Objective

This course aims to analyze the fundamental techniques and advance infrastructure technologies for the Future Internet. The first part of the course addresses physical layer aspects: modulation, coding, multiplexing and diversity techniques. The second part of the course addresses multiple access schemes, resources and interference management techniques. In the third part, architectural aspects are studied, placing the emphasis on the cellular, local area network and proximal communications (i.e. wireless sensor networks, machine to machine and device to device communications) infrastructures paradigms. In the last part, architectural challenges and bottlenecks in the design of Future Internet Infrastructures are discussed, namely backhaul and latency limitations, centralization requirements, virtualization and heterogeneity.
