Query: Impact of Node Speed on Throughput of Energy-Constrained Mobile Networks
  with Wireless Power Transfer   A wireless charging station (WCS) transfers energy wirelessly to mobile nodes
within its charging region. This paper investigates the impact of node speed on
the throughput of WCS overlaid mobile networks when packet transmissions are
constrained by the energy status of each node. The energy provision for each
node depends on its moving speed. A slow-moving node outside the charging
region is unable to receive energy from WCSs for a long time, while one inside
the charging region consistently recharges the battery. Reflecting on these
phenomena, we design a two-dimensional Markov chain, where the states
respectively represent the remaining energy and the distance to the nearest
WCS. Solving this enables the following theoretic insights. Firstly, the
throughput is a non-decreasing function of node speed. With faster node speed,
the throughput converges to that of the independent and identically distributed
(i.i.d.) mobility model where nodes can move anywhere without being restricted
by their previous positions. Secondly, if the battery capacity of each node is
infinite, the throughput is equivalent to that of the i.i.d. mobility model
regardless of node speed. Finally, the throughput scaling is calculated as
Theta(min(1, m/n)c^{\min(1,m/n))), where n and m represent the number of nodes
and WCSs, respectively.
