73548 - WIRELESS SENSOR NETWORKS M

Conoscenze e abilità da conseguire

This course shortly introduces to wireless communications and the main applications of WSNs; it aims at describing those wireless technologies enabling the deployment of WSNs. After a theoretical part discussing the impact of the radio environment, energy constraints and the basic elements of data aggregation techniques, laboratory activities will follow where students will use wireless devices and will realise and test the performance of WSNs in realistic environments.

Contenuti

The course is divided into three parts: 1) Theoretical part; 2) Laboratory sessions; 3) Seminars on case studies.

In the first part (approx. 25 hours) lectures will be dedicated to present the WSN protocols to be used at the different layers, which are physical, medium access control (MAC), network and application layers. Main focus will be on MAC and network layer protocols, where some guidelines for the design will be given.

In the laboratory sessions (approx. 25 hours, starting from middle Oct.) is concerned students will have possibility to program MC1322 Freescale 802.15.4-compliant devices in order to setup a real WSN. On one hand, the laboratory activities will consist in the observation of the network behavior (e.g., network formation, data transmission, etc.) and measurement of some performance metrics (e.g., throughput and delays). On the other hand, students will have the opportunity to implement their own applications and measure performance metrics when considering different parameter settings.

The third part (approx. 10 hours) seminars, dealing with some research hot topics and applications, like smart city, smart buildings and smart manufacturing, will be presented.

Prerequisites: it is requested students have knowledge of basic aspects of Telecommunications. In particular, basics concepts on spectrum analysis, modulations, thermal noise, performance of pass-band systems, basics of antennas and propagations in wireless medium.

Metodi didattici

Chalk and Talk - approx. 25 hours

Lab sessions (performed in groups of maximum 3 people) - approx. 25 hours

Problem and Enquiry sessions - approx. 10 hours

Modalità di verifica e valutazione dell'apprendimento

The exam will be composed of: 1) one open book (notes available) written part, including exercises on PHY and MAC layers (result: passed/borderline/not passed); 2) oral exam. In case the result of the written part is borderline, the oral is composed of: i) one question on the written part (PHY and MAC layers); ii) one question on the second part of the course, that is network and application layers; iii) 10 minutes presentation (with power point slides) on the laboratory activity. In case the result of the written part is passed, question i) above is skipped.

The presentation of the lab activity could be based on: i) one of the activity performed in Lab1 during the course and the related measurement results OR ii) a project invented, devised and implemented by the students. The latter project could be performed in group of maximum 3 people.

The final mark will be based on the performance achieved during the oral exam. The mark at the oral is derived as follows: starting from 30 and decreasing at each wrong reply. Laude is considered only for students presenting projects (option ii above) for the lab activity.

Studenti/sse con DSA o disabilità temporanee o permanenti: si raccomanda di contattare per tempo l’ufficio di Ateneo responsabile (https://site.unibo.it/studenti-con-disabilita-e-dsa/it): sarà sua cura proporre agli/lle studenti/sse interessati/e eventuali adattamenti, che dovranno comunque essere sottoposti, con un anticipo di 15 giorni, all’approvazione del/della docente, che ne valuterà l'opportunità anche in relazione agli obiettivi formativi dell'insegnamento.
