  3D Positioning and Posture detection using iOS

  Master Thesis

  Modern smartphones contain many sensors and frameworks that can capture the surrounding world.Capable mobile processors, machine learning and frameworks allow us to capture the pose of a human with very little extra work.

  We are looking for a student that wants to work with augmented reality and extend the posture detection system in iOS with a 3D positioning system. The software may combine multiple iPhones at different locations to enhance tracking. In the end, such a system allows to quickly create dataset necessary for WiFi sensing, create interactive games and more.

  A small introduction to the available frameworks has been given on WWDC 2020. Starting at minute 13 the video shows what is already possible today.

  Preserving Privacy against WiFi Sensing

  Master Thesis

  Your WiFi router is constantly monitoring the surrounding. You can analyze the channel state information to detect location and even trajectory of people in their homes. There are many other applications including detecting heartbeat, breathing rate, reading lips, etc. If you interested in implementing one of these systems using real hardware and finding solutions to fight against it, send me an email. Note that these are rather challenging topics as they require good knowledge of communication as well as signal processing.

  60 Ghz Channel Models: From Theory to Practice (and Back Again)

  

  Bachelor Thesis, Master Thesis

  The channel characteristics of millimeter-wave communication systems at 60 GHz differ those in lower frequency bands and require a fundamental rethinking of network design. To investigate such aspects of network performance, we developed a raytracing based simulation framework to predict the signal quality in go

  Practical Low-Layer Attacks on IEEE802.11ad by Modified WiFi Firmware

  Bachelor Thesis, Master Thesis

  Millimeter-Wave (mm-wave) communication systems such as IEEE 802.11ad use directional beams that need to be trained prior to establishing a high-throughput connection. Such beam training protocols--the backbone of mm-wave communications--have a high impacts of the security of performance. Jamming or go

  Classification and Estimation of Global Network Properties in Wireless Multi-Hop Networks

  

  Bachelor Thesis, Master Thesis

  Knowledge of global network state is crucial for several innovative network optimization techniques. However, these techniques are often evaluated in simulation environments with omniscient knowledge about the network at individual nodes, which is not realistic in practical scenarios. In fact, an individual go

  CSMA/CD for Wi-Fi

  

  Master Thesis

  Carrier Sense Multiple Access with Collision Detection (CSMA/CD) is a technique used in wired networks like Ethernet (IEEE 802.3) to improve network performance by efficient medium access. When a collision is detected, the colliding nodes terminate their transmissions to keep the collision time as short as possible. go

  Rapid Prototyping of Real-Time Wi-Fi on SDRs

  

  Bachelor Thesis, Master Thesis, Project

  Bachelor Thesis, Master Thesis

  Rapid prototyping allows to evaluate the system performance in an early stage of development under highly realistic conditions. The goal of this project is to build a real-time Wi-Fi design on the FPGA of a USRP N210 [1] software-defined radio (SDR) with Matlab/Simulink and other tools. This work should essentially serve as go

  Scheduling Algorithms in Wireless Networking Using Machine Learning

  Master Thesis

  Carrier-sense multiple access (CSMA)-type random access algorithms and their variants such as the queue-length based CSMA (Q-CSMA) [1] are widely adopted in the ad-hoc wireless networking community. Their performance with respect to various metrics, such as throughput and delay have been studied in the go
