Design and Implementation of Mobile Handoff Scheme Based on Identifiers Separating and Mapping
Traditional Internet is originally designed for fixed terminals and cannot provide proper support for mobility. The Universal Network: introduces Access Identifier, Switch Route Identifier, and the separating and mapping scheme of Access Identifier and Switch Route Identifier, which can well support mobility. We design a novel network-based handoff scheme in the Universal Network. The entire handoff mechanism comprises of three processes: mobility detection, authentication and authorization, and location update. We implement the handoff scheme in Linux platform. The experimental results show that handoff delay between 23.5ms and 35ms, which indicate that it can satisfy the needs of the Universal Network's mobile handoff.
