Abstract: The present invention provides a method for time synchronizing one or more devices in a control network using a first device. The method comprises selecting a first device from information of the topology of the control network. The method further comprises sending a first set of packets to the second device, receiving a first set of delay requests in response to the first set of packets, and sending a first set of delay responses in response to the first set of delay requests. The method further comprises, determining a first set of forward times and first set of backward times. The method further comprises, determining a first minimum forward time and a first minimum backward time. Further the method comprises determining a first correction factor. The method also comprises, applying the first correction factor to a clock provided at the second device and storing the first correction factor.

Abstract: The present invention provides a system and method for advising wireless computer networks on inter-network interferences during their life time. The method of the present invention initially observes initial channel utilization profiles along with corresponding time-slots of dynamic network elements and network characteristics of a first network and stores as historical channel utilization profiles. The initial transmission profiles an interfering second network are also recorded. The threshold transmission profiles are then recorded as historical transmission profiles. The aggregator determines interference patterns, by comparing historical channel utilization profiles with runtime threshold transmission profiles and advises and pre-warns appropriate network actions to a network manager of the first network on the interference prone zones. The system of the present invention includes a first network with a common multi-network interference observer, to advise on inter-network interferences.
