Project WIN : WIRELESS INTRANET Daniel Gardner & Jeeth Suresh ECE445 SP16 Group #1 TA: Jamie Norton

ABOUT 60% OF THE HUMAN RACE DOES NOT HAVE INTERNET There’s no infrastructure Communication infrastructure isn’t justified for communities without a significant economy Data plans are expensive Data plans cost over $50/month in remote areas, if even offered WiFi devices are useless WiFi-enabled devices, donated through organizations such as One Laptop Per Child, are relatively useless without a wireless network

OUR SOLUTION: A WiFi-BASED INTRANET Apps are independent from the internet Sustainability is a necessity Hotspots will allow for access within 800 feet Our goal is an educational network Not limited by electricity infrastructure, battery- powered at night for constant connection. Affordable for a subsistence farmer. Solar-powered Educational resources such as Wikipedia and Project Gutenberg will be hosted on the network Hosted education Store 16GB of resources and link into the network via WiFi, eliminating the need for the global internet to access resources Node hotspots Nodes will provide communication services such as instant messaging and e- mail Hosted web apps Central connection to cellular network

+1.7% Increase in exports (10% adoption) $3,703 Average GDP of developing nations +1.1% Increase in imports (10% adoption) Sources: Brookings, UNCTAD

$227 BILLION Projected increase in the world economy following a 10% increase in third-world internet access

REQUIREMENTS Power Nodes must be able to provide at least 150mA at 3.3V constantly on 10 hours of direct sunlight per day Integration Microcontroller must be able to host stored data over the network at over 100kbps without any other limiting factors Uptime The network must be self-healing, properly adapting to a node failing. Nodes must gracefully find a new path on which to send data to the required node in less than five seconds (the total time spent finding a new path is < 5s) Durability Nodes must be able to withstand torrential downpour and a 1m drop Networking Packets must traverse the network through nodes at a rate of no less than 100kbps Affordability The price must be affordable for a low-income family - no more than $25USD/node and no more than $100USD/server
