Abstract
Localization technology has been attracted a lot of attention for viewed as one of the core technologies of wireless sensor networks, among which RSSI localization technology is widely used given its advantages in easy accessibility and low cost. The paper analyzed the RSSI localization technology and proposed a RSSI measurement-corrected weighted centroid localization algorithm on the basis of the traditional centroid localization algorithm. The distance was measured by RSSI and was corrected by the reckon method of centroid; the localization was completed by the weighted centroid localization algorithm which has been corrected. The simulation results show that, compared with the traditional localization algorithm, the modified algorithm proposed by this paper shows significant improvements on positioning accuracy.
