Project Goal

• Create a Location Aware Instant Messaging
  Application
• Implement a program which has a special behavior
  depending on user location

4
System Overview

• The System will be implemented as Client Server
  design.
• Client- Instant messaging application running on
  mobile device.
• Server- A Centralized Server will collect
  location data from the client, and connect users
  through chat groups for instant messaging. The
  Server will operate on a Windows platform.

Program Flow

• Client
• The client collects signal strength (RSSI, which
  can be used to determine location)
• The client sends RSSI data to the server via RTC
  API (over SIP protocol).
• The client sends and receives instant messaging
  messages from the server via RTC API (over SIP
  protocol).

7
Program Flow contd

• Server
• The Server Receives RSSI Data from the client via
  JAIN SIP Stack (over SIP protocol)
• The Server uses the RSSI data to calculate the
  clients location using Location Calculation and
  Distance Calculation plug-ins.
• The Server stores data about users location
  through time in the SQL database using SQL
  controller

8
Program Flow Contd

• The Server holds data about user messaging groups
• The Server sends and receives messaging data from
  the client using JAIN SIP Stack (over SIP
  protocol)
