—Due to extended IPv6 features, Mobile IPv6 protocol offers an improved mobility support for mobile users. Literature shows that the mobility issues in the next generation networks would be an important concern for researchers, developer and engineers. Mobility management with low latency and packet loss is a big challenge in inter technologies communication. In this study an optimized vertical handover scheme based on Hash function is proposed. The proposed model reduces the network layer registration time and address resolution time in vertical hand over process, thus the overall vertical handover latency is reduced. Further, the suggested model ensures unique Care off Address (CoA) for a mobile node, hence eliminates the Duplicate Address Detection time (DAD), which is one of the major contributors for latency in the previous vertical handover schemes.
