Group 10: wvU- Secure Final Presentation 24 April, :00 P.M. ESB 801
Background Incarnations of security systems have existed for centuries Each generation adds more security Modern systems are more advanced than ever
Modern Systems Features: remote monitoring of home dialing owners/authorities (recently) smartphone integration Can require any of the following: costly installation by a professional monthly subscription fees a landline for calling
Original Problem Statement Develop a system to remove most requirements No professional installation required No subscription fees No landline required Implement smartphone integration
Overall Architecture
Final Project Status Completed approximately 80% of original goals Major Time Alterations/Delays Raspberry Pi / TinyOS Installation Sensing Application Android Development Client/Server Communication Goals Abandoned Glass Break Sensor Non-local client/server communication Do have functioning security system
Raspberry Pi / TinyOS Installation ARM Processor!!! TinyOS - Open Source - Not developed for ARM
Sensing Application Interfaces with Telos B ADC Initializes antenna/radio transmitter Broadcasts sensor data
Android Development Android SDK Multithreaded Design: User Interface Background Process: TCP Client
2-Way Communication First attempt at server-client communication Sockets: local IP, Port Multiple input listeners: one for Android, one for sensors Texts via Google Voice API
Glass Break Sensor Abandoned Due to Time Focus was on getting working system Originally had goal to fabricate Learning Curve > Time Available
Non-Local Communication Opted for local-only message passing Budget/time constraints Not very practical Alternatives: 3 rd party server or router configuration
Conclusions Functioning Security System Strengths Is more informative than other Systems Gives User more control Instant Notification No Monthly Fee Low initial cost - (appx. $300) Weaknesses Only limited sensor options Detailed Set-up of Linux PC (not practical for production)
