Abstract :
Several handover schemes, such as smooth handover and fast handover, have been proposed to realize seamless handovers in mobile environment. However in our simulation, even if smooth handover in mobile IPv6 are implemented, TCP can not always be ensured to achieve better performance due to packets forwarding burst. Based on the performance analysis of TCP with the support of smooth handover, this paper proposes an enhanced buffer forwarding control scheme in smooth handover to improve TCP performance. In our scheme, a packet-pair probing technology is adopted to estimate the bandwidth of the new path from previous router (Prtr) to mobile node (MN), which is used by Prtr to control the buffered packets forwarding. Finally, simulation results demonstrate that smooth handover with our scheme can achieve better TCP performance than that without it.
