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

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

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

The Smart Wireless Router

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

Block Diagram for Hardware The electrical components of this project consist of three main parts: user interface, control system, RF and power unit. of three main parts: user interface, control system and power unit.

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

Software – ZigBee Examples

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

Software – ZigBee Control Software

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

Software - Ad Block Intro Before After

Software - Ad Block Flow Chart

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

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

Software - Page Caching Flow Chart

Software - Page Caching Verification

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

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.
