Obiettivi dell'insegnamento

The goal of the course is to teach students the methodologies for modelling, analyzing, and designing wireless networks. Moreover, the course provides the students the instruments for understanding of the modern standard technologies related to Mobile Radio Networks and Wireless Internet. Each topic related to modelling methodologies is treated both theoretically and practically. Selected topics related to technologies are associated with some experimental activities.

  • Polling systems (waiting time models, exhaustive service, gated service, limited service, round robin service)
  • Scheduled radio access (signalling needs, channel state dependent scheduling, multi-carrier scheduling).
  1. Ad hoc networks
  • Routing in ad-hoc networks (proactive routing, reactive routing, geographic routing, hybrid routing).

Prerequisiti

Students are required to know the principles of networking and communications systems. They are also expected to have a basic knowledge of traffic models and optimization.


Modalità di valutazione

The assessment will be based on a written exam at the end of the course and on additional experimental/project activities.

The written exam is based on numerical exercises (2-3) and open questions (2-3) on the network analysis and dimensioning models. The written exam can assign up to 28 points. The student can select one of the additional experimental/project activities proposed in the course and get assigned up to 5 additional points. 30 cum laude will be assigned when the total score is greater or equal 31.
