Deemah Tashman<\/strong>chercheuse postdoctorale \u00e0 Polytechnique Montr\u00e9al et membre du Lincs lab<\/strong>, a publi\u00e9 un article dans la prestigieuse revue\u00a0IEEE Transactions on Cognitive Communications and Networking,<\/strong> une revue dot\u00e9e d'un facteur d'impact impressionnant de 7,4.<\/p>

L'article, intitul\u00e9 \"Maximizing Reliability in Overlay Radio Networks With Time Switching and Power Splitting Energy Harvesting\u201d<\/strong><\/a>, est le fruit d'un effort de collaboration avec\u00a0Prof. Soumaya Cherkaoui<\/a>\u00a0et\u00a0Prof. Walaa Hamouda<\/a>.\u00a0<\/p>

Cette recherche investigue les d\u00e9fis critiques li\u00e9s \u00e0 l'optimisation de la fiabilit\u00e9 du syst\u00e8me et \u00e0 l'am\u00e9lioration de l'efficacit\u00e9 \u00e9nerg\u00e9tique au sein des r\u00e9seaux radio cognitifs (CRN) superpos\u00e9s.<\/p>

L'article a pris en consid\u00e9ration des utilisateurs secondaires (US) dispers\u00e9s al\u00e9atoirement servant de relais pour les utilisateurs primaires (UP). L'aspect cl\u00e9 est de d\u00e9signer l'un des US pour r\u00e9colter de l'\u00e9nergie via le protocole de r\u00e9colte d'\u00e9nergie par commutation temporelle (EH).<\/p>

De plus, ce relais d\u00e9sign\u00e9 utilise une strat\u00e9gie d'amplification-et-renvoi (AF) pour transmettre les messages de l'UP, les diffusant avec ses propres signaux \u00e0 travers des canaux \u00e0 \u00e9vanouissement en cascade \u03ba\u2212\u03bc.<\/p>

Pour am\u00e9liorer la collecte d'\u00e9nergie, les r\u00e9cepteurs US et UP utilisent tous deux un protocole EH \u00e0 division de puissance<\/strong> pour leurs dispositifs de stockage.<\/p>

En outre, les \u00e9metteurs US et le r\u00e9cepteur US sont d\u00e9ploy\u00e9s avec de multiples antennes pour la r\u00e9ception et appliquent l'approche de combinaison \u00e0 rapport maximal.<\/p>

Dans l'\u00e9tude, la fiabilit\u00e9 du r\u00e9seau est \u00e9valu\u00e9e \u00e0 l'aide de la probabilit\u00e9 de coupure.<\/p>

Ensuite, une \u00e9valuation de l'efficacit\u00e9 \u00e9nerg\u00e9tique est r\u00e9alis\u00e9e pour d\u00e9terminer l'efficacit\u00e9 de l'EH sur le syst\u00e8me.\u00a0<\/p>

Enfin, l'article pr\u00e9sente un probl\u00e8me d'optimisation visant \u00e0 maximiser le d\u00e9bit de donn\u00e9es des US<\/strong> en optimisant les param\u00e8tres de commutation temporelle et d'allocation de puissance du relais US.<\/p>
