Motivation

• Develop advanced technology solution to address the safety issues raised in our community.

• Develop accurate localization technique to cover both indoor and outdoor location details of users

Recap From the last presentation• Background Study

Current commercialized products do not have indoor localization capabilities

Patents do not present cost-efficient or accurate enough solution to indoor localization

• Challenges

Triangulation Issues:

Not enough access points to do triangulation. Inaccuracy due to signal strength and multipath Propagation.

Initial Implementation Methodology

• Transferring data from Android phone to Matlab • Instrument Toolbox to receive the data• Under Investigation• Database and server information sharing• Kalman Filters and error correction

Challenges

• Server overloaded with real-time data• Initial android application algorithm not

providing accurate data due to clock sync problem

Conclusion and Next Step • Good Result#1:• Able to send data from android in real time• Able to receive the data directly in Matlab

• Unsolved Problem #1:• Apply the theoretical algorithm in Matlab to compute

the position
