Prerequisites

The course is self-contained and therefore there are no specific pre-requisites.

This year, we will add (i) EdgeAI as essential element of the IoT value chain; (ii) better understanding of the energy budget along the Chain; (iii) a more application-oriented approach and (iv) new development platforms.

(this subject is given together with the Internet of Things subject of the Bachelor's Degree in Computer Engineering)

Objectives

Description:


The ICT world is being structured on various concepts. One of them is the Internet of Things, which is based on expanding the computing domain to connected objects (devices) of small size and energy consumption that interact with the real world via sensors and actuators in different areas: personal / wearables, health, home automation, environment, security & safety, distribution of utilities (energy, water, gas), automotive, etc. These connect through various protocols to a fixed or mobile intermediate platform (edge) that manages, filters and processes part of the data locally. In turn, it is connected to the cloud where the data is stored, processed and displayed. The implementation of these systems requires integrating the various concepts, acquired in previous courses, in this new device-edge-cloud paradigm associated with different types of computing platforms (single-, multi-, many-core processors) with different requirements of functionality, power, latency, bandwidth and cost; different programming and communication models; and different cloud options for back-end and (front-end for the user interface), so a higher level of abstraction is required at the interface level (APIs and Middleware) and virtualization (computing and communications). All this with the everyday more important need to apply AI at different levels of the chain.


Goals:

Establish the fundamentals of the internet of things (IOT): device, periphery (edge) and cloud (cloud); together with the user interfaces and artificial intelligence.

Learn to classify and select processors, sensors, actuators, and systems, and select communications protocols.

Evaluate the functional requirements and the performance in terms of cost, real time condition and energy efficiency.

Develop data structures for sensors, computing, communication, storage and visualization and evaluate its cost at each level.

Select embedded and mobile platforms for the edge and cloud solutions for back-end and front-end.

Manage the virtualization of computing and communications

Design a theoretical and practical example case of the entire IoT chain for a specific application

Learning outcomes

  1. Work cooperatively in complex and uncertain environments and with limited resources in a multidisciplinary context, assuming and respecting the role of the different members of the group.
  2. Design the most efficient data acquisition system for a system to support autonomous driving.

Learning activities and methodology

Title Hours ECTS Learning outcomes
Personal study & work 90 3.6
Project Design & Laboratory (prototyping) 28 1.12 1, 2
Theoretical background & Seminars 30 1.2

The learning methodology will combine: master classes, activities in tutored sessions, project based-learning and use cases, debates and other collaborative activities; and laboratory sessions.

There are three ways to choose a project:

  • By agreement among the group members. In the initial phases, a brainstorming session with the professors will be encouraged, from which students must choose the one they find most viable.
  • Choosing from challenge proposals offered by the professors.
  • Choosing from challenge proposals proposed by external entities. Currently, we have proposals from the Molins de Rei Town Council, channeled through the UAB Research Park (PRUAB). To participate in these proposals, in addition to the course activities, it will be necessary to complete 6-8 hours of entrepreneurship training at the PRUAB and present the work at the Molins Town Council in a public event on December 11, 2026. In return, students will receive 3 elective credits and can win a prize.

Attendance will be mandatory for the Design of the IoT project and Laboratory sessions, which will be organized on the same multidisciplinary groups of 2 or 3 people from the different degrees that take the subject.

The laboratory sessions will use a supervised format (not guided) to offer greater autonomy to students and a more personalized support.

Any lack of attendance must be communicated in advance to the teacher in charge, attaching the corresponding reasonable justified reasons.

This course will use UAB's virtual campus at https://cv.uab.cat.

The use of AI is allowed in this course and it is recommended to validate its result before submitting any report since it can make serious errors that may imply negative evaluations. Students will have to report which AI tools did they use and were.

Note: 15 minutes of a class will be reserved within the calendar established by the centre or by the degree for students to answer the surveys to evaluate the performance of the teaching staff and the evaluation of the subject or module.

Annotation: within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment

Continuous assessment activities

Title Weight Hours ECTS Learning outcomes
Evaluation of activities developed in tutorized sessions (laboratories) 40% 0 0 1, 2
Report and defence of the design project 40% 2 0.08 1, 2
Individual activities (e.g. exercices) 20% 0 0 1, 2

This course does not provide for the single assessment system (No exam).

The evaluation of the course will follow the rules of the continuous evaluation and the finalgrade for the course, is calculated in the following way:

A - 20% from the mark obtained by the student through the evaluation of activities (i.e.exercises). When an evaluation activity is scheduled, the evaluation indicators will bereported and its weight in this qualification.

B - 40% from the mark obtained through the evaluation of the IoT design project.

C - 40% from the mark obtained by the student of the laboratory work and reports. It isnecessary to exceed 5 (out of 10) in this item to pass the subject.

All activities will require delivering report through the virtual campus.

Type A individual activities will be proposed along the course for groups of lectures.

Type B group activities, will require delivering partial reports of a global IoT project documentevery 2 weeks.

Type C group activities, will require delivering two partial reports (one by mid semester and a 2ndone at the end).

To obtain MH it will be necessary that the students have an overall qualification higher than9 with the limitations of the UAB (1MH/20students). As a reference criterion, they will beassigned in descending order.

A final weighted average mark not lower than 50% is sufficient to pass the course, providedthat a score over one third of the range is attained in every one of the Marks for items Band C. If not reached, the mark will be 4.0.

Plagiarism will not be tolerated. All students involved in a plagiarism activity will be failedautomatically. A final mark no higher than 30% will be assigned.

Open source code or available libraries can be used but they must be referred in thecorresponding reports.

An student not having achieved a sufficient final weighted average mark, may opt to applyfor remedial activities (individual work or additional synthesis examination) the subjectunder the following conditions:

- the student must have participated in the laboratory activities and design project, and

- the student must have a final weighted average higher than 30%, and

- the student must not have failed any activity due to plagiarism.

The student will receive a grade of \"Not Evaluable\" if:

- the student has not been able to be evaluated in the laboratory activities due to notattendance or not deliver the corresponding reports without justified cause.

- the student has not carried out a minimum of 50% of the activities proposed.

- the student has not done the design project.

For each assessment activity, the student or the group will be given the correspondingcomments. Students can make complaints about the grade of the activity, which will beevaluated by the teaching staff responsible for the subject.

Repeating students will be able to “save” their grade in laboratory activity.

Note: Given that this subject belongs to a non-linguistic degree, enrolled students have the right to request an additional academic recognition of 1.5 ECTS credits once they have passed the subject. These credits will be added to the transcript as an elective subject (with a grade of "Pass"), always respecting the UAB's maximum regulatory limit of 12 total credits for language proficiency (6 credits in the case of double degree students). For more information regarding deadlines and the associated fee, please contact Academic Management directly.
