  In applications such as seismic acquisition, the position information of
sensor nodes, that are deployed in a linear topology, is desired with sub-meter
accuracy in the presence of a limited number of anchor nodes. This can be
achieved with antenna arrays via mm-wave cooperative localization, whose
performance limits are derived in this letter. The number of anchor nodes is
seen to have a stronger impact than the number of antenna elements in the
anchor nodes. Succinct closed-form expressions for the position error bound are
also obtained for 1-hop and 2-hop cooperative localization, where sub-meter
accuracy is perceived over several hundred nodes.
