Einzelthemen

Nr Thema Betreuer
B1 Thermoelectric energy harvesting in WSNs Dr.-Ing. Sven Pullwitt
Energy harvesting is a technique commonly used in WSNs. Many different approaches exist to collect electrical energy from ambient energy sources like light, vibrations or thermal gradients. The focus of this survey is on utilizing thermal gradients in WSNs. Your task is to summarize relevant literature and find metrics to give a comprehensive comparison of the presented approaches. Examples for the utilization of thermal gradients in WSNs can be found here:
  • Thermoelectric Energy Harvesting From Gradients in the Earth Surface
  • A Thermoelectric Energy Harvesting System for Powering Wireless Sensors in Nuclear Power Plants
B2 Trusted IoT-Sensors Lennart Almstedt
Internet-of-Things (IoT)-Sensors are used in a multitude of different use-cases, e.g., crop monitoring in agriculture. Nevertheless, in some cases, malicious actors have a motivation to alter the data reported by the sensors, e.g., a farmer has the incentive for sensor data to indicate a crop quality as high as possible. Thus, a solution is required ensuring the trustworthiness of data reported by the devices in scenarios where different stakeholders with diverging interests are present.
Your task is to present and discuss at least two solutions how data coming from IoT-sensors can be made trusted, illustrate a specific use-case for a system utilizing such sensors, and discuss the pros and cons of your presented approaches.

B3 5G NR V2X Sidelink Modes Fynn Schulze
Vehicle-to-Everything (V2X) communication is becoming ever more relevant to increase road user safety and traffic efficiency. One of several technologies that can be used by vehicles to communicate with each other is 5G, which is also known from modern smartphones. However, when vehicles communicate, not the Downlink and Uplink to the internet are relevant, but the link to their neighboring vehicles. Therefore, 5G NR V2X Sidelink can be used, which allows direct vehicle-to-vehicle communication. This also provides two modes of operation: Mode 1 requires a base station to be nearby, while Mode 2 can operate autonomously, without a base station. Your task is to explain, how these two modes operate, work out the differences between them and find out how they perform compared to each other.
  • A Tutorial on 5G NR V2X Communications
  • 3GPP NR V2X Mode 2: Overview, Models and System-Level Evaluation
  • NR Sidelink Performance Evaluation for Enhanced 5G-V2X Services
B4 eBPF's eXpress Data Path (XDP) David Niederprüm

XDP allows network traffic in a Linux system to be accessed at a very early stage on the ingress path.

Your task is to describe XDP and all of its features in detail. Also, you will conduct a comprehensive literature review on XDP and its use cases.

  • The eXpress data path: fast programmable packet processing in the operating system kernel
  • Fast Packet Processing with eBPF and XDP: Concepts, Code, Challenges, and Applications
B5 Routing in Low Earth Orbit (LEO) Satellite Networks Shashank Jhansale

Satellite networks in Low Earth Orbit (LEO), due to their proximity to Earth offer faster data transmission and reduced latency compared to traditional satellites. With the deployment of mega-constellations (e.g: SpaceX's Starlink, Amazon's Kuiper, etc.), the LEO plays a pivotal role in global communication and navigation. With a few thousand satellites in these mega-constellations, efficient routing of data is essential in order to deliver reduced latency.

Your task is to firstly provide an overview of satellite communication. Then discuss in detail at least three LEO routing strategies of your choice. Finally conclude by presenting performance of LEO in comparison with traditional satellites.

  • LEO Satellite Networking Relaunched: Survey and Current Research Challenges
  • Delay is Not an Option: Low Latency Routing in Space
  • Network Characteristics of LEO Satellite Constellations: A Starlink-Based Measurement from End Users

Ablauf

Auch in diesem Semester wird es wieder eine gegenseitige Begutachtung der Ausarbeitungen durch die Teilnehmer des Seminars geben. Das bedeutet, dass jeder Teilnehmer nach der Abgabe der finalen Version seiner Ausarbeitung zwei Ausarbeitungen anderer Teilnehmer erhält, zu denen er ein kleines Gutachten (Review) schreiben muss. Dieses Review soll sowohl positive als auch negative Kritik enthalten und dazu beitragen, dass die Ausarbeitung weiter verbessert wird. Für den Review-Prozess und die Abgaben der eigenen Arbeit wird ein entsprechendes Konferenzsystem verwendet.

Hinweise

Die Ausarbeitung ist als PDF abzuliefern. Der Umfang der Ausarbeitung muss dabei 12 bis 15 Seiten umfassen, für den Vortrag selbst sind minimal 18, maximal 22 min. angesetzt. Jeder Teilnehmer des Seminars erhält Basisliteratur zu seinem jeweiligen Thema. Darüber hinaus sollte jeder Teilnehmer zusätzlich eine selbständig Recherche, z.B. im Internet durchführen. Die Betreuer stehen hierbei jederzeit gerne hilfreich zur Seite.

Aufgrund entsprechender Erfahrungen soll auch noch auf die Selbstverständlichkeit hingewiesen werden, dass die Ausarbeitung in eigenen Worten erfolgen muss und das durch den elektronischen Bezug von Literatur verleitete Copy&Paste von Textpassagen ein Vergehen gegen die Prüfungsordnung darstellt.

Vorlagen und Hilfestellungen für LaTeX sind auf der Seite "Vorlagen für Arbeiten am IBR" zu finden. Die Verwendung von LaTeX ist verpflichtend.
