Approximate information on the location of nodes in a sensor network
is essential to many types of sensor network applications and
algorithms. In many cases, using symbolic coordinates is an
attractive alternative to the use of geographic coordinates due to
lower costs and lower requirements on the available location
information during coordinate assignment. In this paper, we
investigate different possible methods of assigning symbolic
coordinates to sensor nodes. We present a method based on
broadcasting coordinate messaging and filtering using sensor events.
We show in the evaluation that this method allows a reliable
assignment of symbolic coordinates while only generating a low
overhead.
