Projects

Video project:

Process:

  • Select a topic (see list below) - this project is for individual students
  • Read and study the suggested paper(s) related to the topics plus any material you can find yourself
  • Prepare a 10-15 min video lecture on the topic selecting the issues that you believe are most relevant (for the video you can use slides, board, or any other instrument you believe is appropriate)
  • Upload the video on youtube as hidden link and send the link to professor indicating also the video topic in the subject 
  • Deadline: May 29
  • All students watch videos and prepare questions for students that have selected topics different from his/her own.
  • Public discussion of videos during the lecture on June 5

Evaluation:

  • up to 4 point (scale of 30 points for MRN only) based on video quality and public discussion

Topics:

  • SDN/NFV
  • Cloudification of RAN
  • Edge Computing in mobile networks
  • Network Slicing
  • Massive MIMO

Data analysis project:

Project Description:

Cellular operators work to recognize under-performing network layers or elements, with the aim of maximizing the efficiency of their networks. To fulfill this goal, cellular operators usually undertake detailed analysis on heterogeneous types of on-field collected network data, coming from different sources such as end users devices, base station counters, network probes, etc. Moreover, the collection of on-field measurements over large time periods (months or years) is crucial to recognize trends happening in the network.

In this project, we are interested in assessing the impact of the lock-down due to COVID-19 pandemic onto the network of a big Italian cellular operator. Exploiting the availability of network data relatively to the periods Before and During the lock-down, we are interested in investigating:

The variation of base stations traffic load, in terms of number of connections and downloaded data volumes,

The variation of RRC Setup and Re-Establishment Success Rates.

This analysis aims at understanding i) whether it is possible to differentiate (and recognize) residential and non-residential network areas, ii) whether the increase of residential connections and consequently the raising of connection hot-spots have lowered network performance, iii) possible action plans to improve network efficiency in serving connection hotspots.

Rules:

  • Participating to the project require signing a Non Disclosure Agreement (NDA)
  • Individual participation or participation in teams of two students is allowed
  • All teams will be assigned the same project and are expected to work independently

Process:

  • Send an email with the name(s) and email(s) of team member(s) to prof. Capone.
  • Get the data set and work on it focusing on one or more of the objective (be creative)
  • Prepare a presentation of the work and send it to prof. Capone
  • Deadline: June 4
