  • 摘要: 在復(fù)雜的室內(nèi)環(huán)境中，測得的接收信號強度(RSS)值會出現(xiàn)不同程度的波動，導致無法準確地刻畫出無線信號傳播模型。為了解決這個問題，在基于Wi-Fi測距定位模型下，該文提出一種普適的粗粒度定位方法。該方法通過對測量到的RSS值進行擬合，以此獲取信號的傳播模型；在此基礎(chǔ)上計算出未知節(jié)點與接入點(AP)的距離，再利用天牛須算法實現(xiàn)未知節(jié)點定位，通過仿真驗證此傳播模型的性能以及該優(yōu)化算法的有效性。
    Abstract: In complex indoor environment, the measured Received Signal Strength (RSS) values will fluctuate in different degrees, which lead to inaccurate characterization of wireless signal propagation model. To solve this problem, a universal coarse grained localization method is proposed based on the Wi-Fi ranging location model. This method gets the signal propagation model by fitting the measured RSS value. On this basis, the distance between the unknown node and the Access Point (AP) is calculated, then the location of the unknown node is realized by the beetle antennae search algorithm. The performance of the propagation model and the effectiveness of the optimization algorithm are verified by simulation.
