The Tor anonymous network has become quite popular with regular users on the\nInternet. In the Tor network, an anonymous path is created by selecting three\nrelays through which the connection is redirected. Nevertheless, as the number\nof Tor users has increased substantially in recent years, the algorithm with\nwhich the relays are selected affects the performance provided by the Tor\nnetwork. More importantly as the performance suffers, users will leave the\nnetwork, resulting in a lower anonymity set and in turn lower security provided\nby Tor network.\n In this paper, we proposed an algorithm for improving performance and\nsecurity of the Tor network, by employing a combination of different metrics in\nthe process of the path selection between the source and destination node.\nThese metrics are bandwidth and uptime of relays as node conditions and delays\nbetween the relays as a path condition. Through a number of experiments we show\nthat we could double the performance observed by end users when using the\nproposed technique as opposed to the current Tor path selection algorithm. More\nimportantly, the proposed technique only requires a software upgrade on the\nclient side, and other Tor nodes do not need to be modified.\n
