TRMSim-WSN (Trust and Reputation Models Simulator for Wireless Sensor Networks) is a Java-based simulator aimed to test Trust and Reputation models for WSNs. It provides several Trust and Reputation models and new ones can be easily added.
Shawn is a discrete event simulator for large wireless sensor networks. It does not compete with others well-known simulators by simulating individual ISO layers and the protocols within these layers. Shawn emerged from a more algorithmic approach.
