Prerequisites
The course is self-contained and therefore there are no specific pre-requisites.
Objectives and Contextualisation
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, energy and water distribution, 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, so a higher level of abstraction is required at the interface level (APIs and Middleware) and virtualization (computing and communications).
Goals:
Establish the fundamentals of the internet of things (IOT): device, periphery (edge) and cloud (cloud); together with the user interfaces.
Learn to classify embedded processors, sensors, actuators, and systems, and select communications protocols and cloud options
Evaluate the functional requirements and the performance in terms of cost, real time comnditio and energy efficiency
Evaluate the cost of data structures based on sensors, computing, communication, storage and visualization 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
- Communicate efficiently, orally or in writing, knowledge, results and skills, both in the professional environment and before non-expert audiences.

Activities and Methodology
| Title | Hours | ECTS | Learning Outcomes |
|---|---|---|---|
| Type: Directed | |||
| Lessons and Seminars | 30 | 1.2 | 2, 1, 3, 5, 7, 8, 9 |
| Type: Supervised | |||
| Laboratories & Design Project | 28 | 1.12 | 1, 3, 7, 9 |
| Type: Autonomous | |||
| Study & Homework | 90 | 3.6 | 2, 1, 3, 4, 6, 7, 8, 9 |
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.
Attendance will be mandatory for the Design of the IoT project and Laboratory sessions that will be done in groups of 2 or 3 people.
The laboratory sessions will use a supervised format (not guided) to offer greater autonomy to students and a more personalized support.
This course will use UAB's virtual campus at https://cv.uab.cat.
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
Continous Assessment Activities
| Title | Weighting | Hours | ECTS | Learning Outcomes |
|---|---|---|---|---|
| Evaluation of activities developed in tutored sessions (laboratories) | 40% | 0 | 0 | 1, 3, 7 |
| Individual activities (i.e. exercices) | 20% | 0 | 0 | 2, 1, 3, 5, 7, 8, 9 |
| Report and defence of the design project | 40% | 2 | 0.08 | 2, 1, 3, 4, 6, 5, 7, 8, 9 |
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 final grade 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 be reported 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 is necessary 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 activities will be proposed along the course for groups of lectures.
Type B activities, will require delivering partial reports of a global IoT project document every 2 weeks.
Type C activities, will require delivering two partial reports (one by mid semester and a 2nd one at the end).
To obtain MH it will be necessary that the students have an overall qualification higher than 9 with the limitations of the UAB (1MH/20students). As a reference criterion, they will be assigned in descending order.
A final weighted average mark not lower than 50% is sufficient to pass the course, provided that a score over one third of the range is attained in every one of the Marks for items B and C. If not reached, the mark will be 4.0.
Plagiarism will not be tolerated. All students involved in a plagiarism activity will be failed automatically. 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 the corresponding reports.
An student not having achieved a sufficient final weighted average mark, may opt to apply for remedial activities (individual work or additional synthesis examination) the subject under 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 not attendance 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 corresponding comments. Students can make complaints about the grade of the activity, which will be evaluated by the teaching staff responsible for the subject.
Repeating students will be able to “save” their grade in laboratory activity.
