Short Description: Development and implementation in Excel/VBA of visible light communication (VLC) techno-economic tool for IoT services.
Future IoT will need wireless links with high data rates, low latency and reliable connectivity despite the limited radio spectrum. Connected lighting is an interesting infrastructure for IoT services because it enables visible light communication (VLC), i.e. a wireless communication using unlicensed light spectrum. This work will aim at developing a tool to perform an economic evaluation of the proposed solution in the particular case of a smart office.
For that purpose, the following tasks will have to be performed:
Definition of a high-level framework specifying the different modules that will be implemented as well as the required inputs and the expected outputs of the tool.
Development of a cost evaluation Excel-VBA tool. This tool will allow to evaluate different variations of the selected case study and if possible, to compare different alternative models (e.g., dimensioning) or scenarios (e.g., building types).
Short Description: Develop, implement and evaluate two solutions to detect and identify failures in flexible optical networks.
yle="text-align: justify;">Flexible optical networks achieve a significant increase of network capacity by assigning as much spectrum to the demands as needed. With advances in transponders supporting software tunable channel configurations, network planners are able to select the best combination of data rate, modulation format and forward error correction (FEC) for each light-path. However, the impact of failures in these networks is higher due to the closeness between channels as well as the low OSNR margins.
yle="text-align: justify;">Hence, in this thesis we will look into the monitoring capabilities of flexible optical networks provided by existing components as well as extra monitoring equipment. All the gathered monitoring information should be processed by machine learning based classification tools such that fast and efficient failure diagnosis can be achieved.
Impact of noise-aware routing on different multiplexing techniques in flexible optical networks
Keywords: optical networks, RSA
Short Description: Implementation and evaluation of different multiplexing techniques
Optical core networks deploy fixed grid in order to accommodate their demands. The trend is however, migrate towards flexgrid networks able to use as much spectrum as required by the demand allowing a better use of the spectrum. However, the Routing and Wavelength Assignment (RWA) paradigm becomes more complex as it has to find the suitable spectrum of the demand.
This thesis will consider different multiplexing alternatives: space division, band division multiplexing, etc.
The objective is to compare the performance, throughput, BoM, etc. of the different alternatives for different networks and demand evolution matrices.
