    • Area spectral efficiency of cooperative network with DF and AF relaying 

      Zhang L.; Yang H.-C.; Hasna , Mazen ( IEEE , 2012 , Conference Paper)
      Most performance metrics for cooperative networks focus on the qualification of either spectrum efficiency or link reliability, without considering the spatial effect of radio transmission. Area spectral efficiency (ASE) ...

    • Area spectral efficiency of cooperative network with opportunistic relaying 

      Zhang L.; Hasna , Mazen; Yang H.-C. ( IEEE , 2012 , Conference Paper)
      In this paper, we investigate the area spectral efficiency (ASE) in a three-node cooperative network with opportunistic relaying. On one hand, in conventional cellular network, ASE is defined to be the average data rate ...

    • Atmospheric turbulence effect on hybrid FSO/RF systems 

      Touati A.; Hussain S.J.; Touati F.; Bouallegue A. ( IEEE Computer Society , 2017 , Conference Paper)
      This article is focused on the atmospheric turbulence attenuation and their effect on the hybrid free space optical and radio frequency (FSO/RF) under Qatar harsh and dry climate. Analysis has been done by calculating the ...

    • Cognitive relaying in wireless sensor networks: Performance analysis and optimization 

      Elsaadany M.; Abdallah M.; Khattab T.; Khairy M.; Hasna , Mazen ( IEEE , 2010 , Conference Paper)
      The anticipated increase in the density of the deployed wireless sensor networks calls for spectrum sharing through unlicensed access to licensed spectrum. The key technology for spectrum sharing in this scenario is cognitive ...
