Detailed Contents (Spanish)

This subject addresses knowledge related to data networks when they are created without using fixed physical infrastructures. In this case they are known as ad-hoc networks.

The architectures and signaling protocols associated with this type of networks will be studied.

The practices are focused on the study of the protocols of this type of networks and to implement networks of this category.

We work with news that provides students with the ability to stay up-to-date on science and technology developments, especially in this type of subject that are so linked to a dynamic environment such as telecommunications, and specifically Telematics Engineering.

Theory
Lesson 1. Introduction to ad-hoc networks.
There will be an introduction to ad-hoc wireless networks as well as the basic terms commonly used in these environments (MANET, Mobile Adhoc Network).

Lesson 2. Fundamentals of Ad-hoc Networks.
Here we will briefly recall concepts, technologies, techniques, protocols and systems studied in other subjects of the degree that are used by ad-hoc networks. Some of these constitute operating principles of the ad-hoc networks.

Lesson 3. Ad-hoc network protocols.

It will explain what is the basic architecture of an ad-hoc network based on the protocols of this type of networks such as OLSR and AODV.

Lecture or master classes (big groups):

The methodology to be followed in these classes in a large group will be a mix between master classes and the exhibition of theory and general examples in the classroom designated for the subject by the center.

Also, current news related to the contents of the subject will be shown, which will be inserted in a forum of the virtual platform by the students and the teacher. This work assumes that students perform search and research in online media to obtain news related to the technologies addressed in the subject and its social effects. They must self-evaluate the notoriety and adequacy of the news before they add them in the forum where they can include some optional comments. In the classes will be established debates about the most outstanding news that will promote discussions and group work in order to obtain common conclusions. This methodology allows students to be informed of the latest developments and trends related to the subject, they can also evaluate the message chains of the news created in the virtual platform by other students or the teacher. This way, a ranking will be established that will allow selecting the best rated news as part of the content to evaluate.

Students must follow the teacher's presentation with the material given for this purpose, either notes or slide presentation, which must be completed with their own notes and with the subsequent revision of the basic and / or recommended bibliography.

The attendance, as well as the active, respectful and responsible participation, either to raise doubts or to respond to the requirements or questions of the teacher, will be positively evaluated in its corresponding factor.

The student's autonomous work should focus on:

• Review of the concepts and theoretical aspects seen in the class
• Performing exercises
• Study of the theoretical concepts with the material contributed by the teacher, student notes and bibliography
• Research and online reasoned search for news related to the subject for inclusion in the appropriate forum.

Classes in small group
Work in the laboratory may take place in different ways, although in most of them a project-based learning methodology is used. The teacher will establish specifications that students, in groups of 2, must carry out. This type of work will focus on the development of applications, configuration of programs or learning tasks designated by the teacher, culminating in the completion or use of programs and client devices or servers, to meet the objective of the corresponding practice. Therefore, during the practice sessions, the design and implementation work of the applications marked by the different practices must be carried out fundamentally. At all times, students can receive help thanks to the supervision of the teacher. Additionally, there is another series of works in which the students will elaborate questions and evaluation tests that will be shown and used among the students.
The attendance, as well as the active, respectful and responsible participation, either to raise doubts or to respond to the requirements or questions of the teacher, will be positively evaluated in its corresponding factor.
Regarding self-employment, it will focus on:

• Reading of the guides of each practice before attending the corresponding session.
• Preparation of the documentation to be delivered of each practice when it can not be done in the laboratory itself.
• Complete the work started in the laboratory and that could not be finished in the corresponding session.

Collective / individual tutorials
The individual tutorials will serve both for the resolution of doubts, explanation of practices and for the monitoring and supervision of the works and memories to be developed during the academic period of the subject.
The collective tutorials will be used in the resolution of doubts, monitoring and supervision of the works and exercises as well as in attendance and participation in different seminars, talks, conferences, workshops and / or conferences, designated by the teacher, in order to complete the training and obtaining general, transversal and / or specific competences defined for this activity.
Attendance, as well as active, respectful and responsible participation in the aforementioned activities, will be evaluated according to the provisions of section 7 (Evaluation System) of this guide.

Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support.

OVERALL EVALUATION
The overall evaluation will be carried out according to the activities shown in the table of the evaluation system section.
To pass the subject, the student must obtain a mark equal to or greater than 5.0 out of 10 in the total computation of the evaluated aspects, as long as the student has a mark equal to or greater than 4.0 in each of these aspects.
The percentages and aspects evaluated in each activity are described in detail below:

S1 Attendance and Participation (10%):

• Assistance to theory classes and laboratory sessions (Up to 50% of S1).
• Participation in the virtual teaching platform in news and generalist forums (x1) and in the wiki glossary edition (x3) (Up to 50% of S1).
• Assistance to collective tutorials in which you attend seminars, visits to companies, or other activities, organized by the Telecommunications Engineering Department, E. P. S. de Linares, or University of Jaén and recommended by the teacher responsible for the subject.

The student must demonstrate that she/he has acquired the skills and competences defined for the subject (CG2, CG3, CG4, CG6, CG9, C7, C14, TEL2, TEL6, and TEL7).

S2 Theoretical concepts of the subject (30%) and S3 Completion of Works, Cases or Exercises (30%):

• During the course online tests will be carried out in the virtual teaching platform during some laboratory sessions. These tests will deal with the theory and general problems of the subject, including the contents of the current news (S2 and S3). The weight of these tests in the final mark  will be 100% of each aspect evaluated when the total result supposes the passing of the subject. Otherwise it will be 50% and the student must perform a final test described below.
• At the end of the semester, students who have not passed the course but have completed continuous assessment activities will make a final test of the theoretical part, news and problems of the subject (S2 and S3). The weight of this test in the final mark will be 50% of each aspect evaluated. This test may also be done by students who, although they have passed the subject in continuous evaluation, want to obtain another grade, in which case it may be higher or lower, depending on the weighted averages as indicated here.

The student must demonstrate that she/he has acquired the skills and competences of the subject (CG2, CG3, CG4, CG6, CG9, C7, C14, TEL2, TEL6, and TEL7).

S4 Laboratory / Computer Practices (30%)

• Compliance of laboratory work and Delivery of work / Exercises (70% of this part). The student must demonstrate that she/he has acquired the skills and competences of the subject (CG2, CG3, CG4, CG6, CG9, C7, C14, TEL2, TEL6, and TEL7).
• Check and delivery of exercises and questions in the virtual teaching platform (30% of this part). The student must demonstrate that she/he has acquired the objective skills and competences of the subject (CG2, CG3, CG4, CG6, CG9, C7, C14, TEL2, TEL6, and TEL7).

The marks obtained in the OVERALL evaluation will be maintained until the end of the course.

The student will have the option to renounce the OVERALL evaluation and it is not possible to return to it once the resignation has been made.

FINAL EXAM EVALUATION

In the modality of evaluation based on a final exam, an evaluation test will be presented that will cover all the contents of the subject, being necessary to guarantee that the student has acquired the competences and learning results established in the subject. This test is divided into 2 parts, whose assigned weight is explained below:

• Attendance and participation, theoretical concepts of the subject and related to current news and work, cases or exercises (S1, S2 and S3): 70%.
• Laboratory/computer lab (S4): 30%.

Those students, who have passed the part of laboratory / computer practices of the subject (S4) through OVERALL EVALUATION with a mark equal to or higher than 5.0 out of 10, will not have to complete the part corresponding to this aspect in the exam, applying the same mark obtained for this aspect in the OVERALL EVALUATION.

To pass the subject, the student must obtain a mark equal to or greater than 5.0 out of 10 in each of the two parts of this test.

The parts successfully completed with a mark higher or equal to 5.0 will be considered passing during that academic year.
