A High-Fidelity Sensor Network Simulator Using Accurate CC2420 Model

In sensor networks, it is useful for developers to simulate applications before actual deployment. In this paper, we report a high-fidelity instruction-level sensor network simulator using an accurate CC2420 model. This simulator is independent of the target node's operating system and it supports MICAz motes which contain Atmegal28 and CC2420. Besides its cycle-accurate processor emulation, the CC2420's internal operations are accurately modeled so that our simulator shows realistic wireless communication timing during the simulation. In addition, our simulator shows power consumption of each sensor node. Using this simulator, researchers can accurately verify the sensor network's behavior and power consumption without actual hardware deployment.
