Network systems & cybersecurity

The increasing tendency toward the extreme network densification has motivated network operators to leverage spectrum across multiple radio access networks, in order to significantly enhance spectral efficiency, quality of service, as well as network capacity. There is therefore a substantial need to develop innovative network selection mechanisms that consider energy efficiency while meeting application quality requirements. In this context, in accordance with the new trends foreseen for 5G systems, we propose different user-centric scheme for efficient network selection over D2D-enabled heterogeneous wireless networks. Our solutions account for network characteristics and application requirements, as well as for different user objectives by assigning them different weights and dynamically updating them.
