An Optimization Handover Scheme Based On HMIPv6
نویسندگان
چکیده
The process that mobile node still maintains its connectivity when moved from one access router (AR) to another access router is called handover. The handover technology is one of the most important technologies for the quality of real-time operation. In order to reduce the handover delay. Fast Mobile IPv6 (FMIPv6), Hierarchical Mobile IPv6 (HMIPv6) and Fast Hierarchical Mobile IPv6 are studied. Then, an optimization method based on HMIPv6 is advanced. On the basic of mobile anchor point (MAP), this scheme introduces the concept of regional anchor point (RAP) with the purpose of reducing the binding update messages between mobile node and home agent (HA) or correspondent node, thus lowering the handover delay.

Combined Approach for Handover Support in MIPv6
In the future generation networks mobile IP is one of the dominating protocols that provide seamless mobility support in the internet. Although Internet Engineering Task Force has standardized various mobility management protocols like MIPv6, FMIPv6, HMIPv6, FHMIPv6 but still there is space for enhancing their performance. MIPv6 suffers from drawback like handover latency & high signaling cost....

Fast Handover for Hierarchical Mobile IPv6 (F-HMIPv6) that combines advantages of Fast Handover for Mobile IPv6 (FMIPv6) and Hierarchical Mobile IPv6 (HMIPv6) achieves the superior performance in terms of handover latency and signaling overhead compared with previously developed mobility protocols. However, without being secured, F-HMIPv6 is vulnerable to various security threats. In 2007, Kang...
متن کاملA Comprehensive Study on Handover Performance of Hierarchical Mobile IPv6
Recently, IETF has standardized Mobile IPv6 (MIPv6) and Hierarchical Mobile IPv6 (HMIPv6) for supporting IPv6 mobility. Even though existing literatures have asserted that HMIPv6 generally improves MIPv6 in terms of handover speed, they do not carefully consider the details of the whole handover procedures. In this paper, based on the current IETF standards of both MIPv6 and HMIPv6, we conduct ...

---International Engineering Task Force (IETF) proposed MIPv6 and HMIPv6 both mobility management solutions to support the IP mobility. Although HMIPv6 is an extension of MIPv6 still there is handover latency and packet loss in HMIPv6.In this paper a scheme is presented that supports a fast handover efficiently in hierarchical mobile IPv6 networks (HMIPv6). In HMIPv6 when a mobile node (MN) mov...

An optimized fast vertical inter-mobility anchor point (MAP) handover scheme for Hierarchical Mobile IPv6 (HMIPv6) is proposed for heterogeneous wireless access networks. Two existing non-optimized vertical handover schemes – the simple vertical inter-MAP handover for HMIPv6 (SVH6) and fast vertical inter-MAP handover for HMIPv6 (FVH6) – assisted by existing hierarchical handover and fast hando...
