A Kind of Improved Triangle Centroid Algorithm Based on RSSI-Ranged

Abstract

Node self-localization is one of the key technologies in the wireless sensor networks. The localization technology based on RSSI is a focus studied at the present stage. For the localization error of RSSI-ranged method is relatively great, a kind of triangle centroid algorihms based on RSSI-ranged is proposed. The simulation results show that measurement error of this algorithm effective decrease as to tranditional triangle centroid algorithm based on RSSI-ranged.

An Improved RSSI Location Algorithm Suitable for Digital Workshop

“…Great breakthrough has made in the process of study RSSI location algorithm, some scholars focus on the combination RSSI with other algorithm [1,2]; and some scholars prefer to study the number and arrangement of anchor nodes [3,4]; many professors make their efforts to use filtering method to reduce the fluctuation of the RSSI value [5,6]; and also many graduate introducing Centroid of the triangle principle to Improve the positioning accuracy [7,8].…”
