  1. e-Gossip: Location Based Service via Electronic Gossip Presented by RizwanaRizia

  2. Outline • Basic Idea of LBS • Systems in Literature • Our Proposed Model • Motivation • Comparison • System Components • References

  3. Basic Idea of LBS • Smart phones can detect geographical locations • Location based services are becoming more and more popular. • Location based services detect user location and provide location specific information.

  4. Basic Idea of LBS (contd…) • Important capabilities of location based services from user point of view • High Performance • Scalable Architecture • Reliable • Current • Mobility

  5. Systems in Literature Figure 1: Generalized Picture of Traditional LBSs

  6. Our Proposed Model Figure 2: Proposed Model

  7. Motivation • People want to share knowledge • Sharing of knowledge can be useful • We are not always aware of everything around us

  8. Comparison

  9. System Components • Generate the database on smart phones • Search Information

  10. System Components (contd…) Algorithm to generate ‘Location Database’: Step 1: Smart phone monitors user location continuously Step 2: Detect new location not in database Step 3: Considers for notifying user if the user stays in that location above a threshold interval, e. g. 10 mins Step 4: Notifies user and asks to provide keywords, comments, rating. Step 5: Takes user permission to publish the location.

  11. System Components (contd…) Prototype Location Update:

  12. System Components (contd…) Algorithm Search: Step 1: User types keyword in the interface Step 2: The Application gets a list of available E-Gossip Devices around via Bluetooth. Step 3: The application connects to each device and search into their database with the keyword. Step 4: The application provides a list of available locations.

  13. System Components (contd…) Prototype search:

  14. System Components (contd…) Search using bloom filter: Probability of false positive: where m = size bit array, n = number of elements

  15. System Components (contd…) Search using bloom filter (Contd…)

  16. Conclusion • Information may not be available via e-Gossip • Uncommon address and context based information is specialty of e-Gossip
