 In this thesis, the task is to develop and evaluate an approach to optimize the availability  of medical applications, i.e., modular application functions (MAFs), when executed in the network. For that, suitable real use cases are identified together with our partners at MITI (Hospital "Rechts der Isar"). The optimizing approach then leads to a specified distribution of the processing and networking resources, satisfying the minimum needs of critical applications while considering the needed availability.

 

 The result will be an evaluated placement approach for applications in the medical environment considering the availability.

Processing Priorization of MAF Chains in the Medical Context

Beschreibung

 

In future communication systems such as 6G, in-network computing will play a crucial role. In particular, processing units within the network enable to run applications such as digital twins close to the end user, leading to lower latencies and overall better performance. However, these processing resources are usually shared among many applications, which potentially leads to worse performance in terms of execution time, throughput, etc. . This is especially critical for applications such as autonomous driving, telemedicine or smart operations. Hence, the processing of more critical applications must be prioritized.

 

 In this thesis, the task is to develop and evaluate a priorization approach for chains  of modular medical applications, i.e., modular application functions (MAFs). Hereby, this work extends an already existing work, focusing on the placement of only single MAFs with prioritization. In this work, suitable real use cases are identified together with our partners at MITI (Hospital "Rechts der Isar"). The priorization approach then leads to a specified distribution of the processing and networking resources, satisfying the minimum needs of critical applications.

 

 The result will be an evaluated priorization approach for applications in the medical environment.

Detailed Requirement Analysis for the Reliability and Availability of Medical Network Communication

Beschreibung

 

6G soll als neuer und zukünftiger Mobilfunkstandard den Menschen in den Fokus rücken. Neben sehr geringen Latenzen und extrem großen Datenübertragungsraten wird das Netzwerk zuverlässiger, sicherer und dynamischer. Diese Eigenschaften sind besonders in der Medizin und der Medizingerätetechnik gefragt, um intelligente Datenübertragung zwischen Geräten und Menschen zu ermöglichen. Im Rahmen des Verbundprojektes „6G-life“ sollen zwei medizinische Demonstratoren entwickelt werden, die diese Netzwerkeigenschaften untersuchen. Ein Demonstrator ist ein robotisches Telediagnostiksystem zur Remote Untersuchung von Patienten. Ein zweiter Demonstrator beschäftigt sich mit der raumadaptiven Erfassung von Vitalparametern.

Ziel der Forschungspraxis ist die Ermittlung von medizintechnischen Anforderungen an die Netzwerkkommunikation hinsichtlich der Ausfallsicherheit. Dies beinhaltet eine Recherche gängiger Normen und Richtlinien, die bei der medizinischen Datenübertragung berücksichtigt werden müssen, sowie Maßnahmen, die zur Sicherstellung zuverlässiger Kommunikation getroffen werden können. Darüber hinaus sind Interviews mit Medizinern wünschenswert, um die Nutzerseite zu berücksichtigen.

 

Im Rahmen der Arbeit sollen folgende Punkte behandelt werden:

  • Recherche zu gängigen Richtlinien und Mechanismen, die in der medizintechnischen Netzwerkkommunikation zur Ausfallsicherheit eingesetzt werden.
  • Interviews mit Klinikpersonal
  • Evtl. Messung mit den vorhandenen Testbeds

 

Diese FP wird in Kooperation mit unseren Partnern der MITI Gruppe am Krankenhaus "Rechts der Isar" durchgeführt.

 

Voraussetzungen

  • Motivation
  • Interesse an Medizintechnik
  • Deutsch (zwingend erforderlich zwecks der Interviews)
  • Grundlegende Kenntnisse über Netzwerkkonzepte

Dynamic Security Analysis in 5G RAN

Stichworte:
5G, SDR, Security, RAN

Beschreibung

 

The mobile security sector has uncovered numerous vulnerabilities within link and session-establishment protocols. These vulnerabilities can be exploited using software-defined radios (SDRs) to interfere with, impersonate, or flood layer-3 (L3) messages, compromising security and privacy. These risks persist even within the latest 5G mobile network standard. With affordable SDRs and open-source cellular software stacks readily accessible, the economic and technical obstacles to practical cellular attacks are relatively minimal. In this work, we would like to investigate the resource depletion and Denial-of-Service (DoS) attacks, that are well known in LTE [1], within 5G RAN. The main focus will be regarding the RRC and NAS protocol vulnerabilities that are mentioned in [1]. The expected results would be to recreate these attacks experimentally in our 5G RAN with srsRAN [2]. If time allows, further tests can be performed over campus network with commercial 5G RAN.

Implementation of a Medical Communication Protocol

Beschreibung

The next generation of communication networks, namely 6G, will enable a huge variety of medical applications. In the current phase, our research focuses on optimizing the interaction between network and medical application developing. For this, we joined forces with the Minimally Invasive Interdisciplinary Therapeutical Intervention (MITI) group, sitting at the hospital "Rechts der Isar".

This research internship focuses on one certain use case, the mobile patient monitoring of patiens in the operation room. In particular, the vital parameters of the patient are continously measured and sent to a server. The task of the research internship is to develop and implement the communication protocol between the sensors and the processing server. Hereby, a basic implementation is already given. However, key components are still missing, which should be implemented and evaluated within the scope of this research internship.

 

Please note, that the real setup is located at MITI. You may have to work there.

Further Development and Implementation of a System for Room Sensitive Measurement of Vital Parameters

Beschreibung

As a new and future mobile communications standard, 6G is intended to focus on people. In addition to very low latencies and high data transmission rates, the network will be more reliable, secure and dynamic. These features are particularly in demand in medicine and medical device technology to develop intelligent value-added functions for patients and clinical staff. As part of the BMBF-funded joint project "6G-life", a demonstrator will be developed that uses and requires these network properties to enable new intelligent assistance functions.

 

The aim of this research practice is the further development of a system for the environment-aware measurement of vital parameters. For this purpose, a detailed literature research on the possibilities of biosignal processing and data transmission protocols in the medical field will be conducted. Subsequently, an already existing measurement setup is to be further developed, which records vital parameters by means of suitable sensors (ECG, temperature, SpO2, blood pressure, ...). A message architecture is to be designed that allows secure and controllable transmission of the sensor data to computing units located in the network for biosignal processing. The results of the signal processing are to be displayed on an already existing GUI.

 

This Research Internship is in cooperation with the MITI research group. Most work may be done at their site.

Working Student for the Medical Testbed

Beschreibung

Future medical applications put stringent requirements on the underlying communication networks in terms of highest availability, maximal throughput, minimal latency, etc. Thus, in the context of the 6G-life project, new networking concepts and solutions are being developed.

For the research of using 6G for medical applications, the communication and the medical side have joined forces: While researchers from the MITI group (Minimally invasive Interdisciplinary Therapeutical Intervention), located at the hospital "Rechts der Isar", focus on the requirements of the medical applications and collecting needed parameters of patients, it is the task of the researchers at LKN to optimize the network in order to satisfy the applications' demands. The goal of this joint research work is to have working testbeds for two medical testbeds located in the hospital to demonstrate the impact and benefits of future 6G networks and concepts for medical applications.

Your task during this work is to implement the communcation network for those testbeds. Based on an existing open-access 5G network implementation, you will implement changes according to the progress of the current research. The results of your work, working 6G medical testbeds, will enable researchers to validate their approaches with real-world measurements and allow to demonstrate future 6G concepts to research, industry and politics.

In this project, you will gain a deep insight into how communication networks, especially the Radio Access Network (RAN), work and how different aspects are implemented. Additionally, you will understand the current limitations and weaknesses as well as concepts for improvement. Also, you will get some insights into medical topics if interested. As in such a broad topic there are many open research questions, you additionally have the possibility to also write your thesis or complete an internship.

 

Voraussetzungen

Most important:

  • Motivation and willingness to learn unknown things.
  • Ability to work with various partners (teamwork ability).

 

Of advantage:

  • C/C++ and knowledge about how other programming languages work (Python, etc.)
  • Knowledge about communication networks (exspecially the RAN), 5G concepts, the P4 language, SDN, Linux.
  • Initiative to bring in own ideas and solutions.

Please note: It is not necessary to know about every topic aforementioned, much more it is important to be willing to read oneself in.
