| 题目：Sink-Anonymity Mobility Control in Wireless Sensor Networks 报告人：Dr. Xiao Chen, Texas State University 时 间：2009 年1 月7 日（周三）上午10:00 地 点：蒙民伟楼 109 会议室 摘 要 With the development of technology, wireless sensor networks (WSNs) performing sensing and communication tasks will be widely deployed in the near future because they greatly extend our ability to monitor and control the physical environment and improve the accuracy of information gathering. Since the sensors are usually deployed in hostile environment and cannot get recharged frequently, the power in sensors is the scarcest resource. Recently, attention has been drawn to using mobility control to minimize energy consumption in wireless sensor networks. However, the existing schemes suffer from slow convergence and oscillation. In our research, we put forward quick convergence mobility control schemes without oscillation. We also identify a novel privacy issue: sink location privacy in our schemes and propose sink-anonymity schemes to protect the sink. Analysis of the schemes shows their effectiveness in sink protection. The schemes can be well integrated into our mobility control protocols to enhance their security. 简 历 Dr. Xiao Chen is an associate professor of computer science at Texas State University.
