To study the limitations of transport protocols used on the Internet in mobility scenarios and analyze the various existing solutions in the literature. Knowledge to perform the simulation of transport protocols with mobility support in IP networks in the laboratory. Study the architecture and operation of wireless communication networks in a convergence scenario. Study the Protocol SIP/SDP. Knowledge to implement a communication system based on SIP/SDP protocols.
Syllabus:
Mobility in IP networks: Introduction, MIPv4, MIPv6, Micro Mobility, Mobility in Ad-Hoc and “Mesh” networks, and other mobility models. Support for mobility in the transport layer: Traditional TCP, Implications of mobility, Classical TCP improvements. The networks of the future: Introduction, Evolution and convergence of wireless communication networks.
Demonstration of the Syllabus Coherence with the Curricular Unit's Objectives:
The syllabus presented is consistent with the learning objectives of the curricular unit since there is a large convergence between the table of contents and the knowledge that the student is supposed to acquire in each of the program topics. The fundamental concepts of mobility in IP networks are presented in the first chapter. Then, the limitations of transport protocols used on the Internet in mobility scenarios are studied and some alternatives are analyzed. Finally, wireless telecommunications networks in a convergence scenario are presented. The learning objectives are achieved by supplementing the theoretical concepts with concrete examples run in lab environment using simulators and network equipment
Teaching Methodologies (Including Evaluation):
The transmission of knowledge in this syllabus will be with theoretical oriented lectures and practical classes in laboratory environment. The lectures present the fundamental concepts for understanding the items of the program. In practical classes students are confronted with real problems that need solving eventually resorting to physical or virtual equipment (in the context of simulators) where suitable. The assessment of the skills acquired by the student in this curricular unit consists of the following assessment elements: (1) Theoretical (2) Practical Projects (3) Exam(s) Continuous evaluation: Practical Grade (PG) = Average of the practical projects, Final Grade = ((1) + PG) /2, PG>=9.5 Exam Evaluation (PG>=9.5): Final Grade = (5)
Demonstration of the Coherence between the Teaching Methodologies and the Learning Outcomes:
The teaching/learning methodology applied in this curricular unit as well as its evaluation system is perfectly aligned with the objectives to be attained by the students at the end of the term. The theoretical concepts are presented, discussed, applied and evaluated in the context of lectures, which guarantees students a solid foundation to understand the challenges facing this area of knowledge. On the other hand, so that the study is not restricted to conceptual models, in the practical lessons are presented concrete case studies and implemented solutions for real problems using appropriate equipment and software tools. This combination guarantees training for students that allows them to meet the scientific goals, essential to a good understanding of the theme, as well as the ability to adapt to technological changes. The evaluation process consists of theoretical tests and practical work also guarantees a correct balance between the efforts dedicated to both components. The objective is to train professionals’ specialized in state-of-the-art techniques and tools but also ensure its ability to follow future developments. In this curriculum unit is studied the problem of mobility in wireless communication networks. The program begins by addressing the mobility support protocols over IP networks. Then are studied the main limitations and alternatives to transport protocols in wireless networks with mobility. Finally, it is studied the architecture of the telecommunications networks of the future in a convergence scenario and the use of the SIP/SDP protocols. These concepts are then applied in the resolution of the worksheets and practical work in the context of practical classes.
