abstract = {\"{U}nmanned Aerial Vehicles (UAVs) have developed substantially in various 

practical use cases and require reliable wireless connections. 

Cellular-connected UAVs will benefit from ultra-reliable and low-latency 

communication (URLLC) in 5G and beyond networks. Their integration with 

Time-Sensitive Networking (TSN) via campus solutions can provide swarm 

robotics wireless links with deterministic behavior, flexibility, and 

coverage. Reliable yet cost-effective and flexible evaluation of the 

integration is still challenging for academia and industry. We focus on 

open-source testbeds due to their maturity and transparency in verifying 

evaluation results. Subsequently, we systematically survey and categorize 

testbeds in the literature that use commercial-off-the-shelf hardware. Our 

study outlines options for building a full-fledged testbed for integrating 

TSN with 5G and beyond for research and development. This study initiates 

one of the first steps toward facilitating future research."},

abstract = {The industry is striving to deploy private cellular networks in their 

factories. 

The envisioned use cases, such as industrial automation, require 

Ultra-Reliable and Low-Latency Communications (URLLC). 

In 5G, the User Plane Function (UPF) handles user traffic and hence 

significantly influences the performance in terms of latency and 

throughput. 

However, present UPFs are often user-space applications running on 

commercial off-the-shelf (COTS) servers introducing computational delays 

that follow long-tailed distributions. 

In this work, we compare modern packet processing acceleration technologies 

such as XDP, DPDK, and P4 and their respective tail-latency performance. 

Our results demonstrate the clear advantage of hardware-based P4 

implementations in terms of reduced tail-latency of about 6 μs at a 

percentile of 99.999% for small packets. 

Furthermore, we also demonstrate that software-based frameworks can compete 

with hardware-based approaches. 

For example, DPDK achieves tail-latencies of approximately 23 μs at a 

percentile of 99.999%. 

Based on our findings, we illustrate the trade-offs between low-cost 

software- and high-performant hardware-based packet processing systems.},

In this work, we conduct packet-based active measurements to evaluate the performance of a state-of-the-art 5G standalone system in a production environment. The focus is on whether 5G connections can meet the requirements specified by 3GPP in terms of delay and reliability. The results indicate that without cross-traffic, the requirement of a delay of less than 10 ms for 99.9 % of the packets can be met for the remote control and fleet management of mobile robots. However, as soon as cross-traffic is injected, especially in the uplink, the upper percentiles of the delay increase significantly, thus failing to hold the reliability requirements.},

their realization is a challenging task. Time-Sensitive Networking (TSN) is 

intended to enable deterministic communication over inexpensive Ethernet 

networks. Standardized by the IEEE TSN working group, TSN enables precise 

control of time synchronization, traffic shaping, reliability enhancements, 

and network administration to answer the demands of industrial control 

applications. Subsequently, there is a significant need to enable turnkey 

research and 

implementation efforts. However, a current lack of open-sourced testbed 

implementations to investigate and study the behavior of TSN network 

devices limits verification to simulation and theoretical models. We 

introduce a publicly available, flexible, and open-sourced measurement 

testbed for evaluating TSN in the context of industrial automation 

applications to address the need to perform real-world measurements. In 

this contribution, we describe our testbed combining 

Commercial-Off-The-Shelf (COTS) hardware and existing open-source tools as 

a platform for in-depth evaluation of TSN devices. Providing detailed TSN 

backgrounds, we describe an in-depth performance analysis for our 

implementation. For a common Tactile Internet scenario, we observe an 

accuracy of close to 5 ns achievable with our publicly available COTS 

setup.},

abstract = {Delivering content from a network via a client-server architecture is 

expensive not only for content owners but also for network operators. 

Moving content closer to the end user is already used in Content Delivery 

Networks (CDN). Mobile Edge Cloud (MEC) enables us to shift the content 

even closer by using the storage of end users. But, due to the large media 

files, storage and transport costs for peers increase significantly. 

Network Coding can reduce these costs. However, peers in CDNs tend to be 

highly fluctuating and often need to be restored, making continuous 

availability of data at the network edge a problem. While for uncoded data, 

individual packets lost due to peer failures can be tracked to determine 

availability, the availability of coded data is currently distinguished 

only in two cases: either there are still enough linearly independent 

packets to decode the file, or there are not. However, we have found that 

the network's combined coded cache loses quality over time due to recovery. 

This quality loss, which we refer to as grade, can be measured by very 

cost-effective monitoring. If the grade falls below a certain limit, we can 

intervene in the network by performing a cache refresh to prevent data 

becoming unavailable preemptively. In this paper, we present the cases in 

which such monitoring is useful, how the grade is calculated, and when a 

cache refresh is necessary. The results show that we can reduce network 

traffic by up to 34 % with minimal storage costs through efficient 

monitoring.},

flexible deployment, can be a promising candidate for production 

plants to complement existing Wifi-based networks. Toward 

that goal, 5G has to satisfy strict requirements about real-time 

communication to facility novel use cases. However, the realtime- 

capability of 5G is not well understood yet. In this work, we 

deliver insights into the functioning of 5G NR RAN Release 

15, which includes actual one-way delay and Round-Trip Time 

(RTT) measurements for Downlink and Uplink in a private 5G 

Standalone campus network. The extensive measurement results 

reveal that these delays are correlated, and the corresponding 

RTT, i.e. the sum of Downlink and Uplink delays, is discreetly 

clustered, ranging between 12ms and 40ms. The measurements 

also show that the distribution of RTTs is mainly dependent on 

the packet rates and their inter-arrival times. Our study helps 

expand the current understanding of 5G used for latency-critical 

applications. We make the code and the measurement data traces 

publicly available as the IEEE DataPort 5G Campus Networks:

functional optical transceivers are still rare. This work introduces the design and implementation of a tunable transceiver and an 

optical communication network on top of an external laser source, functioning in the near-Infrared (IR) range. The transceiver 

is composed of the integrated circuit of an optical chip, a hardware acceleration interface, and a customized Digital-toAnalog Converter (DAC) at the transmitter and receiver side. The 

photonic chip was designed and fabricated on CMOS compatible and represents an integrated Optical Phased Array (OPA), 

which modulates light for multi-channel beam control. The twodimensional beam steering relies on an array of waveguide 

grating couplers, which ensures high accuracy and directionality during the narrow beam radiation. In the longitudinal direction, 

the beam is steered by a wavelength tuning mechanism, while for the lateral direction, the lobe is controlled by a network of 

thermo-optical phase shifters. The hardware accelerator, a Multiprocessor System-on-Chip (MPSoC), computes the source data 

with random coefficient in Galois Fields (GF) to generate coded packets, which flow throughout the optical beams. Additionally, 

the accelerator is also responsible for the selection of the input voltage within the DACs to control the optical chip. To ensure 

successful packet transmission when the transmitter and receiver are in motion, a dynamic sliding window protocol based on 

Random Linear Network Coding (RLNC) was designed and implemented at the MAC layer. Extensive simulation demonstrates 

that our implementation results in an average packet success rate of 93.58 % with reduction in average delay.},

abstract = {\"{A}pplying renewable energy in smart micro grid (MG) is increasingly receiving attention to reducing greenhouse gas emissions. However, the mismatch between supply and demand hinders the realization of this process. With the widespread use of Electrical Vehicles (EVs) and the development of emerging Mobile Edge Clouds (MECs), intelligent energy optimization becomes a way to the addressee the challenge. Therefore, in this paper, we propose a novel two-stage approach based on Deep Learning (DL) to reduce overall energy cost for sharing EVs integrated MG by forecasting its state and optimizing EVs scheduling. Our simulation results show that the joint design of forecasting and optimization reduces the overall energy consumption and the payment to the external grid."},

abstract = {Digital Twin (DT) implementations can reduce latency drastically in future communication systems for steering and control of cyber-physical systems (CPS). When the CPS and its DT periodically exchange information to repair possible desynchronisations between the two systems, this can lead to large data traffic flooding the networks. This work proposes a goal-oriented communication approach based on message identification (ID), which only sends repair data when necessary, but adds control traffic and a probability of not repairing some desynchronisations between the two systems. We compare optimal ID codes and a hash function for detection whether desynchronisation correction is necessary. Our method can reduce the traffic to within 0.3 % of its optimal value while repairing 99.97 % of all desynchronisations for 4 kbit of data and grows even better for larger data.},

abstract = {Network monitoring is an important task in future networks to mitigate outages, guarantee low latency and high throughput, and quickly adapt to changes of network conditions. Software-Defined Networking (SDN) enables dynamic adaptation to changing network environments through the ability to program network behavior. However, to react properly to changing environments, precise and credible information about performance metrics such as latency is necessary. Recent research activities exploited OpenFlow, an SDN protocol, to measure delays inside the network, without the need for additional hard- or software. In this paper, we propose an improved method to measure one-way delays, which can handle asymmetrical delays between the SDN controller and the switches. We implemented our approach in a hardware testbed to evaluate it in a setup with asymmetrical delays and traffic loads. The results show that we are able to measure asymmetrical delays in the network. Additionally, the proposed solution is capable of discovering the network topology and therefore gives together with the performance metrics the information for efficient routing decisions. In addition, we make the source code of our implementation publicly available.},

functions of mobile robots, such as navigation, are computationally 

expensive. When deployed at the robot, those functions demand high energy

Edge Cloud (EC) can significantly reduce the robot's computing demand and 

resources, subsequently reducing energy consumption. We offload 

intelligence of mobile robot control functionality, i.e., navigation, 

localization, and control to an EC. The EC processes sensor data and sends 

the robot the directional velocities. Meanwhile, a 5G wireless connection 

ensures the necessary low latencies and high throughputs. We demonstrate 

the feasibility of offloading SLAM and navigation in an EC based on a use 

case in automotive production. Additionally, we developed a digital twin of 

the robot and visualized its current sensor data.},

abstract = {In recent years, robots are taking on more and more tasks throughout many different application domains. Many of those robots work fully automatically and without human intervention. However, more complex tasks still require to be done by a human in remote control. One example would be robot remote surgery. Remote controlling a robot requires ultra-low latency on the communication, to allow fast and precise movements. To make this possible with today's systems, the human operator must be in the same room. Enabling the operator to operate from anywhere around the world, would bring a huge benefit as travels for highly trained experts can be minimized. In order to allow wider distances between the operator and robot, we propose an AI-based prediction. Predicting the robots behavior can generate negative latency, which improves the precision of control. In large-scale communication networks, the main part of experienced latency comes from the propagation delay and is therefore not avoidable. Predicting upcoming data before it actually arrives, can create a zero-latency experience for the human operator. To prove this idea in the context of remote robot control, we propose JAVRIS. Using the CMIYC demonstrator as example, JAVRIS improved the score of an inexperienced user by over 1000%.},
