Query: Resource Allocation for Machine-to-Machine Communications with Unmanned
  Aerial Vehicles   In this paper, a novel framework for power-efficient, cluster-based
machine-to-machine (M2M) communications is proposed. In the studied model, a
number of unmanned aerial vehicles (UAVs) are used as aerial base stations to
collect data from the cluster heads (CHs) of a set of M2M clusters. To minimize
the CHs' transmit power while satisfying the rate requirements of M2M devices,
an optimal scheduling and resource allocation mechanism for CH-UAV
communications is proposed. First, using the queue rate stability concept, the
minimum number of UAVs as well as the dwelling time that each UAV must spend
for servicing the CHs are computed. Next, the optimal resource allocation for
the CH-UAV communication links is determined such that M2M devices rate
requirements are satisfied with a minimum transmit power. Simulation results
show that, as the packet transmission probability of machines increases, the
minimum number of UAVs required to guarantee the queue rate stability of CHs
will also significantly increase. Our results also show that, compared to a
case with pre-deployed terrestrial base stations, the average transmit power of
CHs will decrease by 68% when UAVs are used.
