Query: Reliability or Sustainability: Optimal Data Stream Estimation and
  Scheduling in Smart Water Networks   As a typical Cyber-Physical System (CPS), smart water distribution networks
require monitoring of underground water pipes with high sample rates for
precise data analysis and water network control. Due to poor underground
wireless channel quality and long-range communication requirements, high
transmission power is typically adopted to communicate high-speed sensor data
streams; posing challenges for long term sustainable monitoring. In this paper,
we develop the first sustainable water sensing system, exploiting energy
harvesting opportunities from water flows. Our system does this by scheduling
the transmission of a subset of the data streams, while other correlated
streams are estimated using auto-regressive models based on the sound-velocity
propagation of pressure signals inside water networks. To compute the optimal
scheduling policy, we formalize a stochastic optimization problem to maximize
the estimation reliability, while ensuring the system's sustainable operation
under dynamic conditions. We develop Data Transmission Scheduling (DTS), an
asymptotically optimal scheme; and FAST-DTS, a lightweight online algorithm
that can adapt to arbitrary energy and correlation dynamics. Using over 170
days of real data from our smart water system deployment and conducting
in-vitro experiments to our small-scale testbed; our evaluation demonstrates
that Fast-DTS significantly outperforms three alternatives, considering data
reliability, energy utilization, and sustainable operation.
