1. SMART WIRELESS ROUTER ECE 445, Senior Design, Fall 2015 Project 2 Devasia Manuel Christopher Reinke TA: Eric Clark

2. Introduction Smart Router – Block ads – Page cache – Home automation

3. Goals and Objectives Goals Provide a smart home experience through the ZigBee devices. Provide useful client side services to connected devices. Benefits Improve the mobile experience by providing page- caching and ad blocking services to connected devices Allow the user to interact and control various ZigBee devices

4. The Smart Wireless Router

5. Design of Project Hardware : Antennas, Raspberry Pi2, Zigbee circuit, Power Supply, LCD Touch screen Software Ad Block Page-caching User Interface ZigBee Control Software

22. Software – ZigBee + Home Automation Open source wireless technology that enables ‘Smart’ devices Usually controlled through an Android/iOS app Goals Integrate into Samsung SmartThings Allow other ZigBee products to interface with our router

23. Software – ZigBee Examples

24. Software – Interfacing with SmartThings Samsung Cloud Zigbee GE Link Lightbulb Samsung LED

25. Software – ZigBee Control Software

26. Software – ZigBee Verification Samsung Cloud Zigbee GE Link Lightbulb Samsung LED

27. Software - Ad Block Intro Before After

28. Software - Ad Block Flow Chart

29. Software - Ad Block Verification Connected to ‘IllinoisNet’ Connected to ‘adfree_wifi’ Tested across mobile devices, mobile apps, desktops and laptops

30. Software - Page Caching Intro Cache content on router Speed up load times

31. Software - Page Caching Flow Chart

32. Software - Page Caching Verification

33. Conclusion Everything worked! Some flaws: – Page-caching doesn’t work for HTTPS – Antenna accuracy

34. Future Improvements Make it smaller Make page caching faster. More accurate 2.45GHz frequency antenna for less packet drops. Have companies work with us so we can develop directly for their platform.
