Proposal of Theses
The thesis activity foresees the introduction of the student in a stimulating team where 5 PhD students collaborate to perform research in the field of cellular systems and satellite networks (LTE, WiFi, WiMAX, DVB-S2/-RCS2). The duration of the thesis may last from 6 to 9 months. There is also the possibility to combine the thesis activity with fellowship grants or international mobility fellowships. The theses are carried out in the framework of project activities, like the following EU projects: WiNeMo and SatNEx III.

The current thesis topics are described below ("laurea magistrale" degree); if interested, please send an email to receive more details or book an appointment.

Cognitive cellular networks with algorithms based on game theory

Cognitive wireless networks will permit to utilize the frequency spectrum in a more efficient way for 4G systems, like LTE. The basic concept is that 4G operators will have permanently allocated portions of the spectrum, while other parts will be available on demand, depending on congestion conditions by means of a competitive mechanism. The scope of this thesis is to study novel algorithms for the allocation on demand of portions of spectrum by using schemes based on the game theory and using simulations in the ns-3 environment.

Multipath-TCP and cell offloading techniques in WiFi-LTE systems

Mobile 4G networks can exploit the cooperation with local wireless networks (WiFi) towards which 4G users can be readdressed when the 4G access network is congested. The aim of this thesis is to study and evaluate the performance of cell offloading algorithms that take different aspects into account, such as traffic load conditions and transmission (PHY) conditions. In the ns-3 environment, multi-homing protocols (such as Multi-Path-TCP) will be considered to allow the mobile terminal to exploit simultaneously the capacity available with WiFi and LTE.

Network coding for applications to Terabit satellite systems

Future-generation satellite networks will make use of the bandwidths at high-frequencies (Q/V/W) in order to increment the available capacity up to Terabits per second. Q/V/W bands are however heavily affected by atmospheric phenomena (rain) that significantly reduce the availability of the satellite link. The aim  of this thesis activity is the study and the implementation in the ns-3 environment of handover algorithms based on network coding techniques in order to improve the availability of future Terabits per second satellite systems. The study of the handover time intervals will be carried out in Matlab.
