Einzelthemen

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 CopyPaste 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.

Nr Thema BetreuerIn
B1 Coexistence of ITS-G5 and C-V2X Fynn Schulze

When it comes to vehicular communication, there are currently two competing technologies. IEEE 802.11-based communication (called ITS-G5 in Europe) and celluar-based communication (often called C-V2X). These two technologies are based on different concepts and are therefore not interoperable. Your task will be to present the differences of ITS-G5 and C-V2X and explain the problems that arise from coexistence. Furthermore, you will have to compare different strategies to solve these problems.

  • A Tutorial on 5G NR V2X Communications
  • Enabling Efficient Coexistence of DSRC and C-V2X in Vehicular Networks
  • Performance evaluation for co-channel coexistence between ITS-G5 and LTE-V2X
B2 Security and Privacy for Wireless Ad-Hoc Sensor Networks Leonard Zurek

Many low power wireless sensor networks are prone to various attacks (e.g. path injection in routing protocols) due to their ad-hoc architecture. With advances in hardware and support for acceleration of cryptographic calculations as well as memory management units, new approaches towards securing these networks emerged.

Your task consists of an extensive literature research on the development of security mechanisms for ad-hoc low-power networks similar to standards implemented in industrial networks. Afterwards you will have to compare your findings, put them in context and present the challenges and missing links for them.

Literature starting points:

  • Security and Privacy Threats for Bluetooth Low Energy in IoT and Wearable Devices: A Comprehensive Survey
  • Security of RPL Based 6LoWPAN Networks in the Internet of Things: A Review
  • μDTNSec: a security layer with lightweight certificates for Disruption-Tolerant Networks on microcontrollers
  • Security and Privacy in Vehicular Ad Hoc Network and Vehicle Cloud Computing: A Survey

B3 Comparison of Mechanisms for Roaming in Wifi Networks David Niederprüm

In large Wifi networks with multiple access points (AP), mobile clients must establish a new connection to another AP when getting out of range of their current AP. This process is called roaming (or sometimes handover).

Your task is to describe the existing mechanisms for Wifi roaming from IEEE 802.11 standards and from recent literature. Providing a complete overview of Wifi roaming is of higher importance than describing every detail of a single mechanism.
You shall compare the performance of different roaming mechanisms with each other.

  • IEEE 802.11{r,k,v}
  • Continuous multi-access communication for high-resolution low-latency V2X sensor streaming
B4 On the versatile applications of SDN Torben Petersen

The increasing size and complexity of modern networks lead to one major problem: the administration of the routers and switches that make up the network. While configuring a small number of such devices may be manageable, configuring a large number may lead to inconsistent or error-prone configurations. Software-defined networking (SDN) aims to solve this issue by configuring these devices via a central controller, reducing the administrative overhead and risk of misconfiguration.

Since SDNs conception, multiple publications have been released presenting SDN-based systems. Each of these systems leverages SDN to solve a specific issue. Your task is to explain the concept of SDN and compare these different systems with each other. This requires that you explain the problems the system intends to solve and discuss how SDN is used to solve them.

  • Software-Defined Networking: The New Norm for Networks
  • Dynamic application-aware resource management using Software-Defined Networking: Implementation prospects and challenges
  • Centralized QoS Routing Using Network Calculus for SDN-Based Streaming Media Networks
  • An SDN Perspective on Multi-Connectivity and Seamless Flow Migration
