Abstract: There have been increasing interests in deploying wireless sensors in three-dimensional (3D) space for such applications as underwater reconnaissance and atmospheric monitoring. An individual sensor is highly resource-constrained, with extremely limited computing, storage, and communication capacities. To network a large number of such sensor nodes is challenging. Particularly, compared with its 2D counterpart, the scalability problem is greatly exacerbated in a 3D sensor network due to dramatically increased sensor quantity in order to cover a 3D space. This talk will introduce several recent findings aiming to support efficient data communication in 3D wireless sensor networks. A key strategy of the proposed solution is to preprocess the global network information via a distributed algorithm, such that a sensor only needs to store a minimum amount of information to make correct and efficient local routing decisions, thus achieving scalable routing. To this end, geometric theories and tools are exploited to develop practical routing algorithms that provide guaranteed delivery, require small bounded storage, and are based on local computation only. 



Bio: Dr. Wu received my B.S. degree from Zhejiang University, China in 1996; M.S. degree in Electrical & Computer Engineering and Ph.D. degree in Computer Science from the State University of New York at Buffalo in 2000 and 2002, respectively. Since then, Dr. Wu has been with the Center for Advanced Computer Studies (CACS), University of Louisiana at Lafayette, where he was promoted to Associate Professor in Summer 2007 and awarded the Alfred and Helen Lamson Endowed Professorship in Computer Science in 2008. His current research interests focus on wireless and mobile networks, including wireless LANs, mobile ad hoc networks, wireless sensor networks, the next generation wireless systems, and integrated heterogeneous wireless & wired networks. Dr. Wu received NSF CAREER Award in 2004.
