题 目 Localization for Wireless Sensor Networks

报告人 何田教授，美国明尼苏达大学

摘 要

    Wireless Sensor Network (WSN) systems have been used in many promising applications including military surveillance, habitat monitoring and wildlife tracking. While many middleware services to support these applications have been designed and implemented successfully, node localization - finding the position of a sensor node -remains one of the most difficult and important research challenges to be solved in practical settings. In this talk, we explain first why the existing range-based and range-free localization methods are inadequate to meet low-cost and high accuracy requirement simultaneously. To address this limitation, we present several localization techniques which achieves high accuracy with low cost. The limitations and advantages of these new technologies shall be discussed during the talk.
