This paper proposes the use of TCP-Traffic differentiated model at wired-and-wireless boundary to alleviate the degradation of TCP performance and to reduce the energy expenditure. We assume that the wireless link is the bottleneck, which causes packet to be buffered at wired-cum-wireless interface buffer. This packet buffering at boundary node will cause the long delay for TCP retransmission packet and increase the energy expenditure by generating unnecessary ACK packets. These problems will be serious when the asymmetric link characteristic for wireless link is taken into account. Using ns-2 simulator, the performance of proposed algorithm is compared against those of Reno, Snoop protocol. The results of simulation experiments show that it achieves higher throughput, lower packet delay, and lower energy expenditure.
