Modeling and Simulation of Wireless Sensor Network (WSN) with SpecC and SystemC

As the complexity of systems is rapidly growing, the designers are moving towards use system level design Languages (SLDL) such as SystemC and SpecC. In this paper we use SystemC and SpecC languages for modeling and simulation of wireless sensor networks (WSN). First we start on simple ECO model and add modular sections as increases as the complexity. In the next step, we add data encryption using DES algorithm for security reasons. The future steps include modeling the idel/active/work phases for nodes and we add attenuation-transmission-power checking model for estimation power dissipation among nodes. We also include IEEE 802.15.4 protocol module and buffer insertion module. We have simulated the proposed framework with simulation of 3, 7 and 11 nodes in 3000 ms. The fidelity of simulations with SpecC and SytemC meet with 9.8% error and RMSD 4%. Our preliminary results from deployment of the functional-proven SystemC models into SystemC synthesizers, urges that it may be directly used in early stages of WSN nodes synthesis.
