We investigate the throughput-energy efficiency performance of TCP Tahoe and Reno on wireless links using a FEC/ARQ protocol at the link layer. The effect of the link layer (LL) parameters like the LL packet size, number of LL retransmission attempts, and FEC code rate on the TCP performance is evaluated. It is shown that the retransmissions at the link layer must persist long enough to outlast the average bad state duration of the multipath Rayleigh fading process in order to achieve throughput performance better than TCP without ARQ at the link layer. We also evaluate the energy consumption performance of TCP Tahoe and Reno with and without LL FEC/ARQ by defining energy efficiency as the average number of successful TCP packet transmissions per unit energy consumed. It is shown that without LL ARQ, using TCP Reno instead of TCP Tahoe leads to some degradation in throughput and a much more significant degradation in energy efficiency. However, with a suitable LL ARQ in place, TCP Reno performs as go
