Description: This course covers issues and problems that can be identified in PhD projects in relation to communication networks from a practical point of view.

Communication networks have increasingly become an essential part of our everyday lives and currently, our society is highly dependent on the proper functioning of these. Therefore, future networks should allow a wide range of network and Internet-oriented services and applications to be carried over the same infrastructure. Networks are everywhere and in many domains their impacts cannot be ignored.

The course will be introducing methods for analysis, design, and simulation of high performing future network infrastructure, ranging from the user side to the core of the network. The main objective is to provide the student with general knowledge about how to face and solve problems in relation to these tasks. The course is targeting students working in the network domain as well as students working who apply networking and network infrastructures in their projects. The course consists of three parts with the following focus points:

• Broadband access, wired network planning and applied graph theory:
Overview of current and future optical transport and access network technologies will be given, including future trends and challenges. Guidelines, methods, and tools to design and analyse network infrastructure will be presented. Graph theory applications for communication networks will be covered in depth. Examples and brief assignments will be given along the course to consolidate the presented concepts.

• Wireless Network Planning, Optimization and Evolution:
Wireless network is going to play a more and more important role of connecting peoples and devices into the Internet in the future. Deployment of wireless network is tricky because each deployment scenario is a unique radio frequency environment, which requires careful planning and optimization. Multiple wireless technologies are available making the evolution path less obvious. This course offers concepts and practical guidelines for evaluating the performance of wireless technologies in a big picture. The purpose is to identify current and future capacity and coverage problems, and to provide optimum solutions for operators.

• Application and Simulation:
Network simulation will be introduced, focusing on ns-3 where we will give an overview of the most important features of ns-3. Practical tools, examples, and exercises of how these aspects can be modeled are also provided.

The material taught in each of the parts will be practically applied in group assignments. These will be introduced in the lectures and must be finalized after the lecture days.

What is ns-3?
ns-3 is a discrete-event network simulator, targeted primarily for research and educational use. ns-3 is free software, licensed under the GNU GPLv2 license, and is publicly available for research, development, and use. NS-3 is used for simulation of IP networks, wired and wireless (wi-fi/wimax/LTE), and contains PHY, MAC and NET layer implementations of various protocols and includes basic traffic generators. Depending on the used technologies, different statistical channel models are also available. Performance metrics such as throughput, end-to-end delay, etc. can be extracted from the simulation results.

Basic knowledge of networks and OSI layers and main networking functionalities corresponding to MSc in Electrical or Computer engineering.
