    Mobile Data Gathering in Wireless Sensor Networks
    Update time: 2011-06-22

    Speaker: Prof. Yuanyuan Yang, Stony Brook University, New York, USA
    Time: 09:30am—11:00am, June 27th, 2011 (Monday)
    Place: Meeting Hall, 4th Floor, ICT, CAS
    In this talk, we consider a wireless sensor network that consists of a large number of sensors and a limited number of mobile data collectors. In such a network, mobile collectors take over the burden of routing from sensors, roaming over the sensing area and collecting data from nearby sensors via short-range wireless communications. We present a series of efficient mobile data gathering schemes in such sensor networks, which aim to prolong network lifetime and shorten data gathering latency.
    1、Moving path planning with multi-hop relays.
    2、Single-hop data gathering.
    3、Mobile data gathering with controlled mobility and SDMA technique.
    4、Bounded relay hop mobile data gathering scheme.
    Yuanyuan Yang is currently a Full Professor of Electrical & Computer Engineering and Computer Science at Stony Brook University, and the Director of Communications and Devices Division at New York State Center of Excellence in Wireless and Information Technology (CEWIT). She received her PhD degree in computer science from Johns Hopkins University, Baltimore, Maryland, in 1992. Dr. Yang's research interests include interconnection networks, wireless/mobile networks, optical networks, high-speed networks, multicast communication and parallel and distributed computing systems. She has authored or coauthored more than 230 research articles in leading refereed journals and conferences with over 60 papers published in IEEE Transactions on these topics. She is also an inventor/co-inventor of six U.S. patents in the area of interconnection networks.
