1. A method comprising: capturing, by a first node device, locational signals projected by a second node device, wherein the locational signals are captured by the first node device from a capture area and projected by the second node device into a projection area bordered by an arc and having an overlapping region with the capture area, wherein both the capture area and the projection area extend beyond the overlapping region; analyzing the locational signals within the overlapping region to determine a portion of the arc of the projection area that is included within the overlapping region; using the determined portion of the arc of the projection area within the overlapping region to determine an angular relationship between the first node device and the second node device and a relative distance between the first node device and the second node device; and using the angular relationship and the relative distance to determine a location of the first node device relative to the second node device.
