Stefano Scanzio - Theses


New Master Thesis (Research thesis, must start within **November 2021**)

Thesis about the use of Artificial Neural Networks to predict the future performance in terms of frame delivery ratio of a wireless channel based on the IEEE 802.11 (Wi-Fi) standard (see the video)

Redundancy in IEEE 802.11 networks for industrial automation (Research thesis)

Description: This thesis is about the use of wireless techniques based on IEEE 802.11 (Wi-Fi) standard (and newest ones) in order to support industrial real-time communications. Indeed, there is a strong interest in the industry in the use of wireless devices for the communication between controllers and actuator devices (e.g., industrial robots). A technique to increase transmission determinism and dependability is to transmit a duplicated frame on more than one channel. This technique, in order to improve performance, requires some modification to the IEEE 802.11g protocol. The purpose of this thesis is the modification of the models of a network simulator in order to compare different techniques based on redundancy with respect to classical models. Eventually, a prototypal implementation may be obtained using a Linux based operating system.

Required skills: Good knowledge of the C programming language, of the Linux operating system, and basic knowledge of the most important network protocols (Ethernet, IP, TCP, UDP and possibly IEEE 802.11). Not required but welcome is the knowledge of the Python language

Keywords: IEEE 802.11, Industrial Networks, Redundancy, Wi-Fi, Wireless Networks

Low-cost temperature estimation based on machine learning techniques and Raspberry Pi (Research thesis)

Description: The thesis focuses on the use of machine learning (ML) algorithms to estimate, in a low-cost way, the temperature in indoor environments. The thesis work consists of two main steps, that is the development of (1) a data acquisition system and (2) a temperature estimation system. For step (1), both PCs and Raspberry Pi devices will be employed. Raspberry Pis will be used for acquiring temperature sensor data while PCs will be employed to measure features related/influencing the temperature (e.g., the temperature measured by sensors in CPU, motherboard, hard disk, etc., as well as CPU usage, interrupts rate, etc.).
The final goal of the thesis work is to use the simple data acquired by the PCs (and the other features) to estimate room temperature through ML regression techniques especially based on artificial neural networks.

Required skills: Basic knowledge of the Linux operating system, good programming skills (especially Python programming language), basic knowledge of machine learning.

Keywords: Machine Learning, Artificial Neural Networks, Regression Techniques, Temperature Sensors, HVAC systems.

Software-defined MAC for Wi-Fi devices (Research thesis)

Description: The ability to manage Wi-Fi adapters by means of common applications executed at the user-space level is an enabling technology for many kinds of applications that require to directly manage the transmission of every single frame in the network. On the other hand, the time needed to inject the frame in the ether heavily impacts the applicability of such techniques. In this thesis, starting from the prototype implementation described in the following two references, we want to automatically estimate the time needed by the operating system to send frames on air. This thesis requires code development, analysis of methods aimed at correctly estimate this time even in disturbed environments, and experimental campaigns.

Required skills: Even if the thesis regards all the level of the Linux operating system, required skills are limited to a good knowledge of the C programming language and of the Linux operating system.

Keywords: Software-defined MAC, IEEE 802.11, message scheduling

Industrial Internet of Things based on the 6TiSCH protocol (Research thesis)

Description: Experimental thesis about next-generation Wireless Sensor Networks (WSN) based on IETF 6TiSCH, a recent emerging technology for industrial automation and robotics. The thesis work regards the use of 6TiSCH nodes for collecting big data obtained from remote sensors, as defined by the Industry 4.0 paradigm, and will be implemented using brand new OpenMote B nodes ( ) equipped with the OpenWSN operating system and/or commercial Analog Devices SmartMesh IP nodes.

Required skills: Good knowledge of the C programming language and basic knowledge of the Linux operating system.

Keywords: Industrial Internet of Things (IIoT), Wireless Sensor Networks (WSN), IETF 6TiSCH


Some examples of other possible arguments of theses are:

  • Synchronization protocols: Synchronization protocols are used to synchronize the time of different nodes in order to, for instance, perform synchronous actuations, piloted by two different nodes, at a given time. References: Paper 1, Paper 2, Paper 3 and Paper 4.
