Abstract
Proxy Mobile IPv6 (PMIPv6) is a network-based localized mobility support in IP network. The main advantage of using PMIPv6 is the freeing up of the mobile host in doing any mobility related activities and thereby saving its resources. However, the Mobile Access Gateway (MAG) incurs a high signaling cost to update the location of a mobile node to the remote Local Mobility Anchor (LMA) if it moves frequently. It may cause excessive signaling traffic and increase a high traffic load on LMA. Therefore, we propose an adpative mobility management scheme in PMIPv6 networks with IP paging support. To minimize signaling overhead, in our proposed scheme, an idle mobile node does not register when moving within a paging area. Moreover, we will employ the anchor-subnet concept and techniques to reduce signaling costs for paging and delay. The cost analysis using Stop-or-Move Mobility (SMM) model presented in this paper shows that our proposed scheme can achieve performance superior that of the PMIPv6 scheme.
