• Cross-Layer Antenna Beamforming and Power Control in Wireless Uplinks 

      Tsoukatos, K. P.; Chrisanthopoulou, M. P.; Apostolaras, A. (2009)
      We consider backlog-driven power control and antenna beamforming as a means to maximize network throughput in a wireless uplink, where a base station receives with an antenna array from single-antenna wireless users. ...
    • Optimal Control of Sleep Periods for Wireless Terminals 

      Azad, A. P.; Alouf, S.; Altman, E.; Borkar, V.; Paschos, G. S. (2011)
      We consider a mobile connected to a base station, and study how to optimally schedule shutting off its transceiver. First, we study the model from optimal control perspective. We consider off-times (periods of inactivity) ...
