MiXiM: Mixnet Design Decisions and Empirical Evaluation

ABSTRACTIn this paper we present MiXiM, a simulation framework for mixnets that allows researchers to evaluate different design options and their tradeoffs. This framework is flexible and allows to quickly run experiments to assess combinations of mixnet building blocks, such as mixing strategies and network topologies, as well as study the effect of different parameters related to each component. The framework provides results for a number of metrics including anonymity, end-to-end latency and traffic overhead.
