The Centroid Wireless Localization Algorithm of Area in Underground Mine Based on TWA

摘要

In view of the request of wireless accurate position of workers and equipments, the characteristics of wireless signal transmission and position have been analyzed. Based on the Two Way Arrival and Symmetric Double Sides Two Way Arrival, a multi-Access points Centroid wireless Localization algorithm of area was designed in this paper. And The simulation shows that this algorithm performance is stable, reduces the spread and a range of error by NLOS and can improve the degree of wireless Localization accuracy in underground.
