber-physical systems (CPS) offer immense potential to enhance our technologically driven
society with a multitude of benefits and conveniences. However, deploying these smart CPSs, such as
autonomous transportation, virtual healthcare, smart agriculture, and smart-city applications, requires
guaranteed network performance, which is particularly challenging in rural, remote, and other areas
where traditional high-speed terrestrial networks (TN) are limited or unavailable. In this talk, Dr. Haque
will explore how non-terrestrial networks (NTN), such as Low Earth Orbit (LEO) satellites, Free-Space
Optical (FSO) communication, and UAV networks, can play a transformative role by integrating with
traditional high-speed terrestrial networks to establish global connectivity, ensuring that these real-time,
robust, mission-critical smart systems and digital services are reliably available anytime, anywhere,
allowing rural and remote populations to benefit from the same advancements as urban centers.
Dr. Haque will also highlight the research challenges and open questions that drive innovation in this
rapidly evolving field, shaping the future of our globally connected smart world. Additionally, Dr. Haque

Title:Lessons Learned from Implementation of a Satellite Router
|
Affiliation:Belgrade University, Serbia
|
Abstract: LEO (Low Earth Orbiting)
satellite networks open up new opportunities for alternative Internet backbones. They can readily cover
remote rural areas and the areas affected by natural and social disasters. Advanced link layers were
developed for LEO systems providing rates of 10Gbps between satellites and ground and rates of 100Gbps
for intersatellite communication. Fast link technologies impose high-capacity switching and routing on
satellites.
FPGA (Field Programmable Gate Array) chips are appropriate for implementation of satellite switching
and routing due to their programmability. Electronics on satellites is susceptible to single and multiple
event upsets (SEU and MEU) that are caused by critical radiation effects. FPGA chips can be
reprogrammed remotely using wirless connection to a satellite when certain circuits are affected by
radiation. Various protection mechanisms that include redundancy can be incorporated on the FPGA
design.
We designed and implemented a complete router on the FPGA chip comprising 10Gbps and 100Gbps
ports that would be suitable for LEO satellite network [1]. Our goal was to evaluate scalability of a satellite
router using the high-end FPGA chips at the time. We implemented all basic switching and routing
functionalities: packet processing, IP lookup, packet segmentation and reassembly, buffer management,
scheduling of cells, and cell forwarding through a cross-bar matrix. Control plane was implemented using
the Quagga open-source suite, and it was integrated with the data plane. At the end, the implemented
sattelite router was thoroughly tested, and capabilities of the implemented data plane was evaluated
using our developed testing platform based on DPDK (Data Plane Development Kit).
Design of the implemented satellite router was determined by the architecture of Xilinx Ultrascale+
FPGA chips. Inputs and outputs with 100Gbps bit-rates where split into 10Gbps channels that could
feed the on-chip memory blocks. For this reason, packets could arrive to the output buffers out of
order, so, the design added mechanisms for packet reordering in the output buffers. Packet segmentation,
reassembly and reordering at 100Gbps speed were the most complex functionalites of the implemented
router prototype.
Scalability of the design was analyzed according to the resource utilization of the router prototype. The
number of ports, and therefore the router capacity, was limited by the available Xilinx development board
that allowed two 100Gbps ports and eight 10Gbps ports. Intermediate memory blocks had highest
utilization close to 50%, and, consequently, they are anticipated to be the main bottleneck. These blocks
are mostly used by 10Gbps ports for implementation of IP lookup. It can be concluded that IP lookup
should be avoided in satellite backbone networks. For example, IP lookup can be replaced by MPLS
lookup at the expense of more complex control plane. In this way, scalability of the satellite router could
be improved as the control plane is not resource intensive.

Title:Space-Air-Ground Integrated Systems (SAGIN) - Architecture, Operations, and Algorithms
|
Affiliation:Budapest University of Technology and Economics, Hungary
|
Abstract: The talk presents a novel framework of temporal graph modeling for data routing in non-Terrestrial Networks (NTNs), which is envisioned a critical part of 6G mobile systems. To handle its highly dynamic nature of network topology and nodal interconnection due to the high mobility of these non-terrestrial equipment such as low-earth orbbit (LEO) satellite and high-altitude platform (HAP), the previous art significantly relies on time-expanded graphs (TEG) at the expense of poor scalability. Without using TEGs, our proposed framework treats the capacity between each NTN node pair and available buffer size of each NTN node as time-varying functions, and these time-varying functions are employed in a novel routing algorithm that is a modified version of the maximum flow search algorithm in which a suite of novel mathematical operations and operands is defined. The talk will discuss the experiment results via computer simulation that verifies the proposed framework and compares it with the TEG based methods.

Title:Empowering Semantic Satellite Communications with Generative AI
|
Affiliation:University of Electro-Communications, Japan
|
Abstract: As data demand continues to
grow, traditional satellite communications are increasingly constrained by limited spectrum resources
and cannot meet the requirements for high volume data transmissions. This talk introduces a semantic
communication approach based on generative AI for large volume image data transmissions, offering a
revolutionary solution that reduces bandwidth requirements by transmitting semantic information rather
than every bit. Generative AI dynamically generates the required content based on received semantic
information and user needs, allowing the system to flexibly respond to different user demands and
provide highly personalized services. This approach optimizes bandwidth utilization, reduces latency,
and lays the foundation for efficient and reliable satellite communications with broad application
prospects.
