Project Goals

• Implement a mobile model of bluetooth units.
• Implement routing protocol(s) of BT Scatternet on
  OPNet simulator.
• Measure the BT Scatternet performance

BlueTooth Overview

• Bluetooth is the codename for a technology
  specification for small form factor, low-cost,
  low-power, short range radio links between mobile
  PCs, mobile phones and other portable devices.
• A global specification for wireless connectivity.
  Bluetooth is a cable replacement technology that
  simplifies the interaction between people as well
  as machines.

Problems Solutions

• Issues
• The bridge functionality
• How to maintain connection with more than one
  piconet.
• How frequently the bridge should switch between
  piconets.
• Bridges state when switching between piconets.
• Mobility model of bluetooth units.
• The scheduling policy inside the piconet
• Round Robin policy
• Fixed/Adjusted Priority to bridge within the
  piconet

• Our decisions
• The bridge node will go into HOLD mode for a
  fixed given time when switching between piconets.
• Well implement routing algorithms such as AODV,
  DSDV, DSR..
• Usage of wireless LAN mobility model.

Environment CAD Tools

• Network Simulator OPNet- simulation platform
  based on C, and Bluetooth model developed by
  Comnet students, last semester.

Major Milestones

• Setting up the simulation environment and getting
  started DONE
• Getting familiar with the BlueTooth spec
• we got to a point that enable us to start the
  implementation
• Implementing a mobile model of Scatternet
• we are currently working on it. We expect to
  finish this stage and start doing simulations by
  next week.
