Major Research Areas
Research Summary
1.Cognitive wireless networks: Next generation radios are capable of utilizing unused spectrum opportunistically, subject to regulatory restriction. To fully exploit such capability, communicating ratios must discover unused spectrum and coordinate their use of spectrum without interfering the licensed radios. This research will focus on the design of cross MAC- and PHY-layer spectrum-sensing mechanisms and new MAC protocols to enable cognitive wireless communication. The protocol will be validated via theoretical analysis and simulation, and will be implemented using off-the-shelf radios to demonstrate the performance.
2.Multi Gigabytes wireless transmission: Emerging applications such as high definition (HD) video streaming and fast file transfer require at least multi-gigabyte bits-per-second wireless links. Ultra-wide-band (UWB) and millimeter-wave technologies can provide such extremely-high PHY-layer rates but suffer from throughput inefficiency or short transmission range. This research will investigate various techniques, such as directional network protocols, to address these issues. Such techniques could be integrated with GICE’s millimeter-wave RFs to provide full-system multi-gigabyte solutions
3.Cooperative transmission: Cooperative transmission requires a third device, called a relay, to participate in the transmission between the source and destination. It has been shown that by properly encoding and combing transmissions from the source and the relay, the destination device can obtain a spatial diversity gain without using multiple antennas. This is very useful for low-cost wireless devices as in general they are limited in size and battery capacity. This research addresses the issues from the MAC layer’s perspectives. Light-weight handshaking mechanisms and relay selection will be developed so that the cooperative transmission is “activated” by participants in an autonomous manner.
4.Scalable sensor networks: Sensors are widely used in manufacturing automation, building management or medical applications such as patient monitoring. These sensors may form a huge network with thousands of nodes, which eventually will suffer from reliability or scalability issue. This research will investigate these issues and develop a scalable wireless sensor network for various applications.
