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 Data collection using Data MULEs Lennart Almstedt
Data MULEs are mobile entities able to collect data from sensor networks. In this regard, data MULEs might be the only way to route data to a sink, e.g. in remote areas, or they might make routing data to a sink more efficient by requiring less hops.
Your task is to firstly present different use-cases for data MULEs in sensor networks. Using those use-cases, different problems arising with the use of data MULEs should be summarized and explained, with focus on the security of data and on the incentivization for participants acting as data MULE.
  • Data MULEs: modeling and analysis of a three-tier architecture for sparse sensor networks
  • InDaMul: Incentivized Data Mules for Opportunistic Networking Through Smart Contracts and Decentralized Systems
B3 An overview on the challenges of computation on energy harvesting systems Torben Petersen

One of the bottlenecks for wireless sensor networks (WSN) is the power supply of it's nodes. While batteries may seem like the obvious solution, they will run out of energy eventually and must be replaced, which hinders long term operation. In order to allow node operation without much maintanence, a class of nodes have emerged which harvest their energy from the environment (e.g. by using solar cells). But these have their own drawbacks, since the environment energy is harvested from may not be static, but dynamic. This dynamic behavior may result in phases of energy drought (e.g. during night when using solar cells) during which the node has to be supplied out of stored energy. But since these storages are often limited in size and they may not always be filled to their full capacity, the node will run out of energy, shuts down and resumes it's operation once enough energy as been harvested.

This intermittent behaviour of a nodes power supply results in the operation of the nodes beeing quite different when compared to regular computers. Your task will be to present the main challenges of running programs on these intermittently powered devices and discuss publications that aim to solve them.

  • Intermittent Computing: Challenges and Opportunities
  • Hibernus: Sustaining Computation During Intermittent Supply for Energy-Harvesting Systems
  • Reliable Timekeeping for Intermittent Computing
B4 URLLC and 5G: Enabling Smart Factories Shashank Jhansale
The Ultra Reliable Low Latency Communication (URLLC) is essential for many modern applications ranging from smart factories to Augmented Reality/Virtual Reality (AR/VR) gadgets. 5G is one of the primary communication technology which supports the advancement of these applications. Your task is to firstly provide a brief overview of URLLC in the context of smart factories. Then, with a use case describe the key enabling technologies of 5G supporting industrial automation use cases.
  • Ultrareliable and Low-Latency Wireless Communication: Tail, Risk, and Scale
  • URLLC and eMBB in 5G Industrial IoT: A Survey
  • 3GPP TS 22.104 - Service requirements for cyber-physical control applications in vertical domains

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.
