    • Optimization of Threshold for Energy Based Spectrum Sensing Using Differential Evolution 

      Narayanan, K. Aravind; Shivaram, P. Arun; Maheshkumar, M.; Santhoshkumar, K.; Kumar, L. Sathiesh; Kumar, L. Sathiesh; Narayanankutty, K.A (Scientific Research Publishing, 2011-07)
      Interference threshold based on energy setting in cognitive radios is a non-convex optimization problem [4]. The convergence of optimization techniques like Genetic algorithm (GA) takes several iterations to fix this ...

    • The Performance Gain of Cognitive Radio in Adaptive Modulation Scheme 

      Foukalas, Fotis (Scientific Research Publishing, 2010-07)
      Cognitive radio is considered as one of the main enablers for provisioning dynamic and flexible spectrum/channel allocation in wireless communications. The reliable data transmission over cognitive radio should employ ...

    • A Self-Optimization of the Dynamic Resource Management Based on the Cognitive Radio 

      Raiyn, Jamal (Scientific Research Publishing, 2011-04)
      This paper describes a novel self-optimized approach for resource management based on the cognitive radio in the cellular networks. The cognitive radio techniques offer several features like autonomy, sensing and negotiation. ...
