Brief Biography

Weidong Xiang received his M.S.E.E. and Ph.D. degrees from Tsinghua University, Beijing, China, in 1996 and 1999, respectively. From 1999 to 2004 he worked as a post-doctoral fellow and then a research scientist at the Software Radio Laboratory (SRL) at Georgia Institute of Technology, Atlanta. In September 2004, he joined the ECE Department, University of Michigan-Dearborn. His research interests include vehicular communications and networks, LTE, UWB, smart grid and wireless networked control system.

Research Highlights: xRadio-An Easy Software Defined (SDR) Radio Platform for Internet of Things and Connected Vehicles

xRadio is an easy software defined radio (SDR) platform for fast prototyping of various emerging wireless systems featuring with attracting cost-performance ratio when compared to current solutions. xRadio achieves its advancement and integrity through adopting a compact and right-on-target design strategy, consisting of a cost efficient minicomputer, raspberry PI, or a field programmable gate array (FPGA) chip from Altera as its core processors. Function modules can be easily realized through C/C++/python programs in a Linux environment or programmable logical elements (LEs) of FPGA achieving powerful computation. xRadio is created to remove the technical barriers and flatten the learning curve associated with developing advanced/customized wireless platforms for a board range of applications ranging from research, engineering and education. xRadio is affordable and easy to use for developers from researchers, engineers and students. xRadio has potential to be applied in the areas of Internet of Things, connected vehicles, smart grid, eHealth and many others. Furthermore, xRadio integrates flexible interfaces to Raspberry PIs, computers and Android/iOS smart phones.



Research Highlights: A Large Scale High Fidelity Autonomous and Connected Vehicle Emulation Platform

Emerged as an indispensable element of modern society, autonomous and connected vehicles is expected to be widely deployed worldwide largely enhancing the safety on the roads and initiate
new intelligent transportation system (ITS) applications to respond to the increasingly severe transportation environments globally, as well as reshape the way we drive and ride in the near future through their pervasive product penetration. Given the high impacts of such a nation wide road information infrastructure, there is no shortage of ideas in academia and industry about approaches, technologies, and applications for realizing and using vehicular communications and networks. Yet, progress in realizing these ideas is stifled by the difficulty in validating them: testing them in real world settings is fraught with logistic, financial, and safety issues, whereas testing them in a sterile, simplified simulation environment inherently misses some of the complexities and risks associated with such a complex ITS system. However, large-scale experiments have to be limited to track track and hard to be reproduced in different cities and roads in Southeast Michigan. To response to this critical need, A Large Scale High Fidelity Autonomous and Connected Vehicle Emulation Platform is proposed to allow researchers and engineers in related areas to evaluate models, algorithms and protocols based on physical hardware and actual signals in a near realistic and controllable environment, which is the objective and motivation of this effort.
