초록
The traditional reliable transport protocols are originally designed for the wired networks, which regard any packet losses as the indication of network congestion and halve their congestion windows to alleviate the traffic overload of network. However, unlike in wired networks, non-congestion losses will severely degrade the performance of traditional transport protocols in wireless networks. Thus some corruption-aware transport protocols have been proposed to overcome the performance degradation caused by corruption. Unfortunately, the corruption-aware transport protocols cannot work in realistic networks up to now since the corrupted packets have been discarded by the link layer checksum mechanisms before they are delivered to transport layer. This paper proposes a technique to overcome this problem without disabling the link layer checksum mechanisms. Simulation results show that the performance of corruption-aware transport protocols are still far better than that of traditional ones while the proposed scheme is applied.
Abstract
The traditional reliable transport protocols are originally designed for the wired networks, which regard any packet losses as the indication of network congestion and halve their congestion windows to alleviate the traffic overload of network.

Thus some corruption-aware transport protocols have been proposed to overcome the performance degradation caused by corruption. Unfortunately, the corruption-aware transport protocols cannot work in realistic networks up to now since the corrupted packets have been discarded by the link layer checksum mechanisms before they are delivered to transport layer. This paper proposes a technique to overcome this problem without disabling the link layer checksum mechanisms. Simulation results show that the performance of corruption-aware transport protocols are still far better than that of traditional ones while the proposed scheme is applied.
