    • Cognitive Radio Networks with Probabilistic Relaying: Stable Throughput and Delay Tradeoffs 

      Ashour M.; El-Sherif A.A.; ElBatt T.; Mohamed A. ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)
      This paper studies fundamental throughput and delay tradeoffs in cognitive radio systems with cooperative secondary users. We focus on randomized cooperative policies, whereby the secondary user (SU) serves either its own ...

    • 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 ...

    • Priority-based scheduling for limited energy cognitive relaying 

      Elsaadany M.; Khattab T.; Hasna , Mazen; Abdallah M.; Khairy M. ( IEEE , 2010 , Conference Paper)
      We study the problem of cognitive relaying with limited-energy constraint in opportunistic spectrum access cognitive networks. Under this network setting, the cognitive user increases the spectrum availability for its own ...
