An Approach for the Corruption-Aware Protocols to Work over Link Layer CRC Mechanisms

Unlike in wired networks, non-congestion losses will result in significant performance degradation in wireless networks. Thus some corruption-aware transport protocols have been presented to focus on the packet loss 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 corruption-aware transport protocol can still behave far better than the traditional transport protocol while the proposed scheme is applied.
