A method of constructing an approximate spatial representation of electronic devices in a neighborhood of devices is described. The method may include collecting data from electronic devices within a range, wherein the data comprises one or more of a unique identifier for an electronic device, endpoints of original electronic devices, and level of indirection of a discovered endpoint and building a data collection representing a neighborhood of electronic devices from the collected data. The collected data may further include relative distance or received signal strength indication or other information about physical location of the electronic device.
