ViridiScope: design and implementation of a fine grained power monitoring system for homes
TL;DR: ViridiScope is a fine-grained power monitoring system that furnishes users with an economical, self-calibrating tool that provides power consumption of virtually every appliance in the home and can estimate the end-point power consumption within 10% error.
Proceedings ArticleDOI
NAWMS: nonintrusive autonomous water monitoring system
TL;DR: An adaptive auto-calibration procedure is devised, which attempts to solve a two phase linear programming and mixed linear geometric programming problem and shows an accuracy, over likely domestic flow-rate scenarios, with long-term stability and a mean absolute error of 7%.
Journal ArticleDOI
Temperature Compensated Time Synchronization
TL;DR: TCTS exploits the on-board temperature sensor existing in many sensor network platforms and uses this temperature sensor to autonomously calibrate the local oscillator and removes effects of environmental temperature changes, which allows a time synchronization protocol to increase its resynchronization period, without loosing synchronization accuracy, and thus saves energy and communication overhead.

Compressive Oversampling for Robust Data Transmission in Sensor Networks

TL;DR: It is shown that CS erasure encoding (CSEC) with random sampling is efficient for handling missing data in erasure channels, paralleling the performance of BCH codes, with the added benefit of graceful degradation of the reconstruction error even when the amount of missing data far exceeds the designed redundancy.
Journal ArticleDOI
On the interaction of clocks, power, and synchronization in duty-cycled embedded sensor nodes
TL;DR: This work investigates the impact of the clocking subsystem on the time synchronization service and address, in particular, the influence of changes in environmental temperature on clock drift in highly duty-cycled wireless sensor nodes.
