Recommended Prerequisites

Fundamentals of Communications.

Teaching Methods

Theoretical classes with detailed explanation, using audiovisual media, of concpets, fundamentals and tehories, complemented with practical exercises for application of the theoretical knowledge.

Practical classes to perform simulation studies, model creation and practical exercises.

Learning Outcomes

The main objective of this course is the study of methodologies for modeling and performance evaluation of communication networks. The course addresses fundamentals of probability theory and stochastic processes from the perspective of modeling and performance analysis of communication systems. This course also addresses simulation methodologies for the performance analysis of communication systems.

The students will acquire knowledge about fundamentals on modeling and network performance analysis, obtaining capabilities for the analysis and design of models of communication systems components. Students will acquire decision making capabilities in the selection and use of methodologies for modeling and performance evaluation of communication systems, being able to justify the options taken, as well as to express and explain the results obtained.
