摘要

Wireless indoor communications, the mobile robot tracking is the one of application in wireless sensor networks (WSNs). A one of promising localization algorithm in range-free algorithm is the weighted centroid algorithm (WCA). This work proposed the improved WCA with quadratic means based on received signal strength (RSS). The ZigBee operated at 2.45 GHz frequency was used to measure in the indoor environment. The results are discuss about the comparison of the typically WCA and the improved WCA. From the results, The 1 m. precision of improved WCA is 92% and WCA is 83%. Besides that, the improved WCA obtained the 17% no error estimated position.
