In this paper, we propose a cross-layer design combining
adaptive modulation coding (AMC) and automatic repeat request (ARQ) to minimize
the bit energy consumption under both packet loss rate and retransmission delay
constraints. We analyze the best constellation size of M-ary square quadrature
amplitude modulation (MQAM) in different distance, and give advice on
retransmission limits under different packet loss rates. The impacts of path
loss fading and additive white Gaussian noise (AWGN)are taken into
consideration. The computation of energy consumption includes the circuit,
transmission and retransmission energies at both transmitter and receiver
sides. Numerical results are obtained to verify the validity of our design. We
also show that the retransmission benefit varies with the packet loss rate
