Design And Implementation Of A Location Management Scheme In Universal Network

ABSTRACT: The original design of current information network is a decoupled mode that one specific network supports one major service. The Universal Network introduces AID (Access IDentifier), RID (Routing IDentifier), and the mapping scheme between the AID and RID, to support the pervasive services.This paper presents a location management scheme to manage the location information of all kinds of terminals effectively. This scheme borrows some ideas from the existing Internet and mobile networks. Under this scheme, the network is divided into several regions according to the geographical location and quantity of users. For each region, there is an identifier server (IDserver) responsible for managing the location information. The IDserver provides query service for the access routers in the same region. When a terminal moves to another region, the access routers communicate with the IDservers in different regions following the communication protocol to update the location information. This scheme borrows the concept of home region in mobile network, and defines a field called Home Region in AID to ensure that the access routers could find the location of any terminal by looking up in the IDserver at its home region. This scheme also defines a field called Type of Equipment in AID to manage the heterogeneous terminals effectively in terms of improving the efficiency of location update and querying, and reducing the burden of core network.We deploy this location management scheme on the experimental network and do some related tests on functions and performance. The results indicate that this scheme can meet the basic requirements of the communication in Universal Network, including location registration, update and query. The implementation of this scheme builds a foundation for further research on Universal Network.
