Title: Spectrum sharing and networking issues in 5G mmWave cellular networks


This talk will discuss some relevant networking issues for 5G mmWave cellular systems. First, we will give an extensive discussion on the potential benefits and technical challenges of spectrum sharing in a mmWave context. We will show that from this points of view this scenario is much more promising than traditional cellular systems in sub-6 GHz bands. We will also discuss the role of coordination between different operators for the purpose of managing the inter- and intra-system interference, which is shown to be the ultimate limiting factor in spectrum sharing. Second, we will discuss how directionality makes it more difficult to implement and operate network management functionalities, with specific reference to Initial Access and Cell Search, where the energy/latency/detection tradeoff is of particular interest. Finally, we will briefly describe our full-stack 5G mmWave cellular simulator, which includes the whole protocol suite as well as detailed mmWave channel models, and present some examples of system-level results it can provide.

Title: Synthetic Molecular Communication for Future Nano-communication networks


Synthetic molecular communication is an emerging research area offering many interesting and challenging new research problems for communication engineers, biologists, chemists, and physicists. Synthetic molecular communication is widely considered to be an attractive option for communication between nano-devices such as (possibly artificial) cells and nano-sensors. Possible applications of nano-communication networks include targeted drug delivery, health monitoring, environmental monitoring, and "bottom-up² manufacturing. The IEEE and ACM have recently founded several new conferences and journals dedicated to this exciting new and fast growing research area.

In this keynote, we will give first a general overview of the areas of synthetic molecular communication and nano-networking. Components of synthetic molecular communication networks, possible applications, and the evolution of the field will be reviewed. Subsequently, we will give an introduction to various synthetic molecular communication strategies such as gap junctions, molecular motors, and diffusion based molecular communication. Thereby, we will focus particularly on diffusion based synthetic molecular communication, identify the relevant basic laws of physics and discuss their implications for communication system design. One particular challenge in the design of diffusive synthetic molecular communication systems is intersymbol interference. We will discuss corresponding mitigation techniques and provide some results. Furthermore, we will present several receiver design options for diffusive synthetic molecular communication, discuss their respective advantages and disadvantages, and elaborate on the impact of external phenomena such as molecule degradation and flow. In the last part of the talk, we will discuss some research challenges in synthetic molecular communication from a communication and networking point of view.

Title: Overview of Artificial Intelligence, Machine Learning and Big Data Analytics with applications in various decision-making environments


Artificial Intelligence (AI) can be defined in many ways, but one thing all experts agree upon is the key role machine learning plays in AI. This keynote will adopt a tutorial style to first provide a quick overview of the current state of AI and reviews in some details the main approaches followed in machine learning, with a special focus on the more recent advances in deep learning and neural networks. We will also present a hierarchical layered approach that exploits many types of sensor and non-sensor signals and data, and proposes suitable representations, as well as processing and analysis algorithms in order to apply machine learning, including deep and shallow learning. The framework can be explored in various decision-making environments, including healthcare and wellbeing, surveillance, and media and entertainment to mention a few fields.

Title: Robotic Communication: when Communication Theory meets Control Theory


Mobile robots (terrestrial and aerial) are gaining importance in an increasing number of applications. They often require wireless communication capabilities to complete their tasks, and in some applications the main task of the robot is communication/relaying of information. The conventional approach to adding communications capabilities to mobile robots does not leverage the fact that the robot can control its position and can hence move in such a way as to improve the communication performance through spatial/mobility diversity. Since the energy consumption due to mobility is tightly linked to the robot’s state vector transitions (kinematics and dynamics) over time, communication-aware path/trajectory planning requires a good knowledge of both control theory and communication theory. Therefore, designing efficient communication systems for mobile robots calls for a new paradigm where control theory plays a pivotal role. In this talk, this paradigm will be described and illustrated through examples, and new research opportunities will be presented.
