| Super Low Power MAC with Asynchronous Duty Cycling for Wireless Sensor Networks |
|
We designed an energy-efficient asynchronous duty cycle MAC for wireless sensor networks. Energy comsumption at both senders and receivers have been significantly reduced with efficient handling of clock drifts and hidden nodes.

| Low Latency Multihop Forwarding in WLAN |
|
We designed a low latency MAC that enables low latency multihop packet forwarding in WLAN. This MAC also improves network throughput in saturated networks.

| Multihop Broadcast in Wireless Sensor Networks |
|
We designed an efficient multihop broadcast procotol over asynchronous duty cycle MAC, called ADB, for wireless sensor networks. ADB achieves close-to-optimal latency, very low energy consumption and high packet deliver ratios.

| Asynchronous MAC Protocols for Wireless Sensor Networks |
|
We developed an asynchronous duty cycle 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 synchronous duty cycle 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 have 28 US patents pending, most of which are designed to improve throughput, fairness and QoS of coexisting WLAN and Bluetooth technologies. Some of the ideas have been or will be used in the very popurlar smart phones:).

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