Keynote #1

Title: Cloud – Fog Computing: Resource Allocation and Scheduling Challenges

Cloud computing has been widely used in research, industry, business, etc., due to its virtually unlimited processing and storage capabilities. Resource allocation and application scheduling play a vital role in cloud computing.

Due to the growing increase in number of Internet of Things (IoT) applications, fog computing has appeared as a computing model aiming to alleviate problems in cloud computing related to network congestion and latency of services. Fog is an intermediate tier between users and cloud resources, with limited processing capacity. However, most of the IoT applications are real-time having timing constraints as main concern. Therefore, appropriate management of real-time applications is required for effective use of cloud and fog resources.
The motivation of this keynote is to present novel techniques to address challenges in resource allocation and scheduling in cloud and fog computing architectures and to provide future research directions in the areas of cloud and fog computing.

Keynote #2

Title: Mobile Crowd Sensing (MCS) – a first step towards building collective intelligence

In this presentation, we will focus on the discussion of the concept of “crowd sensing”, as an approach to collect data from embedded sensors in smartphones. Its positioning as a first, inexpensive, step for the building of a collective intelligence makes it a tool that is more and more popular today. This emergent paradigm comes with various applications, most of which related to Smart City processes. However, many challenges arise given users involvement in the data collection process. In this context, we will try throughout this presentation to discuss collaborative sensing schemes which tackle the following four main questions: How to assign sensing tasks to maximize data quality with energy-awareness? How to minimize the processing time of sensing tasks? How to motivate users to dedicate part of their resources to the crowdsensing process? and How to protect participants privacy and not impact data utility when reporting collected sensory data?

Keynote #3

Title: AI-Enabled Wireless Networks: A Bridge from 5G to 6G

Future wireless networks are expected to support a multitude of services demanded by Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low-latency Communications (uRLLC), and massive Machine Type Communications (mMTC) users. Heterogeneous devices with different quality of service (QoS) demands will require intelligent and flexible allocation of network resources in response to network dynamics. For instance, a highly reliable and low-latency network is needed to enable rapid transfer of messages between connected autonomous vehicles. At the same time, the same physical infrastructure is expected to serve users with high-quality video demand or even mobile Augmented/Virtual Reality entertainment applications. Next-generation wireless networks are expected to accommodate such diverse use cases. In addition, resource efficiency, reliability, and robustness are becoming more stringent for 5G and beyond networks. To meet this, future wireless networks must incorporate a paradigm shift in network resource optimization, in which efficient and intelligent resource management techniques are employed. Artificial intelligence, or more specifically machine learning algorithms stand as promising tools to intelligently manage the networks such that network efficiency, reliability, robustness goals are achieved and quality of service demands are satisfied. The opportunities that arise from learning the environment parameters under varying behavior of the wireless channel, positions AI-enabled 5G and 6G, superior to preceding generations of wireless networks. In this keynote, we will provide an overview of the state-of-art in machine learning algorithms and their applications to wireless networks, in addition to their challenges and the open issues in terms of their applicability to various functions of future wireless networks.

Keynote #4

Title: Small data transmission in 5G New Radio (NR) systems: Applications, design and performance evaluation


First, I will provide an overview of the fundamentals of the 5th Generation (5G) Radio Resource Control (RRC) protocol, responsible for fundamental functions in the user equipment (UE) such as state handling (e.g. Idle, Connected, Inactive states), Control Plane procedures (e.g. state transitions), measurement configuration and reporting, mobility, etc.

Then, I will describe the design of Small Data Transmission (SDT) in 5G NR, a new feature recently addressed by the 3rd Generation Partnership Project (3GPP) specification Release 17 which enables UEs in RRC Inactive state to transmit infrequent and small data without requiring an RRC state transition. 

Finally, I will conclude with performance results that show significant gains in latency reduction and energy efficiency which are critical requirements for many 5G use cases.
