Improving TCP performance over mobile IPv6

Abstract

In mobile and wireless networks, bit errors and handoffs cause packet losses. TCP applications in mobile and wireless networks experience severe performance degradation because packet losses initiate congestion control mechanism. In this paper we assume a mobile IPv6 environment and propose methods to avoid unnecessary invocation of TCP congestion control and, therefore, improve TCP performance. We propose to improve the mobile IPv6 handoff protocol and modify the Snoop protocol enabling it to handle handoffs. We show the effectiveness of the proposed method through simulation. © Springer-Verlag 2004.
