Abstract
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 condi- tions. But still, simulations are costly in terms of required processing time and memory. New approaches like the Java- based simulator JiST/SWANS promise to provide signifcant 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. In this work, we focus on the comparability of imple- mented protocols and models in SWANS. Using the corre- sponding 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 show- ing that JiST/SWANS produces equivalent simulation re- sults as ns-2 in less time and with less memory, we support JiST/SWANS as a potential alternative.
