| My recent work on wireless networking |
| Asynchronous MAC Protocols for Wireless Sensor Networks |
|
We developed a new asynchronous MAC protocol, called Receiver Initiated MAC (RI-MAC), that achieves high throughput and energy efficiency under a wide range of traffic loads. RI-MAC has been implemented both in TinyOS on MicaZ and in ns2 simulator.

| Synchronous MAC Protocols for Wireless Sensor Networks |
|
We developed a new MAC protocol, called Demand Wakeup MAC (DW-MAC), that achieves low delivery latency under a wide range of traffic loads including both unicast and broadcast traffic.

| Coexistence of Wireless LAN and Bluetooth technologies |
|
We've filed seven patent disclosures to improve throughput, fairness and QoS of coexisting WLAN and Bluetooth technologies.

|
| MAC Protocols for Wireless Mesh Networks |
|
We developed a new MAC protocol to take advantage of the superposition coding feature provided by physical layer.

| Simulation of Large-scale Wireless Networks |
|
We have improved the ns-2 simulator so that it is able to support network simulations with more than ten thousand mobile nodes.
