Optimizing Anonymity and Efficiency: A Critical Review of Path Selection Strategies in Tor
The Onion Router (Tor) relies on path selection algorithms to balance performance and anonymity by determining how traffic flows through its relay network. As Tor scales and usage patterns evolve, default strategies such as bandwidth-weighted random selection and persistent guard nodes face increasing performance limitations. This study presents a comparative evaluation of five path selection strategies: Random, Guard, Congestion-Aware, and two Geographic approaches (Diversity Driven and Latenc…
