It is well-known that the spurious fast retransmission and timeout widely exist in the course of vertical handover when a mobile node (MN) moves from a longer transmission delay network into a shorter one. Some solutions for the problems have been discussed in a lot of literatures for non-Cognitive Radio (non-CR) scenarios. One of them, bicasting is the main method to improve the transmission performance...
In the existing SCTP, an association is established by exchanging four initial chunks during four-way handshakes. What is serious is that the association establishment phase has to be backed off exponentially once any initial chunk gets lost or suffers random bit errors. This will result in a severe performance degradation of SCTP over wireless networks due to a very long waiting time. In order to...
Up to now, the most concurrent multi-path transport (CMT) schemes mainly aim at the issues caused by forward transmission like data reordering at receiver side and neglect the studies on impact of reverse paths' transmission delays. This paper proposes a SACK scheduling mechanism for the CMT schemes to accelerate data transmission in multi-homing environment, in this scheme, the most SACK chunks will...
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...
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...
