VisualSim Wireless is a modeling and simulation framework for wireless and sensor networks that builds on and leverages VisualSim. Modeling of wireless networks require sophisticated modeling of communication channels, sensors, ad-hoc networking protocols, localization strategies, media access control protocols, energy consumption in sensor nodes, etc. This modeling framework is designed to support a component-based construction of such models. It supports actor-oriented definition of network nodes, wireless communication channels, physical media such as acoustic channels, and wired subsystems. The software architecture consists of a set of base classes for defining channels and sensor nodes, a library of subclasses that provide certain specific channel models and node models, and an extensible visualization framework. Custom nodes can be defined by sub-classing the base classes and defining the behavior in Java/C/C++ or by creating composite models using any of several VisualSim modeling libraries. Custom channels can be defined by sub-classing the WirelessChannel base class and by attaching functionality defined in VisualSim models. It is intended to build models that include sophisticated elements from several aspects.

The basic components of this framework are the simulator, the channel model and the sensor node model, and explains how to build sensor network models graphically. The demonstration provides tutorials that will enable the reader to construct elaborate sensor network models and to have confidence in the results of a simulation of those models. VisualSim Wireless Library can be used to construct models of such systems. VisualSim Wireless is built on top of VisualSim, a framework supporting the construction of such domain-specific tools.
