Implementation Parallel Duplicate Address Detection (PDAD) mechanism for macro handover on HMIPv6

The ever growing number of mobile devices for internet communication has led to developing Mobile IPv6 (MIPv6) and all of its extentions such as Hierarchical Mobile IPv6 (HMIPv6) that has been introduced for reducing latency and data loss in micro or local handover with employs Mobilty Anchor Point (MAP). But, the problems still occur for macro handover or inter-MAP handover. In this paper we purpose to implement Parallel Duplicate Address Detection (PDAD) on HMIPv6 to reduce latency within macro handover process.
