Energy efficiency has pervaded nearly every aspect of sensor network design from platforms to network stacks to applications. What has been missing is a method to empirically evaluate the energy-efficiency claims made in the literature. MoteScope is a heterogenous, energy-aware wireless sensor network testbed under development at UC Berkeley that will provide unparalleled visibility into the operation of sensor networks. This community resource will allow fine-grained instrumentation at every node in the testbed. Users will be able to monitor instantaneous and accumulated current draw across four decades of dynamic range and microsecond resolution. Nodes will be able to measure physical channel utilization automatically. We have designed the testbed architecture and implemented the energy monitoring instrumentation. We are now scaling the benchtop prototypes towards a 1,000 node testbed embedded in Soda Hall.
