Transmission channel behavioral model for a wireless sensors network simulator

The design, manufacture and deployment of embedded systems become increasingly complex and multidisciplinary process. Before the steps of manufacturing and deployment, a simulation and validation phase is necessary. Given the increasing complexity of systems such as telecommunications systems, control systems and others, a specific simulation and validation process must take place. This simulation ideally made in a single development environment, should cover different areas and all components of the system. In this paper, we briefly describe the behavioral models of the elements of a large scale wireless sensors network (WSN) used to create our simulator, focusing specifically on the model of the transmission channel, and how we can retrieve results from the behavioral simulator. In side to legacy network simulator, for the testing and modeling of communication protocols, this simulator shouldn´t omit WSN specific aspect, in accuracy it covers the modeling of node platforms, protocols, and real world phenomena.
