Query: Structural Properties of Optimal Transmission Policies for
  Delay-Sensitive Energy Harvesting Wireless Sensors   We consider an energy harvesting sensor transmitting latency-sensitive data
over a fading channel. We aim to find the optimal transmission scheduling
policy that minimizes the packet queuing delay given the available harvested
energy. We formulate the problem as a Markov decision process (MDP) over a
state-space spanned by the transmitter's buffer, battery, and channel states,
and analyze the structural properties of the resulting optimal value function,
which quantifies the long-run performance of the optimal scheduling policy. We
show that the optimal value function (i) is non-decreasing and has increasing
differences in the queue backlog; (ii) is non-increasing and has increasing
differences in the battery state; and (iii) is submodular in the buffer and
battery states. Our numerical results confirm these properties and demonstrate
that the optimal scheduling policy outperforms a so-called greedy policy in
terms of sensor outages, buffer overflows, energy efficiency, and queuing
delay.
