A Self-Optimization of the Dynamic Resource Management Based on the Cognitive Radio
(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. ...
Optimization of Threshold for Energy Based Spectrum Sensing Using Differential Evolution
(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 ...
