73548 - Wireless Sensor Networks M

Learning outcomes

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.

Course contents

The course is divided into three parts: i) theoretical part; ii) laboratory activities; iii) seminars on case studies.

In the first part lectures will be dedicated to present the WSN protocols to be used at the different layers, which are physical, medium access control, network and application layers. Some cross-layer topics, such as energy efficiency, time synchronisation and distributed detection, will be also addressed.

As far as the laboratory activity is concerned students will have possibility to program MC1322 Freescale 802.15.4-compliant devices in order to setup a real WSN. Form one hand, the laboratory activities will consist in the observation of the network behavior (network formation, multi-hopping data transmission, etc.) through the use of a sniffer; from the other hand, students will have the opportunity to implement their own applications, program devices and perform some measurements.

The third part of the course will be dedicated to a sequence of seminars, dealing with some research hot topics and applications, like smart city, smart buildings, smart body.

Assessment methods

“On line” Mode. This is for students following the course and coming to the exam before end of February 2017. The exam will be composed of: 1) one intermediate test including 2 exercises to be performed in class; 2) one homework (design of a WSN), assigned at the end of the course, to be performed at home and to be delivered one week before the oral exam; 3) oral exam. The oral is divided into two parts: i) discussion of the homework (point 2 above) and one question on the theoretical part of the couse; ii) 10 minutes presentation (with power point slides) on the laboratory activities.

“Off line” Mode. This is for students not following the course or that will not give the exam by end of February. The oral is divided into three parts: 1) one exercise; i) two questions related to the theoretical part of the course; ii) 10 minutes presentation (with power point slides) on the laboratory activities.

Teaching tools

Laboratory: Freescale 802.15.4-compliant devices, sniffers, PCs.

Theoretical part tools: Slides, books, scientific papers.
