  In contrast with existing works which rely on the same type of
energy-efficiency measure to design distributed power control policies, the
present work takes into account the presence of a finite packet buffer at the
transmitter side and the impact of transport protocols. This approach is
relevant when the transmitters have a non-zero energy cost even when the
radiated power is zero. A generalized energy-efficiency performance metric
integrating these features is constructed under two different scenarios in
terms of transport layer protocols characterized by a constant or an adaptive
packet arrival rate. The derived performance metric is shown to have several
attractive properties in both scenarios, which ensures convergence of the used
distributed power control algorithm to a unique point. This point is the Nash
equilibrium of a game for which the equilibrium analysis is conducted. Although
the equilibrium analysis methodology is not new in itself, conducting it
requires several non-trivial proofs, including the proof of quasi-concavity of
the payoff functions. A thorough numerical analysis is provided to illustrate
the effects of the proposed approach, and provides several valuable insights in
terms of designing interference management policies.
