A mobility protocol framework to support multiple namespaces

Abstract

This paper presents a new mobility protocol that supports multiple namespaces on IPv6 networks. Our proposed protocol framework allows a mobile node to specify a correspondent node by a name that is defined in any namespace as a node identifier. This technique removes certain restrictions on the space of node identifiers and allows mobile nodes to communicate with each other regardless of their location. Mobile nodes negotiate a pseudo node identifier which is unique between the two nodes, with a correspondent node that is identified by the name. We make this pseudo node identifier compatible with the IPv6 address format; we can thus use existing IPv6 applications with our proposed mobility framework. This framework is based on Location Independent Network Architecture (LINA), and provides mobility support in a simple fashion and with low protocol overhead. We also demonstrate how to provide anonymity to our mobility protocol by using a dynamic pseudo node identifier.
