Our research explores the theories, methods, and systems building-blocks for addressing dynamics and uncertainties in networked systems that involve wireless networks, sensor networks, embedded networks, and the Internet. Presently, we are especially interested in the modeling, algorithmic, and systems issues in wireless, vehicular, sensor, and embedded networks. For instance, as a part of the NSF CPS program and in collaboration with USDOT/SAIC, we investigate field-deployable mechanisms for reliable, real-time, and secure wireless networking, and we investigate cross-layer approaches to taming cyber-physical uncertainties in wireless networked sensing and control; as a part of the NSF GENI program, we develop the theoretical and systems foundations for experimentation and service provisioning in federated, networked sensing. Besides publications, our work has provided foundational components for several wireless network systems, including the WiMAX research network, the KanseiGenie federated sensor networks, the NetEye experimental infrastructure (which has 176 IEEE 802.15.4 nodes and 15 802.11b/g nodes), and the DARPA sensor network systems A Line in the Sand and ExScal (which, with its 200-node 802.11b mesh network and 1,200-node mote network, was the world's largest wireless sensor network and 802.11b mesh network deployed at its time). For a brief introduction to wireless cyber-physical systems and wireless sensor networks, please check out this short video and presentation. |
