Special Tracks and Areas of Interest

  • Security and Performance in Computer and Telecommunication Systems
       Chairs: Jean-Pierre Seifert, Altaf Shaik, Robert Buhren

    Data security is vital to ensure protection against cyber threats that continue to raise and diversify at a rapid speed. But often, while deploying security mechanisms, the performance of the system is affected in adverse ways. A key challenge in the design of computer and telecommunication systems is to identify a neutral ground between security and performance. Whilst the widespread of devices spanning into networks and generating countless amounts of data absolutely require high performance systems. This makes us to rethink our security systems that can guarantee a high level of performance and also an acceptable level of security. In this respect, we invite researchers and security enthusiasts to submit papers that study and analyze various issues but not limited to such as tradeoff between security and performance, new security protocols in secure communication systems.

  • Edge Computing and Edge-enabled AI for Network Management
       Chairs: Paolo Bellavista, Luca Foschini, Carlo Giannelli

    Edge computing is rapidly emerging as the most relevant architectural approach to manage some hard and open technical challenges associated with wide-scale and quality-sensitive Internet of Things (IoT) applications, which typically exploit the elastic availability of cloud resources on the server side. EAINM specifically focuses on network quality configuration, optimization, configuration, control, and management enabled by edge computing in three-layer deployment environments (device, edge, cloud). In particular, EAINM considers as central all methodological, design, implementation, and deployment experiences that investigate digital twin creation at the cloud layer and distributed enforcement of twin control actions also at the edge, typically with complex machine learning processing at the cloud side and more lightweight digital twin execution and refinement at edge nodes. Contributions about enabling AI techniques for these architectures and practical application prototyping/deployment experiences (e.g., for manufacturing production quality control and optimized management of distributed caching) are strongly welcome.

  • Aspects and trends of software evaluation
       Chairs: George Tsihrintzis, Maria Virvou

    Software applications are evolving rapidly and are expanding their use to all the areas of human activity by the means of all sorts of hardware, including computers, handheld devices, smart things, digital signage etc. The vast use of software in many contexts imposes the need for the development of new evaluation methodologies, frameworks and processes to address software quality characteristics that include reliability, reusability, effectiveness, correctness, accuracy and also security and privacy that conform to new law regulations. Moreover, the important software quality characteristics of usability, user friendliness and utility have to be ensured for end users of a vast range of disciplines and backgrounds. Thus, measuring and evaluating the quality of software applications has become of critical importance and should attract a lot of research energy. The aim of ASE is to address current aspects and trends of software evaluation.

  • Modeling and Evaluation of Wireless Body Area Networks
       Chair: Yahya Osais

    Wireless Body Area Not (WBAN) are networks of medical sensors which are attached or implanted into the body of a human being or animal to monitor and control biological processes. Their performance is limited by their constrained resources and side effects such as heat. Before the full potential of WBANs can be realized, many fundamental issues must be studied using performance evaluation tools and measurements. The aim of MEWBAN is to provide the necessary insights to make the needed progress.

  • Social Network Analysis and Performance Aspects of Socially-Aware Networking
       Chairs: Magdalini Eirinaki, Iraklis Varlamis, Malamati Louta

    The rapid development of wireless communications and the rise of social networks established a new research field that stands between telecommunications and social network theory. Smart and wearable mobile devices act as alternative gateways for participation in social networks and introduced “mobility” as a new aspect of social networking and applications. The aim of SANet is to provide a forum where researchers from the fields of Social Network Analysis and Telecommunication Systems Performance will come together, exchange ideas and generate new collaborations that bring us a step closer to Socially-Aware Networking.

Using any Surface to Realize a New Paradigm for Wireless Communications, through Software-controlled Metasurfaces


Wireless communications is undeniably becoming ubiquitous in everyday life, with user demands growing at a very fast pace. Despite impressive breakthroughs in almost every part of our wireless systems-from antennas to hardware to operating software-this demand is getting increasingly challenging to address. The humongous scale of research effort and investment in the upcoming 5th generation of wireless communications (5G) reflects the scale of the challenge. This talk will introduce a valuable and unnoticed resource, which could be exploited to tackle these increasing challenges.

Wireless communication environments, i.e., the set of physical objects (such as walls, doors, desks, and humans) that stand between two wireless communicating devices, are unaware of the ongoing data exchange efforts within them. Moreover, their effects on the communication quality are intractable in all but the simplest cases. These ensuing effects are degenerative, due to such phenomena as the path loss, the multi-path scattering, and the Doppler effect, exacerbated as operating frequencies scale up, e.g. mm-wave solutions for 5G. Existing proposals for mitigating these effects generally tackle the problem by adopting device-side approaches, treating the environment as an uncontrollable factor that does not participate into the communication process. Examples include device-oriented (e.g. MIMO techniques, real-time adaptation of signal modulation and coding), and retransmitter-oriented (e.g. intelligent placement of passive or active amplifiers) techniques. These effects, as well as different approaches to minimize them, and their inability to tackle the problem at its root, will be briefly overviewed.

Next, the talk will introduce a new approach that could control these effects, producing a wireless environment with software-defined electromagnetic behavior. The novel idea of HyperSurfaces*, which are software-controlled metamaterials embedded in any surface in the environment (e.g. by coating walls, doors, furniture, poles, and other objects) will be motivated. HyperSurfaces are envisioned to realize a new generation of applications, as for example programmatically controlled wireless environments, realizing application related functionalities such as perfect absorption, beam steering via anomalous reflection, or polarization control. These materials can interact with electromagnetic waves in a fully software-defined fashion, even unnaturally. Thus, the electromagnetic behavior of the environment as a whole can become deterministic, controlled and tailored to the needs of mobile devices within it. HyperSurfaces have inter-networking capabilities, allowing for the first time the participation of electromagnetic properties of materials into control loops, leading to the concept of the Internet of Smart Materials. Our solution will be briefly contrasted with closer in concept approaches, such as phased antennas and reflect arrays, which can only support coarse EM steering, e.g., for beamforming applications in wireless devices.

Beyond the conceptual introduction of the topic, a specific application scenario of a Programmable Wireless indoor Environment (PWE) will be presented, from inception to design to evaluation in 2.4 and 60 GHz setups.

In conclusion the talk will highlight the substantial gains in communication quality, communication distance and battery savings of mobile devices, and even in security and privacy, will discuss open problems and plausible research directions, as well as outline its potential application in diverse areas, as e.g. highly efficient energy harvesting photovoltaics, and thermophotovoltaics, ultra-high resolution medical imaging, sensing, quantum optics and military applications.

Open discussion with the audience will be encouraged.
