Claim Text:
1. A method for determining a topology of a wireless communication network, the method comprising: receiving, by a topology generating device from a plurality of fixed stations, a plurality of signal strength data respectively measured at the plurality of fixed stations in the network each with respect to its neighbouring fixed stations; receiving, by the topology generating device, sensor data measured at a mobile station operable to communicate with the network, wherein the sensor data comprises signal strength data measured at the mobile station and at least one of an acceleration data, an orientation data, a direction data, and a mobile station position data; determining, by the topology generating device, positions of the plurality of fixed stations based on the signal strength data measured at the plurality of fixed stations and the sensor data measured at the mobile station; and determining the topology by estimating at least one of a distance and a direction, using the at least one of acceleration data, orientation data, direction data, and mobile station position data, between two or more locations of the mobile station at which signal strength data has been measured, to reference the positions of the plurality of fixed stations with respect to an absolute reference frame.
