coplanarity. In most real-world applications, even though the environment is 3D, the
grounded sensor nodes are usually deployed on 2D planar surfaces. Examples of these
surfaces include structures seen in both indoor (eg floors, doors, walls, tables etc.) and
outdoor (eg mountains, valleys, hills etc.) environments. In such environments, sensor nodes
typically appear as coplanar node clusters. We refer to this type of a deployment as a planar …
