    • 5G wireless backhaul networks: Challenges and research advances 

      Ge, X.; Cheng, H.; Guizani, M.; Han, T. ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Article)
      5G networks are expected to achieve gigabit-level throughput in future cellular networks. However, it is a great challenge to treat 5G wireless backhaul traffic in an effective way. In this article, we analyze the wireless ...

    • A hardware implementation for efficient spectrum access in cognitive radio networks 

      Shabara, Yahia; Mohamed, Amr; Al-Ali, Abdulla K. ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)
      Opportunistic spectrum access is a propitious technique to overcome the under-utilization of spectrum bands. In this work, we design an experimental test-bed for evaluating an un-slotted spectrum access scheme under real ...

    • Analysis of a Cell-based Call Admission Control Scheme for QoS Support in Multimedia Wireless Networks 

      Nasser, Nidal H.; Guizani, Sghaier ( IEEE , 2007 , Conference Paper)
      Next generation wireless communication systems target to provide guaranteed quality of service (QoS) for multimedia applications. In this paper, a multiple-threshold bandwidth reservation scheme combined with a call admission ...

    • Novel cooperative policy for cognitive radio networks: Stability region and delay analysis 

      Salman, Mohamed; El-Keyi, Amr; Nafie, Mohammed; Hasna, Mazen ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      We consider a cognitive radio system that consists of primary user, secondary user, and their destinations. The secondary user has a relaying capability, i.e., it transmits the relayed packets from the primary user. Unlike ...

    • Optimized collaborative spectrum sensing in energy harvesting cognitive radio networks 

      Adeli, Mohammad Hassan; Mohammadian, Fariba; Taherpour, Abbas; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      We study the probability of error optimization problem in collaborative spectrum sensing (CSS) with limited time and energy resources in energy harvesting cognitive radio (CR) networks. The frame structures for sensing and ...

    • A predictive strategy for lifetime maximization in selective relay networks 

      Mousavifar, S.A.; Khattab, T.; Leung, C. ( IEEE , 2009 , Conference Paper)
      Two algorithms based on an energy conserving dynamic transmit power threshold are proposed for improving the lifetime in relay networks utilizing selective relay strategies with amplify-and-forward (AF) relays. the lifetime ...
