چکیده
New generation networks, based on Cognitive Radio technology, allow dynamic allocation of the spectrum, alleviating spectrum scarcity. These networks also have a resilient potential for operation energy saving. In this paper, we present novel wireless network optimization algorithm cognitive radio cloud sharing-decision mechanism. Three Key Performance Indicators (KPIs) were optimized: usage, power consumption, and exposure. For realistic suburban scenario in Ghent city, Belgium, determine optimal trade-off between KPIs. Compared to traditional design, our cloud-based architecture reduced consumption by 27.5%, average global exposure 34.3%, usage 34.5% at same time. Even worst-case (worst achieved result single KPI), solution performs better than 4.8% terms 7.3% 4.3%

Multi-objective Grasshopper Optimization Algorithm based Reconfiguration of Distribution Networks
Network reconfiguration is a nonlinear optimization procedure which calculates a radial structure to optimize the power losses and improve the network reliability index while meeting practical constraints. In this paper, a multi-objective framework is proposed for optimal network reconfiguration with the objective functions of minimization of power losses and improvement of reliability index. T...
متن کاملSensing Optimization in Cooperative Cognitive Radio Networks
Cooperative spectrum sensing is a key function in cognitive radio networks in order to provide unused spectrum access opportunities and mitigate the impact of interference to the primary networks. Cooperative sensing can incur additional cooperation overhead, increased energy consumption, extra sensing time and delay in heterogeneous networks. In this paper, the sensing time period is optimized...

Abstract—Cooperative spectrum sensing is a crucial challenge in cognitive radio networks. Cooperative sensing can increase the reliability of spectrum hole detection, optimize sensing time and reduce delay in cooperative networks. In this paper, an efficient central capacity optimization algorithm is proposed to minimize cooperative sensing time in a homogenous sensor network using OR decision ...
