The wireless environment is unstable. The transmission link always bursts into errors, which makes the head packet fail to be transmitted. This paper gives the fact that choosing the queue with bad error link to transmit the packet will bring about the Head Of Line (HOL) problem: the blocked head packet would make the rest postpone to be sent The HOL problem occurs frequently because of the unstable...
This Letter proposes a fast selective ACK scheme for Stream Control Transmission Protocol (SCTP) to enhance transmission throughput in multi-homing scenarios. In the proposed scheme, a multi-homed receiver sends SACK chunks to the sender over the fastest reverse path, which facilitates to inflate the congestion window and to retransmit the lost data packets as quickly as possible. Simulation results...
Forward error correction (FEC) scheme has dual side-effects on the throughput performance for the satellite networks. One is to consume some extra bandwidth to send redundant information, and the other is to disable the corruption-aware TCP variants to differentiate the corruption events from the loss events. This may result in significant throughput jitter while satellite channel is in an unsteady...
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...
Generally only individual regions suffer bit errors as a packet travels a lossy channel. At the receiver side, however, the entire packet has to be discarded even if only one bit is erased. This may result in degradation of the throughput performance of stream control transmission protocol (SCTP) over wireless networks with high bit error rate. This paper proposes a dynamic partial cyclic redundancy...
