T1 – The Path Towards 5G – Essential Technologies, Protocols and Tools for Enabling 5G Mobile Communications

The fifth-generation (5G) is coming. Quo vadis 5G? What architectures, network topologies and technologies will define 5G? Are methodologies to the analysis, design and optimization of current cellular networks still applicable to 5G? The proposed tutorial is intended to offer a comprehensive and in depth crash course to communication professionals and academics. It is aimed to critically illustrate and discuss essential and enabling transmission technologies, communication protocols and architectures that are expected to make 5G mobile communications a reality.
 

T2 – Network Coding for Cloud Storage and Content Delivery

The tutorial provides an introduction to the growing research area of network coding with emphasis on cloud storage and content distribution and is divided into three parts. The first part provides the participants with the theoretical tools necessary to understand the field of network coding, introduce distributed randomized network codes and their properties, as well as introduce the attendees to cutting edge network code structures. Among other things, the tutorial shall show that network coding can be used to increase throughput and robustness as well as reduce storage requirements, delay, and energy consumption. The second part of the tutorial introduces key issues in cloud storage and content delivery that are amenable to network coding. The tutorial covers practical challenges that range from the storage repair problem and confidentiality issues to content availability and efficient content download. Finally, we will discuss implementation aspects in real‐world systems ranging from core network routers and caches down to mobile phones, which impose considerably different restrictions in terms of memory, computing power, and connectivity. The instructors have a large experience holding tutorials in high‐impact IEEE conferences, particularly, in the area of network coding. This is their first tutorial focused specifically on cloud storage and content delivery.
 

T3 – Multi-Carrier waveforms: State of the Art and Challenges in a 5G perspective

OFDM has become an essential technological component in the beginning of the nineties due to its nice features. And it has been adopted in various wired and wireless standards, including leading applications: ADSL, DVB-T, WiFi, Wimax, LTE, etc. However, OFDM leaves room to some potential improvements, particularly with respect to its poor frequency localization. The aim of this tutorial is to provide an overview of the large set of CP-OFDM variants covering the most recent achievements in the related domain. Among the potential alternatives we have FBMC schemes using OQAM coding, FMT and, more recently, MCM schemes based on cyclic convolution with CB-FMT, GFDM and WCP-COQAM. Our tutorial provides a comparison among these candidates from different aspects. For each scheme, we point out the advantages/disadvantages as well as the potential use cases towards 5G mobile system. Most of these alternatives are actively under development in well-known leading European projects towards 5G, e.g., METIS and 5GNOW.
 

T4 – Small Cells and Device-to-Device Networks towards the 5G Era: Fundamentals, Applications, and Resource Allocation using Game Theory

5G networks are considered one of the hottest topics among wireless networks researchers and engineers. Though it is still unclear what exactly a 5G network will look like and what services it will offer, there are many issues that there is broader consensus on: To support the massive growth of connected devices, 5G networks should be denser and new communication paradigms should arise and be exploited. 

In this tutorial, after providing an overview of the fundamentals of 5G networks, along with a presentation of use cases and recent prototypes and trials, we focus on small cells and device-to-device communications that are expected to be key technologies in the forthcoming 5G era. We provide a thorough review of their attributes and advantages, we discuss classifications and we present key deployment scenarios.

Then, we describe (non-)cooperative game-theoretic solutions in resource allocation problems (power control, rate adaptation, medium access, and spectrum access) under different practical constraints in such wireless networks. Finally, we discuss licensed spectrum sharing scenarios using game theory.
 

T5 -Understanding the IoT evolution to master the IoT revolution

The Internet of Things (IoT) has undergone different evolutions since its birth dated back to the first years of last decade. In fact, in the beginning the IoT was identified just as a system capable of tracking objects through RFID tags. Then, many other technologies have been added to augment the capabilities of the IoT systems to monitor and control the physical world entities. As a result, many technological approaches and visions have been proposed, which are sometimes in contrast with each other and, thus, generate confusion on the real role and features of the IoT. Objective of this tutorial is to present the evolution of the IoT from its infancy, represented by the EPCglobal Network, to its most recent instantiations proposed in the literature, and thus to give a modern definition of the ioT phenomenon highlighting the differences between IoT and the technologies often confused with it (Sensors, RFID, M2M, etc). Based on the resulting analysis, the tutorial will present how the emerging computing and communication paradigms (e.g., Information Centric Networking, Social Networks, Cloud computing, etc.) are influencing the IoT in terms of architectures, technologies and protocols.
 

T6 – Efficient Network Handling Techniques on Android Platform

The goal of this tutorial is to give a deep overview about the efficient level networking capabilities of the Android platform. The tutorial gives introduction for both „short-range” (WiFi Direct, Bluetooth, NFC, etc.) and „long-range” communication (TCP/IP, UDP). (1) First we give a quick introduction about the network handling capabilities of the Android platform and we highlight the common rules how network handling should be implemented with Threads, Services, AsyncTasks, etc. (2) After that short range communication techniques are introduced. First we start with NFC and we demonstrate how NFC reading and writing can be implemented, we also show how NFC Beam can be implemented between two devices. (3) This will be followed by a Bluetooth and Wifi Direct overview. We show with coding examples how those communications can be implemented, what are the differences and what are the advantages and disadvantages. (4) Finally the TCP-IP and UDP communication will be demonstrated via a small project. We show the best practices for efficient communication and we highlight how the communication can be extended/customized for our own purposes. In addition to that we demonstrate how easy is to transfer simple objects over the network for any purposes.
