Introduction

• Bluetooth Technology
• Is a wireless networking technology that provides
  a way to connect and exchange information between
  devices
• These devices could be
• mobile phones
• Laptops
• PCs
• Printers
• digital cameras
• And others
• Connection is over a secure short-range radio
  frequency.
• The connection range is only a few meters
• Class1 100 meters
• Class2 10 meters (widely used)
• Class3 1 meter

Project goals

• Based on Bluetooth technology we would like to
  create a system that is able to
• Keep track of the location of Bluetooth device
  users
• Based on the BT Access Points that identify the
  users
• Their current location
• Their path
• Send them messages

6
Project Applications

• Examples of The applications of the system
• Commercial
• Special promotions while roaming a mall
• emergency services
• Pinpointing the location of doctors in a hospital
• Locating lost children

7
Design

• The System will be implemented as a Server Client
  system
• The Client part
• The Client is a Linux workstation that is used to
  gather information from nearby BT units and sends
  them to the server (i.e. functions as a BT Access
  Point)
• Each access point will run this program
• The Server part
• Gathers all the data from the clients
• Analyzes this data and calculates their location
• The BT Units
• There is no need for any program (i.e. any BT
  device nearby is automatically connected)

8
Design (cont.)

• System process
• Client application will collect information from
  nearby BT Units and functions as BT Access point.
• It then creates a data packet containing this
  data and send it to the server
• Since the Server knows the location of each
  client so it calculates each BT users location
  according to the Clients that know him according
  to a location calculation algorithm
• Then we can make use of the data by
• Sending messages to the user
• Displaying the user as a picture on the map

What is your name
Hai is around and say Hi
Hello I am here
My Name Is Hai
Calculate location
What is your name
Hai is around and say Hi

• Study C .. 1 week
• Learn WifiWhere project code .. 3 weeks
• Site
• Few changes to the code in the server part .. 2
  weeks
• Change the way of saving and loading plans
• Change the Location plugin interface
• Add a few location plugins
• Listen to TCP Connections (instead of UDP)
• Define the incoming package format

11
Time Schedule (cont.)

• TODO
• Write a dummy client and make sure that the
  client server TCP/IP communication is working OK
  .. 2-3 weeks
• Read the Bluetooth booklet .. 1-2 weeks
• use the dummy client to write the client with
  Bluetooth communication .. 3-4 weeks
• Write a good location calculation algorithm .. 1
  week
• Celebrate D
