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. In this paper, a WSN （wireless sensors network） emulator, implemented on a FPGA, is described by： describing some models as examples, how multiple simulations can be done when the device was configured and programmed once, and how results from the behavioral emulator can be extracted. The diversity of applications and the typically scarce node resources set very tight constraints to WSN. It is not possible to fulfill all requirements with a general purpose WSN, for which reason the rapid development of application specific WSNs is preferred. A new emulator for the design, simulation, and evaluation of WSNs, implemented on a very dense FPGA （field programmable gate arrays）, is presented, exploring the parallelism and his resources to do a very rapid simulation ofa WSN for long periods, and without overloading memory by the intermediate data.

Channel Transmission Behavioral Modeling Dedicated to WSNs

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, the authors briefly describe the behavioral models of the elements of a large scale WSN （wireless sensors network） used to create simulator, focusing specifically on the model of the transmission channel, and how it can retrieve results from the behavioral simulator. In side to legacy network simulator, for the testing and modeling of communication protocols, this simulator should not omit WSN specific aspect, in accuracy it covers the modeling of node platforms, protocols, and real world phenomena.
