    • The Algorithmic Aspects of Network Slicing 

      Vassilaras S., Gkatzikis L., Liakopoulos N., Stiakogiannakis I.N., Qi M., Shi L., Liu L., Debbah M., Paschos G.S. (2017)
      Network slicing is a technique for flexible resource provisioning in future wireless networks. With the powerful SDN and NFV technologies available, network slices can be quickly deployed and centrally managed, leading to ...

    • Finger detection and hand posture recognition based on depth information 

      Poularakis, S.; Katsavounidis, I. (2014)
      In this work, we propose a novel framework for automatic finger detection and hand posture recognition, based mainly on depth information. Our method locates apex-shaped structures in a hand contour and deals efficiently ...

    • In-Network Congestion Control for Multirate Multicast 

      Paschos G.S., Li C.-P., Modiano E., Choumas K., Korakis T. (2016)
      We present a novel control scheme that dynamically optimizes multirate multicast. By computing the differential backlog at every node, our scheme adaptively allocates transmission rates per session/user pair in order to ...

    • Information-Centric Connectivity 

      Katsaros K.V., Sourlas V., Psaras I., Rene S., Pavlou G. (2016)
      Mobile devices are often presented with multiple connectivity options, usually making a selection either randomly or based on the wireless medium's conditions, as is the case for current offloading schemes. In this article ...

    • An X Band Radio Channel Model for Propagation Through the Solar Corona 

      Stocker A.J., Siddle D.R., Warrington E.M., Mariotti G., Silvestri D., Zeqaj A., Tortora P., Argyriou A., De Vicente J., Abello R., Mercolino M. (2018)
      Spacecraft communication systems operating at X band are strongly affected when the propagation path passes close to the Sun (which can be characterized by the Sun-Earth-Probe, SEP, angle). In this paper, a channel model ...
