【摘要】:當(dāng)前基于RFID的定位系統(tǒng)無法使用異構(gòu)移動(dòng)閱讀器按照分布式策略定位移動(dòng)標(biāo)簽,且定位精度低下。針對這種情況,提出了LSMT-RFID系統(tǒng)。該系統(tǒng)使用一組異構(gòu)移動(dòng)式RFID閱讀器來定位移動(dòng)RFID標(biāo)簽,移動(dòng)閱讀器通過時(shí)間約束交錯(cuò)過程展開合作,附近的閱讀器通過共享詢問信息來相應(yīng)地估計(jì)標(biāo)簽位置,并使用主動(dòng)和被動(dòng)協(xié)議來確保位置信息的及時(shí)傳輸;趎s-3的仿真實(shí)驗(yàn)來評估方案的定位能力,重點(diǎn)考察了平均定位誤差和定位延時(shí)。實(shí)驗(yàn)結(jié)果表明,本方案能實(shí)現(xiàn)有效定位。
[Abstract]:The current location system based on RFID can not use heterogeneous mobile reader to locate mobile tags according to distributed strategy, and the positioning accuracy is low. In view of this situation, the LSMT-RFID system is proposed. The system uses a set of heterogeneous mobile RFID readers to locate mobile RFID tags. The mobile readers cooperate with each other through the interlacing process of time constraints. Nearby readers estimate the location of the tags by sharing query information. Active and passive protocols are used to ensure the timely transmission of location information. The simulation experiment based on ns-3 is used to evaluate the localization ability of the scheme, and the average positioning error and the location delay are investigated. Experimental results show that this scheme can achieve effective positioning.
