1. Mobile phone programming
Implement an interesting application with some wireless/mobile networking component. I mentioned a distributed Bingo example.

Implement a wireless mesh networks on Linux nodes, with a server that decides various parameters, i.e., which channels each node should operate on, what should the topology look like. We will give you code to implement the optimal choices, and you have to implement the messaging between the mesh nodes and the central server, ensure robustness, etc.
3. Video multicast
How can you implement a WiFi multicast service in a single hop wireless LAN. I have a sketch of the multicast protocol and you will have to implement this, mostly at the application layer, but with some kernel and driver-level mechanisms. In Linux.
4. Client-assisted wireless management
Implement a toolkit for Windows laptops and Windows mobile devices, that will accept certain commands from a controller node and execute certain simple measurement tasks, e.g., conduct some pings, do some bandwidth tests, etc. The server will aggregate measurements from many such clients and then create a nice view of the entire network. Show this either for an indoor enterprise WLAN or an outdoor wireless mesh.
5. Energy efficiency for mobile devices
There is a specific technique for energy efficiency called the power-save mode in the 802.11 standards. However, in its current form, the latencies are high. We have a new technique that will allow each client to have low latency, and yet have power saving benefits. Will involve various low-level kernel and driver level mechanisms in Linux.
6. Video streaming from mobile phones
Implement a full live video streaming system from a Nokia N95 (Symbian) or Nokia N800 (Linux) mobile phone. Then investigate performance (throughput) and energy costs, and try to optimize them. The basic implementation of a streaming system itself will be quite interesting.
7. TCP for multi-hop wireless
TCP does not work well for a multi-hop wireless link in many cases. Conduct a detailed measurement study of TCP over a multi-hop wireless path. Explain why TCP performs poorly. Investigate wireless router based mechanisms to improve performance of TCP, that does not require any change to the clients (TCP endpoints).
8. Software-Defined Radio projects
We have access to two different SDRs. GNURadio and WARP radio (Rice University). Do a search to find more about them. There are many possible projects on this platform.
- Try to implement a radio fingerprinting technique (we have already defined a technique … you have to implement it). Come and talk to me about it.
- Try to understand performance of various wireless sub-carriers in a OFDM system. How do neighboring sub-carriers correlate in performance with each other. What does this imply on protocol design for such OFDM systems with multiple users.
- Implement some simple spectrum sensing techniques using these radios. We can mount these radios on a vehicle. As the vehicle moves about, we can collect large volumes of data on spectrum usage in different wireless bands.
- Approximate communication and multi-rate packetization (ask me about them).
- Investigate some core aspects of a WiMAX system.
9. Think of your own projects.
