DMAP-FR: Dynamic Mobility Anchor Points for Mobility, Service and Failure Recovery Management in Mobile IPv6 Systems
نویسندگان
چکیده
In this paper, we propose and analyze DMAP-FR, a mobility and service management scheme with failure recovery (FR) control in Mobile IPv6 systems. The basic idea behind DMAP-FR is to leverage access routers (ARs) running as regional mobility anchor points (MAPs) as in Hierarchical Mobile IPv6 (HMIPv6) for mobility and service management formobile nodes (MNs). However, unlikeHMIPv6,DMAP-FR allows theMAP of each MN to be determined dynamically based on the mobility and service characteristics of the MN and the failure behavior of ARs with the goal to minimize the network traffic. DMAP-FR incorporates fault tolerance mechanisms to allow the system to quickly recover from AR and MAP failures. We identify the best dynamic regional area size for the selection of MAP for each MN such that the overall network traffic due to servicing mobility, service and fault tolerance related operations is minimized. We demonstrate that DMAP-FR outperforms HMIPv6 for the same AR failure rate.

We propose and analyze a cross-layer integrated mobility and service management scheme called DMAPwSR in Mobile IPv6 environments with the goal to minimize the overall mobility and service management cost for serving mobile users with diverse mobility and service characteristics. The basic idea of DMAPwSR is that each mobile node (MN) can utilize its cross-layer knowledge to choose smart router...

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...
