报告摘要：
　　We develop a novel information model to achieve a reliable routing path in the wireless ad hoc sensor networks in which each communication link is constituted in an irregular way and its quality changes dynamically. We focus on an “everyone” model that each node will apply the same genetic process in a fully distributed manner, in order to achieve a reliable solution in dynamic networks. The key is to make each routing decision aware of the capability of non-detour path ahead so that an adjustment can be made early to avoid wasting time. Our approach adopts the proactive model and provides a relative referee to each node for different paths passing through, saving the cost and delay of reconstituting in the probing process of the reactive information model. Compared with the best results known to date, our indirect reference information is cost-effective. On one hand, without initiating any extra information process, the information is simple enough to be attached in the beacon message for the MAC synchronization. On the other hand, we find a balance point of tradeoff between the precision of interpreter of global optimization (e.g., number of hops for the entire path) and the granularity of converging region of information construction.

　　Dr. Zhen Jiang received B.S. degree from Shanghai Jiaotong University, China, in 1992, Master degree from Nanjing University, China, in 1998, and Ph.D. degree from Florida Atlantic University, U.S.A., in 2002. Currently, he is associate professor of Computer Science Department at West Chester University of Pennsylvania, U.S.A. He is also a faculty member of Information Assurance Center at West Chester University. His research interests are in the area of information system development, routing protocols, and wireless sensor networks.
Dr. Jiang’s research mainly focuses on the information modeling in wireless sensor networks (WSNs). In every area of life there is an opportunity for research and improvement with the idea of “Going Green” in mind. By providing green information techniques, Dr. Jiang’s goal is to improve the utilization of the resources in WSNs versus replacing the entire network by another deployment or at least extending the lifetime so replacement is needed less often. Sensors are tiny devices and cannot get recharged after they are deployed. The power and computational ability in each one is critically limited. An efficient and effective resource management is the key to many applications such as environmental surveillance and target detection.
Dr. Jiang’s research has been granted by many fund resources, internal and external, including National Science Foundation (NSF), IBM, CASSDA, and local FDC. Currently, he supervises two undergraduate students for a project (CCF 0936942) which is granted by Research Experience for Undergraduates (REU) program at NSF. His collaboration with more than 10 domestic and foreign universities is supported by NSF grants and is highly recognized. He was invited and currently serves as NSF panelist, external reviewer for Hong Kong Research Grant Council, and panelist for the office of Global Environment for Network Innovations (GENI). He is the Ph.D. advisor committee member for Lisa Mathews at Old Dominion University and the external reviewer for tenure and promotion at Missouri State University. He is the area editor on wireless security for International Journal of Ad Hoc & Sensor Wireless Networks and MASAUM Journal of Computing. He was often invited to give talks, including the recent seminar talk given at City University of Hong Kong on February 25th 2010.
Dr. Jiang is also active in many committees. He involved in the organization of many IEEE conferences and workshops, including the recent IEEE MASS 2010 as the finance and registration chair. He serves technique committee for more than 20 IEEE conference and workshops. He is invited to review technique papers for more than 10 journals. He is a member of IEEE.
