学术讲座通知应我校信息与通信工程学院信息理论与技术教研中心责任教授林家儒邀请，美国爱荷华大学的吴智君教授将于2010年12月10日访问我校并作精彩学术报告。欢迎我校师生踊跃参加。报告题目：A Direct Geometric Method for Sensor Network Localization 主讲人：Professor Zhijun Wu （Department of Mathematics,Iowa State University, USA）主持人：罗新龙副教授时间：2010年12月10日（周五）下午4:00-5:00 地点：教三楼811会议室报告摘要:：We present a geometric buildup algorithm for solving the sensor network localization problem with either accurate or noisy distance data. The algorithm determines the locations of the sensors, one at a time, by using the distances etween the determined sensors and the undetermined ones. Each time,only a small system of distance equations needs to be solved and therefore,in an ideal case when the required distances are available for every sensor to be determined, the computation can be completed in n steps if n sensors are to be determined. An algorithm with two buildup phases is also implemented to handle not only noisy but also sparse distance data with for example only a few distant anchors. We show our test results and compare them with other approaches. 此报告为前沿讲座，欢迎全校师生踊跃参加。校学术委员会信息与通信工程学院 2010年12月6日
