Performance analysis of TCP with the support of seamless handover
F. Lijing, L. Chengshiduan · 2003
As mobile node takes a relatively long time to hand over and some packets are lost during these period, TCP performs badly in mobile environment. IETF present seamless handover mechanism, include fast handover and smooth handover, to reduce the delay and packet losses during handover to improve TCP performance. It is taken for granted that the performance of TCP with seamless handover is surely better than that without. However, we find that the performance of TCP especially Reno with seamless handover is worse than that without in some cases through a large number of detailed simulation. We analyze the reason inside the phenomenon and give a solution to solve it. and sometimes even degrade TCP's performance in section 3. Section 4 gives an effective solution. We draw a conclusion in section 5.
