Opportunistic scheduling using cognitive radio

Dans les approches cognitives traditionnelles basees sur la recherche d'interference, une bande de communication sur laquelle est detectee de l'interference est eliminee sans prendre en compte les caracteristiques temporelles de cette derniere. L'objectif de ce papier est d'alerter la communaute scientifique sur l'interet de pendre en compte les caracteristiques temporelles de l'interference. Ainsi le terminal a radio cognitive pourra gerer de facon opportuniste l'interference presente dans les reseaux. Dans ce but, une modelisation mathematique du comportement temporel de l'interference est realisee lorsque ces signaux obeissent a une loi de distribution log-normale. Dans le cas particulier d'une microcellule (hot-spots) faisant partie d'une macro cellule et communicant toutes deux sur la meme bande de frequence, des parametres cles tel que le debit sont determines.
