For the evaluation of ad hoc network protocols, researchers traditionally use simulations because they easily allow for a large number of nodes and reproducible environment conditions. But still, simulations are costly in terms of required processing time and memory. New approaches like the Javabased simulator JiST/SWANS promise to provide significant performance advantages compared to existing, well-known network simulators like ns-2. Though its creators have done comparison studies regarding processing time and memory requirements of JiST/SWANS, they did not test the validity of the results produced by the SWANS stack as well as its performance in detail.#R##N##R##N#In this work, we focus on the comparability of implemented protocols and models in SWANS. Using the corresponding counterparts both in SWANS and ns-2, with an identical set of parameters, we are able to produce results and compare them afterward. In addition, we also provide a performance analysis using these simulations. By showing that JiST/SWANS produces equivalent simulation results as ns-2 in less time and with less memory, we support JiST/SWANS as a potential alternative.
