A New Mechanism in Hmipv6 to Improve Micro and Macro Mobility
نویسنده
چکیده
The paper proposes new mechanism in Hierarchical Mobile IPv6 (HMIPv6) implementation for utilization in IPv6 Enterprise Gateway. This mechanism provides seamless mobility and fast handover of a mobile node in HMIPv6 networks. Besides it provides continuous communication among a member of HMIPv6 components while roaming. The mechanism anticipates future movement of mobile node and accordingly provides an effective updating mechanism. A bitmap has been proposed to help in applying the new mechanism as will be explained throughout this paper. Instead of scanning the prefix bits which might be up to 64 bits for subnet discovery, about 10% of this length will be sufficient to determine the hierarchical topology. This will enable fast Micro and Macro HMIPv6 in Enterprise Gateway.

Macro/micro-mobility fast handover in hierarchical mobile IPv6
Mobile Internet Protocol version 6 (MIPv6) has been proposed to solve the problem of mobility in the new era of Internet by handling routing of IPv6 packets to mobile nodes that have moved away from their home network. Users will move frequently between networks, as they stay connected to the Internet. Thus, as mobility increases across networks, handovers will significantly impact the quality ...

Future internet works will include large numbers of portable devices moving among small, wireless cells. In order to support real-time applications, users demand seamless mobility and Quality-of-Service (QoS) provisioning. The handover technology is one of the most important technologies for the quality of real-time operation which guarantee the QoS of mobile Internet. Mobility management issue...
متن کاملA Fast Handover Protocol for Mobile IPv6 Using Mobility Prediction Mechanism
Mobile IPv6 enables mobile node to roam transparently in any network. It shows good performance for macro mobility but it is not proper for supporting micro mobility because of large latency. Accordingly, IETF (Internet Engineering Task Force) mobileip WG(Working Group) suggests Fast Handover Protocol and HMIPv6(Hierarchical Mobile IPv6) for micro mobility management. However, HMIPv6 has some p...
متن کاملES-FHMIPv6: An Efficient Scheme for Fast Handover over HMIPv6 Networks
The Hierarchical Mobile IPv6 (HMIPv6) has been proposed by IETF to reduce registration control signaling. It separates micro-mobility from macro-mobility with the help of an intermediate mobility agent, called the mobility anchor point (MAP), and exploits a Mobile Node’s (MN’s) spatial locality. However, in HMIPv6, the handover process reveals numerous problems manifested by the latency in conf...
متن کاملExperimental Evaluation of Mobility Anchor Point Selection Scheme in Hierarchical Mobile IPv6
Hierarchical Mobile IPv6 (HMIPv6) was designed to support IP micro-mobility management in the Next Generation Networks (NGN) framework. The main design behind this protocol is the usage of Mobility Anchor Point (MAP) located at any level router of network to support hierarchical mobility management. However, the distance MAP selection in HMIPv6 causes MAP overloaded and increase frequent bindin...
