ABSTRACTy The next-generation mobile network will support terminal mobility,
personal mobility, and service provider portability, making Location
Tracking seamless.
y A location-independent personal telecommunication number (PTN) scheme
is conducive to implementing such a global mobile system.
y In this paper, I propose multi tree database architecture consists of a number
of database subsystems, each of which is a three-level.
y It also proposes indexing schemes for each type of location databases and
analyzes their efficiency and cost in terms of database access time andstorage requirement.
y Results have revealed that the proposed database architecture for location
management can effectively support the anticipated high user density in the
future mobile networks.

INTRODUCTIONy THE next-generation mobile network will be an integrated global system
that provides heterogeneous services across network providers, network
backbones, and geographical regions.
y Location Tracking is a basic service of the future mobile networks, where
terminal mobility, personal mobility, and service provider portability must
be supported.
y In a wireless network, a node (mobile-phone) will be present in a region and
each region will have a MSS.
y
Mss is mobile-switching-station or tower. Each mss will have up to dateinformation of all the nodes under its control. Nodes will be continuously
roaming i.e. it will change its location randomly.
y When ever a node leaves a region and enters another region, two region's
mss will be updated. Each mss contains two databases namely HLR and
VLR.

CONT..y The next-generation mobile network will support terminal mobility,
personal mobility, and service provider portability, making global roamingseamless.
y A location-independent personal telecommunication number (PTN) scheme
is conducive to implementing such a global mobile system.
y However, the nongeographic PTNs coupled with the anticipated large
number of mobile users in future mobile networks may introduce very large
centralized databases.
y 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.
y This paper proposes a scalable, robust, efficient location database
architecture based on the location- independent PTNs.

y 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.
y 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.
y 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.
y Analysis model and numerical results are presented to evaluate the
efficiency of the proposed database architecture.
y Results have revealed that the proposed database architecture for location
management can effectively support the anticipated high user density in the
future mobile networks.

CONT..y Mobility management is a major challenge in mobile ad hoc networks
(MANETs) due in part to the dynamically changing network topologies.
y For mobile sensor networks that are deployed for surveillance applications,
it is important to use a mobility management scheme that can empower
nodes to make better decisions regarding their positions such that strategic
tasks such as target tracking can benefit from node movement.
y In this paper, I describe a distributed mobility management scheme for
mobile sensor networks.
yThe proposed scheme considers node movement decisions as part of adistributed optimization problem which integrates mobility-enhanced
improvement in the quality of target tracking data with the associated
negative consequences of increased energy consumption due to locomotion,
potential loss of network connectivity, and loss of sensing coverage.

CHARACTERISTICS
y MANET generally has the following characteristics:
y New members can join and leave the network any time.
y No base station is available to provide connectivity to backbone
hosts or to other mobile hosts.
y It is difficult to implement this scheme for handover and
location management.
y Each node acts as a router, forwarding packets from others
nodes.
y Communication connectivity is usually weak in the sense that
it is easily broken due to node movement.

y The previous mobile network was use different server and
each has decentralized databases.
y A local server is stored only its area users information, but
not stored the other area users information.
y For example Chennai mobile user call to the Srilanka user
means, First it search in the local mobile user and after
finished search in India and then find it in the Srilanka
server.
y It takes more time to find the user location because ofdecentralized databases.
y The communication traffic also occur when search client
side.

LIMITATION OF EXISTING SYSTEM
y Its based on location dependent PTN.
y Does not have a mobile freedom for global wise.
y Database will vary for each and every country and will not access by other
country.
y We cant able to get the clear database details of other country.
y The PTN will not able to access from one country to other country.
y PTN will vary from country to country.

PROPOSED SYSTEM
y In proposed system, the mobile network search only in server but not inclient mobile. Because all users information maintained in centralized
database server.
y The proposed multi tree database architecture consists of a number of
database subsystems, each of which is a three-level tree structure and isconnected to the others only through its root.
y 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 deliveryprocedures.
y In addition, two memory-resident database indices, memory-residentdirect file and T-tree are proposed for the location databases to further
improve their throughput
