Optimizing handoff latency for mobile IPv6 based environments

The ever growing number of Internet subscribers through mobile devices has led to the requirement of better mobility management protocols. Mobile IP version 6 (MIPv6) by IETF supports IPv6 mobility by providing mobile nodes with uninterrupted Internet connectivity and services. MIPv6 provides network layer mobility but handoff from one network to another network causes handoff latency. Due to this latency some packets may be lost or delayed in transfer affecting the performance of transport layer. In this paper, we present a low-latency handoff scheme for MIPv6. The scheme requires access point to facilitate movement detection and access router to implement tentative addresses pool and neighbor cache table for faster address configuration with faster duplicate address detection. The performance analysis shows that proposed scheme provides with lower latency and packet loss as well as improved signaling cost and packet delivery cost.
