  • Distributed clustering in vehicular networks 

    Maglaras, L. A.; Katsaros, D. (2012)
    Clustering in vanets is of crucial importance in order to cope with the dynamic features of the vehicular topologies. Algorithms that give good results in Manets fail to create stable clusters since vehicular nodes are ...
  • Downlink multi-user transmission for higher user speeds in IEEE 802.16m 

    Papathanasiou, C.; Dimitriou, N.; Tassiulas, L. (2009)
    A dynamic resource allocation algorithm with beam steering is evaluated for providing broadband wireless access to mobile users of the emerging IEEE 802.16m air interface standard. Thanks to our design, the coverage area ...
  • Galvanomagnetic effects "Sensors based on hall effect" 

    Petousis, V. N.; Dimitropoulos, P. D. (2009)
    The Hall effect is the generation of a transverse electromotive force in a sample carrying an electric current and exposed to perpendicular magnetic field. Depending on the sample geometry, this electromotive force may ...
  • On the structure and evolution of vehicular networks 

    Pallis, G.; Katsaros, D.; Dikaiakos, M. D.; Loulloudes, N.; Tassiulas, L. (2009)
    Vehicular ad hoc networks have emerged recently as a platform to support intelligent inter-vehicle communication and improve traffic safety and performance. The road-constrained and high mobility of the vehicles, their ...
