IMPROVING HANDOVER MECHANISM OF MOBILE IPV6 - ENHANCING HANDOVER PERFORMANCE

Abstract

Handover latency of Mobile iPv6 greatly influences the network performance; resulting in hardly meeting the requirements of real-time applications. Some mechanisms to improve the handover of Mobile iPv6 has been proposed and become the standard such as Fast  handover for Mobile  iPv6,  hierarchical Mobile iPv6 in order to minimize latency resulted by handover. However, the latency of the improved handover mechanisms which have been proposed for Mobile iPv6 still remains large and should be further studied to find more effective handover mechanisms.  We propose a mechanism to improve handover of Mobile iPv6. In the proposed mechanism of handover, MN will perform a new  coa and send the binding update message to the ha and cns before the handover actually occurs. IMiPv6 handover mechanism reduced significantly its delay in comparison to the handover mechanisms for Mobile iPv6 which have been proposed and the package loss may  be minimized  to 0.
