MEC-Assisted panoramic VR video streaming over millimeter wave mobile networks

Liu Y., Liu J., Argyriou A., Ci S. (2019)

Panoramic virtual reality video (PVRV) is becoming increasingly popular since it offers a true immersive experience. However, the ultra-high resolution of PVRV requires significant bandwidth and ultra-low latency for PVRV ...

Modeling influence with semantics in social networks: A survey

Razis G., Anagnostopoulos I., Zeadally S. (2020)

The discovery of influential entities in all kinds of networks (e.g., social, digital, or computer) has always been an important field of study. In recent years, Online Social Networks (OSNs) have been established as a ...

On self-organising mechanisms from social, business and economic domains

Hassas, S.; Marzo-Serugendo, G. D.; Karageorgos, A.; Castelfranchi, C. (2006)

This paper discusses examples of socially inspired self-organisation approaches and their use to build socially-aware, self-organising computing systems. The paper presents different mechanisms originating from existing ...

Optical wireless network convergence in support of energy-efficient mobile cloud services

Anastasopoulos, M. P.; Tzanakaki, A.; Rofoee, B. R.; Peng, S.; Yan, Y.; Simeonidou, D.; Landi, G.; Bernini, G.; Ciulli, N.; Riera, J. F.; Escalona, E.; Katsalis, K.; Korakis, T. (2015)

Mobile computation offloading has been identified as a key-enabling technology to overcome the inherent processing power and storage constraints of mobile end devices. To satisfy the low-latency requirements of content-rich ...

Optimal Trade-Off between Depth and Coverage for a Vertical UOWC Link

Christopoulou C., Sandalidis H.G., Vavoulas A. (2020)

The optimal trade-off between coverage and depth for a vertical underwater optical wireless communication (UOWC) link is thoroughly investigated in this letter. In the scenario under consideration, the optical transmitter ...

Optimised mobility tracking in current and future mobile networks

Korinthios J.A., Sykas E.D. (2017)

4th Generation (4G) Mobile Networks based on the All-IP paradigm are aggressively deployed worldwide and 5th Generation (5G) mobile networks will emerge in the forthcoming years. Signaling load optimization on the air-interface ...

People - Space - Technology: An Ethnographic Approach

Menezes M., Arvanitidis P., Kenna T., Ivanova-Radovanova P. (2019)

CyberParks aims at advancing knowledge on the relationship between information and communication technologies and the socially sustainable production and usage of public open spaces. Such research necessitates a solid ...

Policy instruments for coastal management in Greece

Mexa, A.; Coccossis, H. (2003)

Greece has the most extensive coastline among all Mediterranean countries and a large number of islands, some of which are quite small. Its coastal zone has significant value from both a socio-economic and ecological ...

Pricing Based Distributed Traffic Allocation for 5G Heterogeneous Networks

Passas V., Miliotis V., Makris N., Korakis T. (2020)

Next generation (5G and beyond) mobile networks will highly rely on distributed heterogeneous infrastructure, which is foreseen to create a versatile resource ecosystem. In such network deployments, efficient traffic ...

A programming model and runtime system for significance-aware energy-efficient computing

Vassiliadis, V.; Parasyris, K.; Chalios, C.; Antonopoulos, C. D.; Lalis, S.; Bellas, N.; Vandierendonck, H.; Nikolopoulos, D. S. (2015)

We introduce a task-based programming model and runtime system that exploit the observation that not all parts of a program are equally significant for the accuracy of the end-result, in order to trade off the quality of ...

Re-evaluating the energy consumption-economic growth nexus for the United States: An asymmetric threshold cointegration analysis

Kourtzidis S.A., Tzeremes P., Tzeremes N.G. (2018)
