Lu, Joan, Long, Hua, Xu, Qiang and Lei, Qian (2013) A New RSSI-based Centroid Localization Algorithm by Use of Virtual Reference Tags. In: The Third International Conference on Advanced Communications and Computation. INFOCOMP 2013 . IARIA, Lisbon, Portugal, pp. 122-128. ISBN 978-1-61208-310-0

A good design of node location is critical for efficient
and effective wireless communications. This paper presents an
improved algorithm, in order to solve the low localization
accuracy caused by traditional centroid algorithm. The
improved algorithm combined with VIRE system and
traditional centroid algorithm. The VIRE algorithm is
introduced and the signal propagation model is utilized to
construct virtual reference tags in the location area. Simulation shows that this further developed algorithm has further improved the accuracy of positioning up to 35.12% compared
to the traditional centroid algorithm. It is concluded that this algorithm can further improve the locating accuracy in comparison with the original centroid algorithm.
