General description O obxectivo da asignatura é presentar os esquemas máis recentes en redes IP, redes de sensores (WSNs) e redes móbiles ad hoc (MANETs). Cúbrense aspectos como calidade de servizo (QoS), IPv6, redes privadas virtuais (VPNs), redes de sensores, redes MANET e os seus algoritmos de enrutado.

Assessment comments

Evaluation in the case of part-time students: the same as in the general case. 

At the second opportunity, only one final exam will be taken for the guest lecture / keynote speech methodology. The practical grade will be that obtained during the course through the continuous evaluation of the student's work.

Copying and/or plagiarism: art. 14 section 4b of the UDC regulations will be applied: "Qualification of failure in the exam session in which the offence is committed and with respect to the subject in which it is committed: the student will be qualified with "failure" (numerical grade 0) in the corresponding exam session of the academic year, whether the offence is committed at the first opportunity or at the second opportunity. To this end, the grade will be modified in the first opportunity report, if necessary".

All aspects related to ‘academic dispensation’, ‘dedication to study’, ‘permanence’ and ‘academic fraud’ will be governed in accordance with the current academic regulations of the UDC.
