    • 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) ...

    • Using a HAP Network to Transfer WiMAX OFDM Signals: Outage Probability Analysis 

      Vaiopoulos, N.; Sandalidis, H. G.; Varoutas, D. (2013)
      Transferring wireless broadband services across extremely far distances on Earth is usually implemented nowadays either by ground-based or satellite communications. Terrestrial networks require, however, heavy installation ...

    • WiMAX on FSO: Outage Probability Analysis 

      Vaiopoulos, N.; Sandalidis, H. G.; Varoutas, D. (2012)
      The transmission of multiple wireless signals over optical links has attained a great research interest nowadays. In case where optical fibers are difficult to be deployed, or installation cost is prohibited, optical ...
