Realistic simulation for tiny batteryless sensors

Abstract

Battery-free sensing promises to revolutionize the scientific and industrial communities by enabling long term, maintenance free deployments in tough to reach places. However, developing applications for these intermittently-powered, batteryless devices is notoriously demanding. Each device's performance is closely tied to its environment at runtime, and developers are often unable to predict how their sys-Tem will be behave upon deployment. In this paper we present an instruction level simulator based off of MSPsim for intermittently-powered devices that can accurately emulate real-world energy harvesting conditions, taking into account power models of common hardware peripherals like a radio, and accelerometer. These harvester conditions are represented by IV surfaces recorded by the Ekho hardware emulator We have provided this simulator as an open source tool for the benefit of the community.
