  1. Investigation into developing stand-alone Location Based services (LBS) NkululekoGojela 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: • GPS based • Network Based (Cell operator) • 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. DevelopmentApproach • Two approaches: • 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. DevelopmentApproach • 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 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
