Economically Viable Support for Internet Mobility

The support for mobility is a major requirement for the future Internet. Although several mobility solutions have been proposed, none of them has been largely deployed, mostly because they are not economically viable. We propose a business oriented mobility framework - Mobility Support Service (MSS) to be offered as a value-added service to paying mobile customers. MSS uses Identifiers (IDs) to locate the nodes and network addresses as points of attachment for the nodes. MSS is a scalable distributed service. MSS does not require changes in existing network architecture nor services. We present two MSS distributing algorithms that enable tradeoffs among costs and QoS. We show by simulations the advantages of MSS compared to existing mobility solutions, especially regarding scalability and service delay. However the main advantage of MSS is that it can be realistically offered, because it is economically viable.
