Implementing aggressive pathover with aware mSCTP extension in FMIPv6 networks

The Fast mobile IPv6 network (FMIPv6) should support guaranteed QoS for a large-scale real-time multimedia transmission and mobility, but exiting transport layer mobility scheme such as mSCTP has some defect 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. In this paper, we also proposed an algorithm named congestion-oriented pathover (COP) to detect congestion of the primary path using back-to-back RTTs. Therefore, the proposed scheme with congestion-oriented pathover (COP) is more robust to 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, and further to guaranteed QoS. Correspondingly, the proposed scheme outperforms previous improvement and current mSCTP.
