1. Network Coding Testbed
Jeremy Bergan, Ben Green, Alex Lee

2. Network Coding Overview
Network Coding: Combine and forward packets to increase throughput
Data is combined at intermediate nodes
Decoded at later nodes or at the client
Analog Network Coding: Combine wireless signals through interference to increase throughput
Decode combined signals at the client
Intermediate router amplifies and forwards signals

3. Network Coding Model

4. Requirements   
Implement a Network coding scheme with equal or better throughput than traditional networks
Improve upon previous research
Analog Network Coding
Practical application to arbitrary network topologies
Use of Universal Software Radio Peripheral (USRP)
Use of GNU Radio signal processing libraries

5. Constraints Time to Implement System Complexity
System Complexity
Tied to Specific Hardware and Software
2.4 GHz GHz spectrum 
limited data transfer rate
Processing Power
Software Defined Radio moves signal processing to general purpose CPU, lots of data and limited CPU cycles

6. Schedule

7. Cost Estimate
7 USRPs (Universal Software Radio Peripheral) in the lab.
7 more USRPs ordered.
All softwares are stored and installed in the computer.
All necessary hardware and software is already owned by the university.
