Patent ID: 7580711

Claim:
A method to create a topology map of a wireless network, wherein said wireless network includes a plurality of network devices, wherein said network devices include mobile network devices provided for direct wireless communication in-between each mobile network device, and wherein said topology map indicating the quality of connectivity of each of said plurality of network devices with all other network devices of said plurality of network devices, comprising: performing a measurement phase in which a calibration signal is successively broadcasted by each network device and in which all respective other network devices receiving said calibration signal directly from a broadcasting network device measure the received signal quality; performing a reporting phase in which a reporting control signal is broadcasted by a network device creating said topology map to each other network device and in which the measurement results are directly wirelessly transmitted from each other network device receiving said reporting control signal to the network device creating said topology map; performing a creating phase in which said topology map of the network is created within the network device creating said topology map solely on a basis of all received measurement results; and performing a transmission phase in which said network device creating said topology map transmits at least part of said topology map to the other network devices.
