Title (EN) COGNITIVE RADIO ENGINE APPLICATION OF GENETIC ALGORITHMS
(FR) MOTEUR RADIO COGNITIF FONDE SUR DES ALGORITHMES GENETIQUES DANS UN RESEAU
Abstract:
(EN) A genetic algorithm (GA) approach is used to adapt a wireless radio to a changing environment. A cognitive radio engine (34) implements three algorithms; a wireless channel genetic algorithm (WCGA-341), a cognitive system monitor (CSM-342) and a wireless system genetic algorithm (WSGA-434). A chaotic search and controllable boundaries allows the cognitive radio engine (34) to seek out and discover unique solutions efficiently. By being able to control the search space by limiting the number of generations, crossover rates, mutation rates, fitness evaluations, etc., the cognitive system can ensure legal and regulatory compliance as well as efficient searches. The versatility of the cognitive process can be applied to any adaptive radio (32). The cognitive system defines the radio chromosome, where each gene represents a radio parameter such as transmit power, frequency, modulation, etc. The adaptation process of the WSGA (343) is performed on the chromosomes to develop new values for each gene, which is then used to adapt the radio settings (32).
(FR) L'invention porte sur une approche d'algorithme génétique (GA) permettant d'adapter une radio sans fil à un environnement changeant. Un moteur radio cognitif met en place trois algorithmes : un algorithme génétique de canal sans fil (WCGA), un moniteur de système cognitif (CSM) et un algorithme génétique de système sans fil (WSGA). Une recherche chaotique comprenant des limites contrôlables permet au moteur radio cognitif de chercher et découvrir de manière efficace des solutions uniques. Du fait de sa capacité à contrôler l'espace de recherche par limitation du nombre de générations, de taux critiques, de taux de mutation, d'évaluations de santé physique, etc., le système cognitif peut assurer une conformité légale et réglementaire ainsi que des recherches efficaces. La versatilité du procédé cognitif peut être appliquée sur n'importe quelle radio adaptative. Le système cognitif définit le chromosome radio, chaque gène représentant un paramètre radio tel qu'une puissance de transmission, une fréquence, une modulation, etc. Le procédé d'adaptation de WSGA est appliqué sur les chromosomes afin de développer de nouvelles valeurs pour chaque gène, et sert ensuite à adapter le réglage radio.
