The document proposes a scalable and efficient location database architecture for future mobile networks based on location-independent personal telecommunication numbers (PTNs). The proposed multi-tree database architecture consists of multiple database subsystems, each with a three-level tree structure connected only through the root. This architecture reduces database loads and signaling traffic by exploiting localized calling and mobility patterns. Two memory-resident indices are also proposed to further improve throughput. Analysis shows the architecture can effectively support high user densities in future mobile networks.

ABSTRACT
The next-generation mobile network will support terminal mobility, personal mobility, and
service provider portability, making global roaming seamless. A location-independent personal
telecommunication number (PTN) scheme is conducive to implementing such a global mobile system.
However, the nongeographic PTNs coupled with the anticipated large number of mobile users in future
mobile networks may introduce very large centralized databases. This necessitates research into the
design and performance of high-throughput database technologies used in mobile systems to ensure
that future systems will be able to carry efficiently the anticipated loads. This project proposes a
scalable, robust, efficient location database architecture based on the location-
independent PTNs.
The proposed multitree database architecture consists of a number of database subsystems,
each of which is a three-level tree structure and is connected to the others only through its root. By
exploiting the localized nature of calling and mobility patterns, the proposed architecture effectively
reduces the database loads as well as the signaling traffic incurred by the location registration and call
delivery procedures. In addition, two memory-resident database indices, memory-resident direct file
and
T-tree, are proposed for the location databases to further improve their throughput. Analysis
model and numerical results are presented to evaluate the efficiency of the proposed database
architecture. Results have revealed that the proposed database architecture for location management
can effectively support the anticipated
high user density in the future mobile networks.

In existing system different databases are used for each and every node. Here a node contains only their
own data and doesn’t search data of another nodes .Here the node can use their own data from a
particular database.

MODULES:
1. Network: Here we are using centralized database for constructing network. In this
Module we are using 3 different nodes for constructing network. After login each and
every node can use the data from the centralized database.
2. Search: Here 3 different nodes can search the data from centralized database. A node can
search the data from its own space if the file is not available it can also search others
nodes space.
