Lectures in Italian,

Knowledge and understanding: The student must demonstrate knowledge and ability to understand advanced aspects of networking with sensor networks, from strategies at the MAC level to applications, with which to navigate the techniques of acquisition, management and analysis of sensor data in a context both theoretical and practical. Furthermore, the student must demonstrate knowledge and ability to understand advanced aspects of the systems and architectures distributed in a theoretical and practical context.
Ability to apply knowledge and understanding: The student must demonstrate the ability to use his / her acquired knowledge to solve advanced problems of networking of sensors and heterogeneous devices and their integration with other IoT technologies, from the point of view of the specific application domain, and management of systems and architectures in the IoT application context.
Making judgments: The student must be able to know how to evaluate the quality of the proposed design and implementation solutions based on different and specific service quality criteria. Furthermore, he must know how to compare the aforementioned solutions with respect to some de facto standards available in literature and open-source software.
Communication skills: The student must be able to deal with and manage all the phases of a software project focused on IoT technologies. Therefore the student must be able to produce a detailed documentation of the requirements of the application domain, of the design and implementation, exposing the results obtained and highlighting the advantages and disadvantages of the proposed solutions, also with seminar activities (possibly in English). Capacity of learning: The student must be able to update and analyze in an autonomous way specific topics and applications of the IoT and the WSNs of distributed processing systems, also by accessing databases, on-line repositories of software and development frameworks and simulations of WSN and other methods made available by the network.
For students of Machine Learning and Big Data it is necessary to have acquired the knowledge
and the skills transmitted by the following courses: Programming I, Programming II, Operating Systems, Algorithms
and Data Structures and Communication Networks.
With part I, the course introduces the issues of the emerging technology of the Internet of Things (IoT) that pervades modern everyday life, in which hundreds of thousands of heterogeneous objects they are interconnected through wireless and non-wireless communication channels to provide information and control over the physical world that surrounds us. After an overview of the main technologies enabling IoT applications, that is, wireless communication, RFID systems, Cloud Computing, the focus will be on wireless sensor networks (WSN). The WSN main characteristics, namely, the components of a sensor node, the objectives and principles of
design of a WSN architecture, the main protocols at the MAC and networking level, will be detailed.
Part II introduces systems and architectures for the IoT from the point of view of distributed systems and architectures and their planning. Firstly, the course analyses the problems underlying the distributed systems, that is, communication and definition of time and state of distribution. Then will be analysed some control algorithms used to manage distributed resources: synchronization and coordination algorithms; Deadlock; Scheduling; Leader elections; Process allocation; Termination detection; Consent; Allocation, migration and load balancing; Distributed Shared Memory. The next phase deals with the topic of distributed filesystems from the theoretical / design point of view and then from the implementation point of view,
analysing some case studies such as: NFS, ANDREW, CODA, GFS, HDFS. Finally, the course presents an introduction to the Hadoop ecosystem focusing in particular on three modules: Zookeeper, Spark, Storm. The course includes a part of the laboratory in which to experiment with the WSN OS and related WSN and with the Hadoop ecosystem.

All lectures are in pdf format, and are available through the e-learning platform of the Department of Science and Technology together with in-depth educational material (articles and extracts from reference texts, lecture notes by the lecturers).
The goal of the verification procedure is to quantify, for each student, the level of achievement of the
training objectives previously indicated. The verification procedure consists (a) of a seminar on a topic chosen by the
student and / or by teachers (20%) or, alternatively, (b) in a project proposal to be carried out in a group on an application of
interest identified by students and / or teachers (40%) through which their ability for working in a team and for preparing documents discussing their solution to the addressed problems are evaluated, and in a final oral exam ((a) 80%, (b) 60%), consisting in questions covering the whole program topics.
