SimGate: Full-System, Cycle-Close Simulation of the Stargate Sensor Network Intermediate Node

Abstract

We present SimGate - a full-system simulator for the Stargate intermediate-level, resource-constrained, sensor network device. We empirically evaluate the accuracy and performance of the system in isolation as well as coupled with simulated Mica2 motes. Our system is functionally correct and achieves accurate cycle estimation (i.e. cycle-close). Moreover, the overhead of simulated execution is modest with respect to previously published work
