Most localization algorithms in wireless sensor networks
rely on a few reference nodes with known locations
to estimate the locations of unknown nodes. The locations of
reference nodes can be either manually configured or, more
practically, obtained by means of some satellite-based positioning
system(s). However, satellite-based locations may be inaccurate
and imprecise, which results in reduced location accuracy of
localization algorithms. This paper proposes a peer-to-peer
cooperative GNSS-based localization algorithm for stationary
reference nodes to improve their relative location accuracy and
precision. The algorithm applies simple statistical methods and
GNSS-based information from multiple reference nodes within a
WSN in a peer-to-peer fashion to achieve the improvement. The
results of the experiments indicate that both location precision
and relative location accuracy are clearly increased due to the
algorithm.
