Query: Relay Selection & Power Allocation for Maximizing Sum-Throughput of a
  Buffered Relay Network   Considering two-hop cooperative communication with buffered half-duplex
relays, this work jointly optimizes relay selection and transmit power at the
relay to maximize the sum-throughput of the network subject to a minimum
throughput requirement of each hop and transmit power constraint. The
optimization problem is solved and two new buffer aware selection schemes,
namely joint relay power allocation and selection scheme (JPASS) and ratio
selection scheme (RSS) are proposed. Numerical results show that the average
sum-throughput of both the proposed schemes is up to 40% higher compared to the
existing schemes in the literature.
