Il est difficile de servir les utilisateurs mobiles dans un MANET (Mobile Ad-hoc Network) dense en sélectionnant l'infrastructure traditionnelle des réseaux Ad-hoc. Le multimédia mobile dans des environnements omniprésents cible souvent les réseaux mobiles ad hoc dynamiques (MANETS) avec des zones d'intérêt densément peuplées. Dans ce projet, nous avons proposé une nouvelle technologie basée sur les relais pour passer de l'ancien noeud relais au nouveau noeud relais. À cette fin, nous utilisons l'implémentation de noeuds mobiles ad hoc avec canal radio dans la plate-forme Matlab par données multimédia, c'est-à -dire Image. Nous avons simulé ce scénario avec RSSI (Received Signal Strength Indication) et PSNR (Peak to Signal Noise Ratio) en considérant plus de 15 noeuds mobiles. Sur la base des valeurs RSSI et PSNR, nous avons décidé du seuil de transfert vers le nouveau noeud relais depuis l'ancien noeud relais. De cette façon, nous avons économisé la bande passante et le spectre et avons remarqué une augmentation du débit de données multimédia avec moins de congestion du réseau.
