    • Auction mechanisms for network resource allocation 

      Koutsopoulos, I.; Iosifidis, G. (2010)
      In the autonomic Internet of the future, auction mechanisms arise as key methods for realizing efficient resource allocation. The major asset of auctions is their obliviousness to node utilities, which renders them capable ...

    • Change detection and convolution neural networks for fall recognition 

      Georgakopoulos S.V., Tasoulis S.K., Mallis G.I., Vrahatis A.G., Plagianakos V.P., Maglogiannis I.G. (2020)
      Accurate fall detection is a crucial research challenge since the time delay from fall to first aid is a key factor that determines the consequences of a fall. Wearable sensors allow a reliable way for motion tracking, ...

    • Cooperative approaches for dymanic wireless charging of Electric Vehicles in a smart city 

      Maglaras, L. A.; Topalis, F. V.; Maglaras, A. L. (2014)
      In this paper, a method of electric vehicles charging with the use of large truck/bus vehicles moving along national highways and provincial roads is proposed and described. The method relies on charging vehicles from ...

    • Deep learning and change detection for fall recognition 

      Tasoulis S.K., Mallis G.I., Georgakopoulos S.V., Vrahatis A.G., Plagianakos V.P., Maglogiannis I.G. (2019)
      Early fall detection is a crucial research challenge since the time delay from fall to first aid is a key factor that determines the consequences of a fall. Wearable sensors allow a reliable way for daily-life activities ...
