ABSTRACT

This research work details the development of navigation system with the map of the University of uyo (Town and Annex campuses) on java – enabled phone. This map was created with are view GIS. Research of previous work in the fired preceded the development of a new approach that does not require GPS or full internet connectivity. Dijiktra routing algorithm is used to calculate the optimal path from user position to destination. The system is verified suitable in guiding the user from any location to the desired destination within the campuses.

                            GENERAL INTRODUCTION

1.0 INTRODUCTION:

This phone mobile – navigation system of the Uyo City Polytechnic is designed to be a powerful tool in decision-making with regards to travelling or navigating the university especially by the first timer. That is because as the power of phones (PDAs) and other wireless device grows humans problem are gradually solved with ease today, it is easy to locate one’s position with a cellular phones. Wireless spatial data service is becoming one of the fastest growing areas in information technology.

    Again the Uyo City Polytechnic is fast becoming a center of attraction for visitor due to the rapid infrastructural development and high standard of education in the institution. As a private Polytechnic  of Uyo established in capital city of the highest oil producing state. The Uyo City Polytechnic ring bell in the ear of the people within and outside the state.  These visitors who come into the institution need clear direction to their destinations. They need to know the geographic parameter of their destination in relation to their current position

  Without this guide people can get confused on finding their way within the school or stopover at every point to ask passerby of the next turn to take of course, this can expose visitors to wrong hands possibly waste one’s time on the way.

This research work then seeks to combat these problems by providing a lasting and user –friendly map of the polytechnic on the mobile phone. It is important to note that two kinds of land-base navigation system exist on one board and off –board system. On-board systems are independent systematic with a large memory and processing  capacity which enable them to store both address of the database and maps and to performed route calculation. They are typical embedded system in cars bought as stand-alone produce dedicated cars navigation.

The other approach is off-board navigation which is mobile solution usually implemented on mobile phone and PDAs. The idea is to use the built-in graphs and sound, support of these device to present the navigation .Therefore, for the purpose of this research work, a phones-based mobile navigation system is designed and analyzed using java and XML technologies format and applying in java program and interface with a search module to select the current location and destination will be developed, which will use java code, and XML parser to act on XML and result display using java graphical procedure,

 1.1 STATEMENT OF THE PROBLEM

1)   Visitor often get confused in the school campus trying to locate their destination  

2)   New  student in school campus often miss lecture because they were not able to locate the hall  which the lecture is hailed

3)   Tourist is not always free in their movement and in school

4)   Inability of people to know the geo-parameter of their destinations when the need they always lead  them to wrong hand

5)   Waste of people times

1.2    AIMS/OBJECTIVES OF THE STUDY

        The specific objectives of the system with include the following

1.   To  allow the user select their current location and destination on the mobile phone

2.   To guide the user  along some path to the intending destination

3.   To give a graphical representation (map) of the distances between the current location and the destination point

4.   To create a user-friendly interface for the navigation system 

1.3   SCOPE AND LIMITATION OF THE STUDY

Despite the enormous   benefits of using handled devices their short-comings are striking which include restricted memory, less computational power, less speed and instability .this actually affects the size of the database and large completion not too good with this kinds of devices. Following these limitation, not all the buildings in the campus were considered for this design but the major sport were covered                     

1.4 HOW TO SOLVE THE PROBLEM /SIGNIFICANCE

      The problem will be solved by integrating the two technologies (java and XML) on a mobile phone which will result on the high performing navigation speed, with enticing interface in comparison with c conventional system, and when the application is installed in the mobile phone it will interact with the positional information receiver available in the mobile phone to collect positional information system (GPS) mobile tower.

GPS is satellite-based navigation system, utilizing a constellation of at last 24 medium earth orbit satellite that can transmit précis microwave signals the system enable the GPS receiver to determine its own location ,speed and direction with and  external positional information receiver with the application establish a wireless connection using Bluetooth communication protocol or wire connection using serial protocol or will take advantage of the cellular phone network to deliver real time information such as current position and location of the user will b connected directly to the network server whenever a user  request for a map  information

therefore in solving the problem the system will allow a user to select current location and destination guide a user along some paths to then contenting destination and give graphical representation (map) of the distance between the current location and the destination point, depending on user query and final output is shown to the user on the user information which will displayed on the mobile phone                           1.5HOW THESTAKEHOLDERS WILL BENEFITS FROME THE PROJECT

a)   Phone-based mobile navigation will make sure that a tourist is very free in school and in their movement. Because many people visit university uyo on daily basis either for academic conference, business, seminars, cooperate meeting tour excursion, picnic religious convention and the list of endless. These people would want to have a “feel of school campus’’ and get to interesting block within the campus on their own, but don’t usually find it easy doing so expect by a close human direction.

b)   It will be very helpful to new student on school because most of the student often miss lecture’s because they were unable to locate or identify the hall which the lecture is hail. This project will help in solving this problem by providing a lasting and user friendly map of university on a mobile phone for a new student.

c)   visitor often stop over at every point to ask passerby of the next turn to take their destination ,which can expose them to wrong hand and possibly waste their time .therefore the project will help in solving this of people (visitor) getting confused within the school

1.6 WHAT IS WIRELESS SPATIAL DATA SERVICE

Oxford advance learners dictionary (new 8th edition) defined the following word defined the following words below as

WIRELESS:  it a system of sending and receiving am signals without using wire e.g.  A radio

SPATIAL: relating to a space and a position, size, space etc of thing in it or the ability to judge the position and size of   object

SERVICES: a service is a system that provides something that the public needs, organized by the government or a private company

        in  computer science ,wireless, spatial data  service defined as application programming interface (API) provides  a  representational state transfer (REST) interface that can geo code , store and query spatial data .this  simple REST interface accomplishes task by setting  parameter in a uniform resource allocation ( URL) and then submitting  the URL as an HTP request. The HTTP responses return the result of the request

A phone based mobile navigation system is discussed as an application when installed in the mobile phone enable the used of mobile phone as a navigation system. The application can adjust to various feature of the mobile phone and utilize phone memory or external memory to store the navigation information and mps.

      The mobile with the application installed inside can obtain positional containing signals transmitted both from global positioning system (GPS) satellite as well as the mobile tower.

The application use positional information to obtain navigational information. The positional and navigational information are précised by the application to obtain location mobile phone display on screen to interact with the user and display the location information.

1.7 DEFINTION OF TRILATERATION:

       Global positioning system (GPS) navigator use the mathematical technique of trilateration to determines user position, speed and elevation. GPS navigator contents receive and analyze radio signals from GPS  satellite calculating precise distance  range to each satellite being tracked .data from a single satellite  narrow a position down to a large area of the earth ‘s  surface . Adding from a second satellite narrow position down to a region where two spheres overlap, adding data from a third satellite provide relatively accurate position  data from a further satellite e(or more enhance precisions and  also ability to determine accurate elevation or altitude (in case e of aircraft )GPS receivers routinely track 4 to 7 or more satellite simultaneously . if a GPS navigator is receiving insufficient  satellite data (not able  to track  enough satellite ) it will notify the user rather than providing incorrect position information.
