Project Implementation Details
This project can thought of as two parts, the control at device level and the management at the deployment level. Ilsun Lee's thesis is focused on the communication and control of the individual routers while Yuxiang Liu's thesis is focused on the management of a deployment of routers. While we may focus on different parts of the project, we still collaborate very closely on the implemenation of the project. By combining our strengths, we are able to implement a more complex project then what we could have done individually.

The Device

The device that we are modifying to implement our project is the Netgear WGT634U Wireless Storage Router. This device has many useful features that we used to make our project implementation easier. First it runs on a modified Linux 2.4.20 kernel so we don't need to worry about programming in a different environment. Second, it uses a Atheros 802.11b/g WIFI card, which has a very well written open source network driver MADWiFi, so we are able to add our extensions to the network driver easily.
How it works
The wireless card in the router overhears all wireless traffic within its range and moves the packets to the MADWiFi network driver. The network driver then adds some statistics the such as the received signal strength index (RSSI) to each packet. Each packet is then routed to the Click Modular Router which transmits the header information and the RSSI to the client program on the router via IPC. The client program aggregates the data and transmits a summary of the packets that was received to the server every minute.
