学术讲座通知讲座题目：The Internet of Things Goes Wireless 主讲人：Mischa Dohler（西班牙CTTC的资深专家）时间：2009年10月21日（星期三）下午3:30-5:00 地点：教三楼317 内容简介：Designing WSNs is not a one-layer exercise anymore; a sufficient knowledge of all factors impacting the system performance is hence vital. The objective of this tutorial is to acquaint the academic and industrial audience with important design and analysis tools needed to optimize and deploy WSNs. To this end, the following will be discussed in the three parts: In the first part, we will discuss the cradle of WSNs and the reasoning of their emergence around a decade ago. We will also dwell on their commercial importance, i.e. business projections, commercial activities worldwide, etc. This part will be finished by detailing current standardization approaches, including WOSA, KNX, IEEE 802.15.4, IETF 6LoWPAN, IETF ROLL, etc. The second part is dedicated to node and network design. We will commence by detailing the peculiarities of the WSN channel. This in turn will dictate the PHY design, which is discussed thereafter; in particular, we will discuss the choice of hardware, modulation, whether channel code is needed, some distributed signal processing algorithms, etc. Thereafter, we will dwell on energy-efficient medium access control protocols; in particular, we will discuss latest approaches in preamble-sampled based MACs as well as MACs which do not need to maintain any information on the one-hop neighbourhood. We then move on to fault-tolerant and energy-optimized routing protocols, as well as self-organizing and self-healing sensor network mechanisms, etc. The importance of cross-layer design, localization determination and security with their available techniques will finally be exposed. The last and final part deals with practical experimentations ranging from in-house experiments (http://www.youtube.com/watch?v=q6_2gtMf03w) to commercial roll-outs (e.g. Coronis/Elster). There will be time for questions and discussion. 此讲座为前沿科技讲座，欢迎全校师生踊跃参加。校学术委员会信通院 2009年10月11日
