Weighted centroid localization for wireless sensor networks

Abstract

Localization is essential in the field of wireless sensor networks (WSNs). Compared to other non-interactive localization algorithms, the weighted centroid localization scheme only uses the information of the received signal strength (RSS), which makes it simple to implement and robust to variation in the propagation environment. In this paper, we propose an improved weighted centroid localization algorithm based on RSSI for an indoor localization. Real experimental results show that IWCL-RSSI is better than WCL (weighted centroid localization) in terms of the localization accuracy.
