Assange sought refuge at the embassy in June after losing a court battle to avoid extradition to Sweden, where is wanted for questioning about allegations of sexual assault. He denied the allegations and says the legal moves make up a ruse to get him extradited to the United States.
Although risking arrest if he sets foot outside the embassy, Assange said in an interview with CNN: "It's a little like living in a space station because there's no natural light and you've got to make all your own stuff. You can't go out to shops and so on.
"But I have been in solitary confinement. I know what life is like for prisoners. It (his current situation) is a lot better than it is for prisoners."
Assange added the standoff could end if the United States ends its investigation of WikiLeaks, a website noted for posting classified military and U.S. State Department documents.
