Optimization of Qos Parameters in Cognitive Radio Using Adaptive Genetic Algorithm
Genetic algorithm based optimization rely on explicit relationships between parameters, observations and criteria. GA based optimization when done in cognitive radio can provide a criteria to accommodate the secondary users in best possible space in the spectrum by interacting with the dynamic radio environment at real time. In this paper we have proposed adaptive genetic algorithm with adaptin...
متن کاملOptimization of Spectrum Sensing Parameters in Cognitive Radio Using Adaptive Genetic Algorithm
Quality of service parameters of cognitive radio, like, bandwidth, throughput and spectral efficiency are optimized using adaptive and demand based genetic algorithm. Simulation results show that the proposed method gives better real life solution to the cognitive radio network than other known approach. Keywords—adaptive genetic algorithm, bandwidth, cognitive radio, spectrum sensing, throughput.
متن کاملPerformance Evaluation of Qos Parameters in Cognitive Radio Using Genetic Algorithm
The efficient use of available licensed spectrum is becoming more and more critical with increasing demand and usage of the radio spectrum. This paper shows how the use of spectrum as well as dynamic spectrum management can be effectively managed and spectrum allocation schemes in the wireless communication systems be implemented and used, in future. This paper would be an attempt towards bette...
متن کاملOptimization of Cognitive Radio Sensing Techniques Using Genetic Algorithm
Cognitive radio technology is a low cost communication system. The main reason of choosing the cognitive system is that it prevents the interfering of licensed and authorised users; by choosing the available frequencies and waveforms automatically Today the development of the new radio technologies is limited because of the available radio spectrum. But the spectrum sensing is the vital technol...
متن کاملA Review on QOS Parameters in Cognitive Radio Using Optimization Techniques
Cognitive radio (CR) is an advanced technology in wireless communicationsystems, which allows the use of frequency spectrum efficiently. Proper utilization of frequency spectrum is possible by using dynamic spectrum allocation. The progress of the radio spectrum depends on how efficiently these resources or spectrum are allocated. The CR users or the secondary users are allocated with the unuse...
