Preserving Privacy against WiFi Sensing
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

Evaluating Bluetooth as a Link Layer Technology for Energy-Constrained Ad hoc Networks
Master Thesis, Bachelor Thesis
Bluetooth allows direct device-to-device communication, for instance, between smartphones. Especially BT Low Energy was conceived to be very energy-efficient. This is why vendors allow Bluetooth background operation which is crucial for Disruption-Tolerant Networks (DTNs) as smartphones act as data mules and 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

Coordinated Millimeter-Wave Beam-Steering for Dense Network Deployments
Bachelor Thesis, Master Thesis
Beam-steering is the backbone of millimeter-wave (mm-wave) networks and key to achieve data-rates of multiple gigabit per second. Nodes must steer their antennas so that they maximize the signal gain towards the intended communication partner. In large networks with dense deployments, nodes should also 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
