    • Green collaboration in cognitive radio cellular networks with roaming and spectrum trading 

      Sboui, Lokman; Ghazzai, Hakim; Rezki, Zouheir; Alouini, Mohamed Slim ( Institute of Electrical and Electronics Engineers Inc. (IEEE) , 2015 , Conference)
      In this paper, we propose a new cognitive cellular network architecture based on the coexistence of primary and secondary networks, (PN) and (SN), respectively. The PN aims to minimize its energy consumption by switching ...

    • Optimized energy procurement for cellular networks powered by smart grid based on stochastic geometry 

      Farooq, Muhammad Junaid; Ghazzai, Hakim; Kadri, Abdullah ( Institute of Electrical and Electronics Engineers Inc. (IEEE) , 2015 , Conference)
      In this paper, we investigate the energy procurement decision of cellular networks powered by smart grid. Multiple retailers producing energy from different sources characterized by their prices and pollutant emission ...

    • Seven Challenges for Communication in Modern Railway Systems 

      Yaacoub, Elias; Alsharoa, Ahmad; Ghazzai, Hakim; Alouini, Mohamed Slim ( Frontiers Media S.A. , 2020 , Article)
      To meet the increasing demands for passenger data rates, modern railway communication networks face significant challenges. The advent of 5G communications after the long-term evolution (LTE) and LTE-Advanced (LTE-A) systems ...

    • A stochastic geometry-based demand response management framework for cellular networks powered by smart grid 

      Farooq, Muhammad Junaid; Ghazzai, Hakim; Kadri, Abdullah ( IEEE , 2016 , Conference)
      In this paper, the production decisions across multiple energy suppliers in smart grid, powering cellular networks are investigated. The suppliers are characterized by different offered prices and pollutant emissions levels. ...
