Introduction l.jpg
Introduction

  • Cricket Compass

    • Determine the orientation and location indoors

    • Active beacons, passive sensors, and associated software algorithms

Beacons on

ceiling

RF + Ultrasonic

Pulse

Cricket listener

with RF and ultrasonic

sensors

Mobile device


Problem definition l.jpg
Problem Definition

  • Using many beacons in large place causes much cost and interference between them

Interference can be happened


Motivation l.jpg
Motivation

  • Reducing the number of beacons while covering all area in the building

Applying ad-hoc network to the cricket compass


Approach l.jpg
Approach

  • Devise a novel protocol for the Cricket Compass, Enhanced Cricket Compass

  • Make a simulation so as to show how many beacons can be reduced using ns2

  • Schedule

    • ~ 10. 14 : survey more about the existing cricket compass

    • ~ 11. 11 : devise a novel protocol

    • ~ 12. 9 : make a simulation and report
