Abstract
Conventional TCPs are designed to work efficiently on wired network where any transmission errors rarely take place. However, the probability of transmission error in a wireless network is much higher than in a wired network, due to pass loss, multipath fading, and many kinds of interference. There were many researches on preventing the degradation of TCP performance in these wireless networks with bad channel condition. One of these researches is the SNOOP protocol which is link-layer solution for achieving high throughput of TCP. However, this SNOOP protocol is apt to retransmit some TCP segments unnecessarily, which could cause some increased traffic loads in a wireless network. In this paper, we propose a new algorithm to prevent the unnecessary retransmission of TCP segments and to achieve increased performance of TCP.
