Toward Full-System, Cycle-Accurate Simulation of Sensor Networks

We present an accuracy and performance analysis of SimGate – a full-system simulation of the Stargate intermediate-level sensor network device. We also examine ensemble simulations using SimGate and either one or two simulated Mica2 motes using the same criteria. We find that accurate functional behavior and cycle counts (at the full device level) are achievable using SimGate alone, and in conjunction with simulated Motes. Also, the slowdown compared to realtime for these simulations is modest with respect to previously published work.
