Alchemist

Alchemist is an extensible "meta-simulator", inspired by stochastic chemistry and tailored to pervasive computing and distributed systems. It provides a flexible meta-model, on which the developers should bind their own abstractions, realizing a so-called "incarnation". Incarnations for SAPERE and Protelis are already available and integrated in the main distribution.

All the information about it is available on the official website.
