Hulumtuesit nga Universiteti i Waterloo dhe Laboratori K\u00ebrkues i Marin\u00ebs s\u00eb SHBA-s\u00eb paraqit\u00ebn rezultatet e zhvillimit t\u00eb nj\u00eb simulatori t\u00eb rrjetit Tor, i cili \u00ebsht\u00eb i krahasuesh\u00ebm me numrin e nyjeve dhe p\u00ebrdoruesve n\u00eb rrjetin kryesor Tor dhe lejon kryerjen e eksperimenteve q\u00eb i afrohen kushteve reale.
