Abstract
Methods and apparatus for locating a network device relative to other network devices are useful for the management of wireless computing networks. Signal strength in a wireless network is indicative of a distance between a transmitting device and a receiving device. Through use of triangulation of the received signals at multiple receiving devices, the relative location of the transmitting device can be determined. Methods of refining the estimation of the expected location of the transmitting device are further provided. Defining an absolute location for at least one of the devices will permit determining the absolute location of the remaining devices based on these relative locations. Locating network devices relative to each other facilitates identifying a closest available resource within the network.
