  • A converged network architecture for energy efficient mobile cloud computing 

    Tzanakaki, A.; Anastasopoulos, M. P.; Peng, S.; Rofoee, B.; Yan, Y.; Simeonidou, D.; Landi, G.; Bernini, G.; Ciulli, N.; Riera, J. F.; Escalona, E.; Garcia-Espin, J. A.; Katsalis, K.; Korakis, T. (2014)
    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 ...
  • Cross-layer design for power efficiency and QoS provisioning in multi-hop wireless networks 

    Kozat, U. C.; Koutsopoulos, I.; Tassiulas, L. (2006)
    In recent years, it has become common consensus that independent consideration of communication layers often turns out to be inadequate in terms of providing the desired quality of service (QoS) and power efficiency in ...
  • Energy aware buffer aided cooperative relay selection 

    Hadef, M.; Apostolaras, A.; O'Reillys, J.; Mourad, A.; Mouhouche, B.; Koutsopoulos, I.; Korakis, T.; Tassiulas, L. (2014)
    In this paper we evaluate an energy-aware relay selection mechanism which exploits channel state information and the availability of buffers at relays to perform flexible relaying based on a backpressure-driven optimization ...
  • The Impact of Transmit Rate Control on Energy-Efficient Estimation in Wireless Sensor Networks 

    Koutsopoulos, I.; Stanczak, S. (2012)
    We study the impact of physical layer (PHY) transmit rate control on energy efficient estimation in wireless sensor networks. A sensor network collects measurements about an unknown evolving process. Each sensor controls ...
  • Joint Task Migration and Power Management in Wireless Computing 

    Gitzenis, S.; Bambos, N. (2009)
    We investigate a wireless computing architecture, where mobile terminals can execute their computation tasks either 1) locally, at the terminal's processor, or 2) remotely, assisted by the network infrastructure, or even ...
