Pointer forwarding MIPv6 mobility management

Abstract

Widespread use of the Internet at an explosive pace and progress in the operation and deployment of networks have increased the number of people whose lives are tightly involved with this global medium. In wide area deployment, heavy signaling traffic and the handoff latencies due to mobile IP registration could be high if the distance between the visited network and the home network of a Mobile Node is large. Also, base stations with small cells yield frequent handoffs, and requiring a registration with a distant Home Agent and Corresponding Nodes for each such local handoff increases overheads and further aggravates packet loss. This paper, proposes an approach to allowing Mobile Nodes to use a cascaded tunneling scheme in a mobile IP network, called Pointer Forwarding MIPv6 Mobility Management (PFMIPv6) strategy. This approach reduces the cost of updating distant Home Agent and Corresponding Nodes, which greatly reduces the number of signaling messages in the network Furthermore, the Tunneling Chain of a Mobile Node is determined dynamically with no need for preliminary definitions of static anchors or regions. The results of this work demonstrate that the new strategy yields lower average costs than the MIFv6 method, when MNs move fast, but packets are rarely received.
