Impact of Inter-Operator Interference via Reconfigurable Intelligent Surfaces

Autor: Miridakis, Nikolaos I., Tsiftsis, Theodoros A., Karkazis, Panagiotis A., Leligou, Helen C., Popovski, Petar

A wireless communication system is studied that operates in the presence of multiple reconfigurable intelligent surfaces (RISs). In particular, a multi-operator environment is considered where each operator utilizes an RIS to enhance its communicatio

Extreme Level Crossing Rate: A New Performance Indicator for URLLC Systems

Autor: Miridakis, Nikolaos I., Tsiftsis, Theodoros A., Karkazis, Panagiotis A., Leligou, Helen C., Foukalas, Fotis

Level crossing rate (LCR) is a well-known statistical tool that is related to the duration of a random stationary fading process \emph{on average}. In doing so, LCR cannot capture the behavior of \emph{extremely rare} random events. Nonetheless, the

Evaluation of a blockchain-enabled resource management mechanism for NGNs

Autor: Xevgenis, Michael, Kogias, Dimitrios, Christidis, Ioannis, Patrikakis, Charalampos, Leligou, Helen C.

Publikováno v: International Journal of Network Security & Its Applications (IJNSA) Vol.13, No.5, September 2021

A new era in ICT has begun with the evolution of Next Generation Networks (NGNs) and the development of human-centric applications. Ultra-low latency, high throughput, and high availability are a few of the main characteristics of modern networks. Ne

Semi-Blind Multiuser Detection Under the Presence of Reconfigurable Intelligent Surfaces

Autor: Miridakis, Nikolaos I., Tsiftsis, Theodoros A., Yang, Guanghua, Karkazis, Panagiotis A., Leligou, Helen C.

A multiuser multiple-input multiple-output wireless communication system is analytically studied, which operates with the aid of a reconfigurable intelligent surface (RIS). The intermediate RIS is equipped with multiple elements and operates via rand

Secure Open Federation of IoT Platforms Through Interledger Technologies -- The SOFIE Approach

Autor: Lagutin, Dmitrij, Bellesini, Francesco, Bragatto, Tommaso, Cavadenti, Alessio, Croce, Vincenzo, Kortesniemi, Yki, Leligou, Helen C., Oikonomidis, Yannis, Polyzos, George C., Raveduto, Giuseppe, Santori, Francesca, Trakadas, Panagiotis, Verber, Matteo

The lack of interoperability among IoT platforms has led to a fragmented environment, where the users and society as a whole suffer from lock-ins, lack of privacy, and reduced functionality. This paper presents SOFIE, a solution for federating the ex
