1. Introduction

Living in the modern information technology era, we rely on a vast number of information sources.

Starting from old age newspapers to the Internet, information is presented in different ways depending on their

characteristics. Newspapers are up to date only to the extent of the date and time it was print. But the modern

sources such as internet communication have real time updating content which can be updated whenever

necessary. The internet is a global information source, this means that the internet can be accesses from almost

any location where the connectivity to the WWW exists and it contains information about and from all over the

world. So that when we query for information the results of the query contains a large set of information. This

information may or may not be relevant to the information that we actually want, but with the advance

technology, search engine providers use different ways to provide the users with the best matching set of

information to the query.

1.1 Problem specification

The existing sources are lacking the ability to provide us with accurate, up to date localized

information. This means the users who query for information are provided with a load of un-related information.

This is the problem that will be address mainly by the LIBS system framework. LIBS will present a framework

for obtaining and providing Localized Information to users. Querying information from the internet search

engines is a very common activity we do daily when searching for information. The most common experience is

to use keywords to Google information from the web. Google search engine is one of the robust search engines

that exist. It identifies your locality in parallel to the query and uses the locality information to optimize the

found information set and make it more suitable for what we query. Simply it guesses out your personal

preference and tries to match its respond to suite your needs. This process is known as localizing.

Another major approach for localized information is in use by mobile operators worldwide. This is

commonly known as Cell Broadcasting. Mobile phones are serviced by nearby service towers which belong to

the service provider and these towers are capable of servicing only up to few kilometres of range only.

Therefore many towers are staged in a small area or city. This formation has provided the facility to select a set

of towers and broadcast a message to a selected set of towers so that only the mobile phones in that selected

range will receive the message. This system is used for traffic information broadcasting as well as news and

emergency situation broadcasting. The recent Tsunami Warning System which was implemented after the

disaster was equipped with this cell broadcasting technology so that the people near the coastal area can be

warned as soon as an Tsunami threat is sensed. People who have access to the mobile network through their

phone will receive localized information from the nearby service tower. So the user gets only what he needs in

that specific geographical area but not all the unnecessary information.

After analysing the existing systems many of its limitations were identified. LIBS was designed to

address most of the limitations of the existing systems. Most of the existing systems lacked the interactivity

between users and the services while some of the systems were limited only to text based information services.

And any of the existing systems did not have a localization range less than 3 kilometres. Goggles search engine

facility was localized only up to the level of a country. This was ideal only for the people who queried


7/33



information related to country specific information. But this was not the scenario in most of the Google search

users.

1.2 Solution outline

After analysing and identifying the limitations of existing approaches and, LIBS Localized

information browsing system was designed to address these issues and to take the localization to greater level so

that the users are actually experiencing the information in their proximity. This means users can actually reach

into the details acquired from the system. The locality of LIBS is defined by the range of operating distance of

Bluetooth wireless technology, which ranges from 10- 100 meters in radius. The system mainly consists of a

java based mobile application which is installed on a Bluetooth enabled mobile phone, which communicates

with a nearby Bluetooth access point to request for services. These access points are the next major component

in the LIBS framework. Access points acts as service providers and there can be many access points linked

together and managed by one Access Point Manger. Access Point Manager is the other component in the

framework which connects the access points and connects them to a centralized database.

1.3 Key Benefits

LIBS framework is a low cost and high efficient solution for localize information which can be used by

the majority of users. Other than the mentioned advantages it has more security due to the enclosed nature and

less ex posure to the other networks. LIBS also inherit the security features that exist with the Bluetooth

communications. A successful implementation and continuation of this framework is expected to introduce new

behavioural changes in the society for information browsing.

2. Literature Review

Special Terminology Used in Literature Survey

Following is a list of commonly used terms and the definition of it related to this document.1. Localized Information - Information related to a particular place or area.2. Bluetooth a short range wireless technology for connecting different devices such as computers and

mobile phones

3. Accessibility Services services that help people with physically disabilities.4. Proximity nearby, in the range of vicinity.

Living in the modern society, we all heavily rely on different kinds of information. Information such as local

weather reports, News, Internet, Email, online directory services etc. Out of this information, localized

information has a greater value because users feel that the information is customized to them. Localized

information is a category of information where the information is filtered, formatted and presented according to

the location where the user is accessing the information. Information services such as Google, Yahoo search

engines already provide localized information by providing language localized and position localized

information to the users.

2.1 Existing approaches for localized information:

2.1.1 GSM Cell Broadcasting

Cell Broadcast is designed for simultaneous delivery of messages to multiple users in a

specified area. Whereas the Short Message Service - Point to Point (SMS-PP) is a one-to-one and one-to-a-few service, Cell Broadcast is a one-to-many geographically focused messaging service. Some

mobile operators use Cell Broadcast for communicating the area code of the antenna cell to the mobile

user (via channel 050), for nationwide or citywide alerting, weather reports, mass messaging, location

based news, etc. Not all operators have the Cell Broadcast messaging function activated in their

network yet, and many handsets do not have the capability to support cell broadcast.

2.1.2 Google Corporation

Global information services companies such as Google Inc have understood the value of providing localized

information and have implemented different solutions.

y Automatic redirection to country home page in Google Search (www.google.lk)y Display advertisements relevant to Sri Lanka. y Translate foreign language pages to local languages.

Localized language, maps, search, businesses, Adwords, Adsense

y Google has taken initiative to provide localized information country wise in most of their products andservices but it does not provide locality beyond the Country level.

y Google does not provide a way of interacting with the information. We can only view the information.2.1.3 Mobile Access by Axis Communications

A Bluetooth Access point hardware device providing network services over Bluetooth.

2.2 Problems of Existing Approaches

y Locality is not accurate to more than few kilometersy No Interaction with information. Only broadcast/receive is possibley High cost of implementation (high cost, special equipment)y High cost of usage (mobile carrier and data transfer charges)y No advance information exchange mechanism.y Not widely adopted by users

2.3 How LIBS addresses the problem in existing approaches.LIBS introduce a framework which can be applied in many industries and organizations.

LIBS is an Interactive Information service including news,games,entertainment.

LIBS is a very low cost solution in implementation and usage.

LIBS inherits security features built in Bluetooth such as encryption, hidden mode communication and key

sharing

Localization of information is from a range of approximately 10 100 meters, which is very much localized

than other existing services.

LIBS use Bluetooth wireless technology.

3. Research Problem

The main research component is based on how technology can be used to bridge the gap between

localized information and people. When it comes to information we are looking at an infinite set of

information, therefore, for the research to be feasible we have selected four subject areas to focus and to

identify how technology can be used to bridge the gap between the selected subject areas.

3.1 Common Research topic

How technology can be used to bridge the gap between localized information and people

3.2.1 Research on how Localized Information can be used in Educational

Services related industries and services

Education is an essential service considering any part of the world. The main reason for all of the

advancements in technology is due to the basic education gained throughout life, enriched with past education

and experience. Even though Education is considered a global service the methods, modes and content of

education vary from place to place. A child living in China will be learning in the Chinese language while a

child living in Sri Lanka is learning the same content in Sinhalese. This simple e xample significantly identifies

the importance of Localized Information.

The ability to access to new and updated information is very essential in his or her education process.

This is why the information should be localized to suite specific needs and areas of study. One of the approaches

by a leading organization, Google is the scholar searching facility which provides research papers and

documents related to a specific subject area. But it is still localized only up to the country level.

A high level of localization in information should be achieved in educational services to avoid the

problems such as:

y Occurrence of un-related information in educational informationy Occurrence of out dated information of subject matter.y Long time taken to process and understand information hard to learn and concentratey Information not satisfying personal preferences such as language, age, gender etc

The LIBS framework applied to the educational services is targeting towards overcoming the problems

mentioned above and helping the process of learning. There are three modes of formal learning.

y Visual: learning based on observation and seeing what is being learned.y Auditory: learning based on listening to instructions/information.y Kinesthetic: learning based on hands-on work and engaging in activities.

LIBS framework in implementation related to my research area is expected to fully covers the Visual and

Auditory learning modes and well as the kinesthetic mode partially

Following are few applications of localized information of LIBS application.

y Sharing of Localized Educational materials to a mobile device straight from the lecture hally

Interactive Educational Quizzes using the mobile phone to improve knowledgey Interactive learning activities using the mobile phoney Question rising to lecturer through the system.y Polls and Answers related to subject matter thorugh the system.y MCQ or text based exams through the system.y Provide information or notices to students through the system.

4. Objectives

4.1 Common Objectives

The overall objective of the project is to develop a,

1) Framework for 2) browsing Localized Information that is 3) low in resource usage and 4) widely used

an applied.

The overall objective is explained in more detail in the following section which also covers the projects sub

objectives such as security and interactivity of the system.

1) The Framework

LIBS introduce a set of components and processes which can be implemented using different

technologies for Localized Information Browsing. The project concludes by implementing the

introduced framework using a set of selected technologies to show its applicability.

2) Localized Information Browsing

Localized information refers to Information concentrating or related to a particular place or

area. Therefore the locality of the proposed system is expected to be around 10-100 meters.

3) Low Resources usage

The system is expected to be widely used and adopted by many industries, so the design will

be done to low the cost of implementation and operation. The basic cost of implementation

will only be the cost of a standard personal computer with a Bluetooth dongle only.

4) Wide usage and Application

This Localized Information Browsing System is very important for someone who may not

have full use of their legs or arms, many disabled, injured, or elderly individuals who are

unable to do works by them self.They can receive data across their mobile phones.

Security

The Bluetooth Access Point provides a flexible foundation for access control, security and

other management and administration functions for data.

Interactive System

Receive all updated information very Robust and very soon in attractive way which also help

to disabled people.

5.1.1 LIBS System Framework

5.1.1.1 Framework Components

The LIBS framework consists of three major components interacting

1. Mobile Communicating Devices (MCD)2. Service Access Points (SAP)3. Access Point Manager with Database connectivity


16/33



5.1.1.2 Component interaction of framework

The mobile communication device will search and connect to the nearby service access point to re quest for

services and interact with it. Then the service point will communicate with the centralized access point manager

where further database communication or authorization is needed; else the access point will provide full serviceto the connected mobile communicating device. The services can range from simple broadcasting of text

information to complex games, multimedia and interactive information.

Mobile Communication Devices should communicate with the service access point through a wireless

communication technology. The main reason to define a wireless communication between these two

components is that they are mobile devices which are on the move at most times. Other than that wireless

communication methods are efficient and hassle free communication methods which have been in use. Wi-Fi,

Bluetooth, ZigBee, IR are some of the commonly used wireless communication methods that can be used in

LIBs framework. Communication Protocols between MCD and SAP could be any state-full communication

protocol.

The Service Access Points communication with the Access point managers should be implemented with any

standard communication method. Preferably with TCP/IP protocol support. The Access point manager should be

able to manage the state of its connected Access Points.

The Access point manager should be implemented with the singleton approach so that many Access Points can

communicate with one access point Manager and get its advance services while the manager can manage several

Access Points at once.

The Database should be any standard relational database which is only connected to the Access point Manager.

The database can be implemented using additional features such as replication and firewall support as necessary.

Bluetooth is an open standard specification for a radio frequency (RT )-based, short-range connectivity

technology that promises to change the face of computing and wireless communication and that provides the

network infrastructure to enable short range wireless communication of data and voice. It comprises of a

hardware component and a software component. The specification also describes usage models and user profiles

for these models. It is designed to be an inexpensive, wireless networking system for all classes of portable

devices, such as laptops, PDAs (personal digital assistants), and mobile phones. It also will enable wireless

connections for desktop computers, making connections between monitors, printers and keyboards.

The Bluetooth specification aims to allow Bluetooth devices from different manufactures to work with each

other, so itis not sufficientto specifyjust a radio system. Because ofthis, the Bluetooth specification does not

only outline a radio system but a complete protocol stackto ensure thatBluetooth devices can discover, explore

and use these services with each other.

Bluetooth is a standard wire-replacement communications protocol primarily designed for low power

consumption, with a short range (power-class-dependent: 100 m, 10 m and 1 m, but ranges vary in practice; see

table below) based on low-cost transceiver microchips in each device. Because the devices use a radio

(broadcast) communications system, they do not have to be in line of sight of each other.

In most cases the effective range of class 2 devices is extended if they connect to a class 1 transceiver, compared

to a pure class 2 network. This is accomplished by the higher sensitivity and transmission power of Class 1

devices.

Version 1.2 1 M bit/s 0.7Mbit/s

Version 2.0 + EDR 3 M bit/s 1.4Mbit/s

Version 3.0 + HS 24 Mbit/s

While the Bluetooth Core Specification does mandate minimums for range, the range of the technology is

application specific and is not limited. Manufacturers may tune their implementations to the range needed to

support individual use cases.

5.2.1.3 Bluetoote

profiles

To use Bluetooth wireless technology, a device must be able to interpret certain Bluetooth profiles, which are

definitions of possible applications and specify general behaviours that Bluetooth enabled devices use to

communicate with other Bluetooth devices. There are a wide range of Bluetooth profiles that describe many

different types of applications or use cases for devices.

5.2.1.4 Bluetootf

Specification

Bluetooth Specification defines the requirements ensuring interoperable operation between Bluetoothtransceiver from different manufacturers. There are two major areas in Bluetooth specifications: the radio and

protocol definitions (protocol stack), and the compliance requirements.

Each channel is divided into time slots 625 microseconds long. Packets can be up to five time slots wide. In this technique, a device will use 79 individual, randomly chosen frequencies within a designated

range.

Data in a packet can be up to 2,745 bits in length. Has been set aside by the ISM for exclusive use of Bluetooth wireless products. Communicates on the 2.45 GHz frequency Bluetooth uses a technique called spread-spectrum frequency hopping. Transmitters change frequency 1600 times a second. Three areas - Data and Voice access points, Cable replacement, and Ad hoc networking. Supports point - to - point as well as multi-point. Low power.

6.2 Special Equipment Requirements

Bluetooth ongle.

In order to build Bluetooth access point we may need Bluetooth dongle. Via this access point client can access

to information which we are sharing. Therefore to provide fast and reliable services, we need 2.0 or higher

version of dongle with 3Mbit/s data rate and 1.4 Mbit/s maximum application throughputs. Also that dongle

must be class 1 or 2 (Range approximately 10 to 100 meters) and must compatible with Windows operating

systems. Also the cost for a single device is low. [4]

JAVA and Bluetooth Enabled Cellular Phone.

Client use cellular phone connects to our system. That cellular phone must be a JAVA enabled one. Because

before connect to our system client want to install our client application to that phone. Also to connect our

Bluetooth access point phone must be a Bluetooth enabled one. When we develop our system we hope to use

JAVA and Bluetooth enabled cellular phone to test client application.

Other resources such as Desktop or Laptop computers are not considered as special requirements.


30/33



7. Budget with Budget Justification

The proposed solution has a low budget due the re use of available resources and hence can be considered very

practical and implementable even in developing countries such as Sri Lanka.

Mobile A pplication - No Cost Bluetooth dongle - 400 LKR Centralised Server - 40,000 LKR PC - 15,000 LKR Software's - 10,000 LKR

Initial testing cost is not calculated due to the reason that our group members are equipped with the devices

needed for full implementation and testing.

In planning the budget we are excluding the costs for cellular phone. Because all of our project members already

have JAVA and Bluetooth enabled cellular phones.

The actual users phone cost is excluded from the implementation cost.

The Marketing Value of the system is of a considerably high value and these monitory incomes can be used for

further development and research in return.
