1 Investigation into developing stand-alone Location Based services (LBS) Nkululeko Gojela Supervisor: Dr Hannah Thinyane

2 Background “…services that integrate a mobile devices location or position with other information so as to provide added value to the user” Schiller and Viosard

3 Background Types of Location Based Services Type 1 – Those that are dependent on an aggregation infrastructure (Central server with application logic) Type 2 – Those that are independent of an aggregation infrastructure (Standalone) Getting location information: 1.GPS based 2.Network Based (Cell operator) 3.Hybrid (Combination of 1 & 2)

4 Purpose of Project To investigate the development of LBS: – Do not requirement aggregation infrastructure. – Possible methods for developing the services – Which method offers: Maximum portability With maximum location accuracy – How does the portability and location information accuracy divide the types of LBS that can be developed.

5 Development Approach Two approaches: 1.J2ME : Applications on installed on device. – Why? Java is designed for platform independence J2ME Location API - gives applications the opportunity to use a device's location capabilities In Location API the Location Provider supplies information about the location of the devices based on criteria given. Criteria include – accuracy, response time.

6 Development Approach 2.Java Card Techonology : Applications running on smart cards. – Why? Java is designed for platform independence Allows for applets written in Java to be execute on smart cards. Offers portability because the applets are not/less dependent on device platform. But memory restrictions affect what you can or cannot do on the card. Also enable acquiring of location information from sim/smart card applet level. Provide JCVM, RE and Java Card API for developing Card applets.

7 InvestigationApproach Investigation Approach – Investigation approach is to develop LBS using both methods. LBS will allow use to view location information Set landmark on the application Events triggered whenever currently location information matches the landmarks. – Evaluate the outcomes of the How does location information affect the type of service (accuracy)

8 Progress – Understanding the development environments J2ME + Support for LBS Java Card Technology and Gemalto Developer Suite. – Examining the technologies support for LBS

9 Tools J2ME Platform SDK Gemalto Developer Suite and Simulator Mutiple mobile device platforms – Symbian OS, Andriod, iPhone OS, possibly Windows Mobile

10 Mobile Platforms
