Abstract

The traditional reliable transport protocols are originally designed for the wired networks, which regard any packet loss 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 in the error-prone wireless networks. Unfortunately, the corruption-aware transport protocols cannot work in realistic networks up to now since the corrupted packets will be discarded by the link layer checksum mechanisms before they are delivered to the transport layer. This paper introduces a cross-layer adaptive partial Frame Check Sequence scheme to safely enable the corruption-aware transport protocols in the next generation wireless communications without disabling the link layer 32-bit Cyclic Redundancy Check checksum mechanisms. Simulation results show that the proposed scheme can help the corruption-aware transport protocols to significantly improve their performance compared to that of the existing schemes.
