A Unified Network and Node Level Simulation Framework for Wireless Sensor Networks [Report]

NESL Technical Report #: 2003-9-2


Abstract: Low power consumption is an essential requirement for wireless sensor networks. In many situations un-tethered wireless sensor nodes are expected to operate on non-renewable batteries for extended periods of time. To survive in such regimes, the embedded software running on the sensor nodes should strive to optimize power consumption at the node and network levels. In this paper, we present a novel simulation framework for quantifying power consumption in a unified way that also reflects the node level performance to network-wide power estimation. At the node level, our framework combines power simulator for the StrongARM processor with a radio and a sensing component. This is then integrated into SensorSim, an enhanced version of the ns-2 network simulator that also incorporates the sensing aspects required to simulate realistic sensor network scenarios. We illustrate the capabilities of our simulation framework to explore different power management schemes and interactions across the node level network layer and sensor field events using a representative example scenario.
