This document proposes a framework for mobile platforms that provides geo location and peer-to-peer communication services. It aims to develop libraries that allow developers to access location data and enable Bluetooth communication between nearby devices. The framework would include APIs for geo location, maps integration, and Bluetooth communication. It also outlines research conducted, the proposed solution, library components, and demo applications like Geoscribe and a Bluetooth chat room. The framework is intended to be portable across platforms and provide features like SOAP compliance, power management, and security customization.

1. Geo Location &
Communication
Framework for Mobile
Platform
By Benson Lim and Liu Tianwei

2. Motivations
• High growth rate of LBS on mobile phone
• Lack of simple implementation for
developer
• No easy way for communication between
neighbouring mobile devices.

3. Objectives and Goals
• To develop a library which developers can
make use of
• Geo Location and Communications
• To create applications to demostrate the
usage of our framework
• Geoscribe and bluetooth chat-room

4. Research Done
• Professional Android Application
Development by Reto Meier
• The Busy Coder’s Guide to Android
Development by Mark L. Murphy
• Sams Teach Yourself Android Application
Development in 24 Hours by Lauren
Darcey & Shane Conder
• Google Android Developers’ Forum

5. Research Done
• Broadcast-Based Peer-to-Peer
Collaborative Video Streaming among
Mobiles by Man-Fung Leung & S-H. Gary
Chan
• Bluetooth Dynamic Topology by Suresh
Srinivasan, Keyur Desai, Akash Tilak
Choudhari and Dinesh Rajan
• Always Best Connected by Eva Gustafsson
and Annika Jonsson, Ericsson Research

6. Research Done
• Practical API Design: Confessions of a Java
Framework Architect by Jaroslav Tulach

7. Solution
• Framework for
- Geo Location Services
- P2P Blue-tooth Communications

8. Solution - Con’t
• Client-based implementation
• SOAP compliance
• Power Management
• Security

10. Framework Overview

Library
Link layer

11. Applications Layer
• Mobile Games
• Chat-room
• File sharing server
• Download boaster
• GPS
• Geoscribe
• ...

12. Geo Locations Apis
• get location()
• locationToMap()
• findNearby()
• showAppUser()
• getApproxLocation()

13. Geo Location Services
• Get location
• Get misc readings, eg altitude, speed etc
• Notify users when readings changed
• To get locations of friends, with integration
from other components
• Map integrations

14. Geo Location Services
• Map Integration
• Path Calculation

15. P2P
Communication
• Seamless Connections to a bluetooth
piconet/scatter net
• Allow sending of data to one/many node of
the scatter net.
• Allow usage of resources of all node in the
ad-hoc network.

16. P2P
Communication
C
A

17. Communication Apis
• Initialize()
• routeTrace()
• getConnectedNodes()
• createNetwork
• joinNetwork

18. Libraries
• Math Library
- Range Calculations, Shortest path, etc
• Map Library
- Creating overlays, etc

19. Libraries
• GUI Library
- Create Views, modify Views, etc
• Communications Library
- sendBtye(), setSendHandler(), isSending(), recvBtye(), etc
- Encryption

20. Link Layer
• To link with platform Apis
• Allow for cross platform
implementation(portability)

21. SOAP compliance
• Simple Object Access Protocol
• Between client and server
• Standardize way of communication
• Easy integration/propagation of library

22. Power Management
• Provide developers with various modes of
operations
• High Accuracy Mode
• Power Saving Mode
• All-Rounded Mode
• User customizable Mode
• Do testing and provide developers with
statistics

23. Security
• Allow developers to customize security
settings
• Default: plug-and-play
• Application specific
• User specific

24. Geoscribe Demo
• Code Snippet

25. To be done
• Fully develop the libraries
• To design and implement the algorithm
which the bluetooth communication will
make use of
• Complete the Geoscribe and bluetooth
chat-room application

26. Timeline & Conclusion
• Before start of Semester 2
• Devise the communication algorithm
• Complete the blue-tooth chatroom
• Begin real world testing on geo
location framework, power
management

27. Timeline & Conclusion
• Semester 2 recess week
• fully develop the libraries
• complete the Geoscribe application
• Before CA4
• Done real world testing
• Push out framework and application as
an open source project
