QoS-Satisfied Pathover Scheme in FMIPv6 Environment

Using the application of bluck data transfer, we investigate the performance of QoS-satisfied pathover for transport layer mobility scheme such as mSCTP in FMIPv6 envirmonment. We find that existing scheme has some defects in aspect of pathover and throughput. Based on this, we make a potential change to mSCTP by adding QoS-Measurement-Chunk, which is used to take into account information about wireless link condition in reselection/handover process of FMIPv6 network, we proposed a scheme with an algorithm named congestion-oriented pathover (COPO) to detect congestion of the primary path using back-to-back RTTs and adapt change of the wireless link parameters. A demonstrate using simulation is provided showing how the proposed scheme provides better performance to pathover and throughput.
