摘要
随着社会和技术发展的需要,无线定位问题,无论室外定位还是室内定位,都越来越受到人们的重视,GPS定位系统在室外具有良好的性能,但由于建筑物遮挡,GPS不能进行室内定位,而且定位成本过高。射频识别(Radio Frequency Identification,RFID)应用于室内定位和小范围内低成本定位,表现出良好性能。RFID和其他技术相结合,例如:图论、树、模糊数学、概率论等,产生了很多相关的定位算法,该文主要论述了RFID定位问题及其与其他相关的技术结合形成的各种算法,并结合RSS与TDOA定位思想,提出一种新的定位思想,利用多个接入点接收到的RSS信号差值对目标物体进行定位,并讨论了WIFI网络和Ad-hoc等网络中的定位问题。
With the social and technological development, wireless positioning, whether outdoor or indoor location positioning, are more and more has been paid attention, GPS positioning system with good performance in outdoor, but because the building block, GPS positioning can not be positioning indoors and positioning high cost. Radio Frequency Identification (RFID) applying to indoor and smallscale, low-cost location, makes good performance. RFID combined with other technologies, for example: graph theory, trees, fuzzy mathematics, probability theory, etc., produces many relavent positioning location algorithm, this paper discusses the RFID positioning and integrating with other related to technologies forming of the various algorithms and furthermore discuss the location in WIFI network and Adhoc network.
