History based Handover Broker Scheme for SCTP

Abstract

This paper presents history based broker handover scheme for SCTP (stream control transmission protocol) in order to minimize the handover latency by the ping pong behavior of mobile node. SCTP is alternate protocol to TCP in the transport layer. It has multi-homing feature which provides the mobile node with dual interfaces to minimize the packet loss during handover in the overlapped region. L4 handover scheme using the multi-homing of SCTP is well known to reduce the latency more than handover schemes using other protocols. This paper presents an efficient handover scheme for IPv6 and IPv4 by utilizing the visiting history of MN (mobile node) and the broker instead of the CN (correspondent node). The considerations to implement this scheme in the real environment are also discussed.
