Query: Optimized Random Deployment of Energy Harvesting Sensors for Field
  Reconstruction in Analog and Digital Forwarding Systems   This work examines the large-scale deployment of energy harvesting sensors
for the purpose of sensing and reconstruction of a spatially correlated
Gaussian random field. The sensors are powered solely by energy harvested from
the environment and are deployed randomly according to a spatially
nonhomogeneous Poisson point process whose density depends on the energy
arrival statistics at different locations. Random deployment is suitable for
applications that require deployment over a wide and/or hostile area. During an
observation period, each sensor takes a local sample of the random field and
reports the data to the closest data-gathering node if sufficient energy is
available for transmission. The realization of the random field is then
reconstructed at the fusion center based on the reported sensor measurements.
For the purpose of field reconstruction, the sensors should, on the one hand,
be more spread out over the field to gather more informative samples, but
should, on the other hand, be more concentrated at locations with high energy
arrival rates or large channel gains toward the closest data-gathering node.
This tradeoff is exploited in the optimization of the random sensor deployment
in both analog and digital forwarding systems. More specifically, given the
statistics of the energy arrival at different locations and a constraint on the
average number of sensors, the spatially-dependent sensor density and the
energy-aware transmission policy at the sensors are determined for both cases
by minimizing an upper bound on the average mean-square reconstruction error.
The efficacy of the proposed schemes are demonstrated through numerical
simulations.
