Before revision:  In this paper, we also attack the unit disk recognition problem on a restricted domain, by assuming a scenario where the wireless sensor nodes are deployed on the corridors of a building , forming collinear groups . Based on this scenario, we impose a geometric constraint such that the unit disks must be centered onto given straight lines.
