Patent number: 8862430Abstract: There is provided a method for estimating a position of a mobile node in a wireless sensor network. The method includes estimating a frequency offset between anchor nodes and estimating a difference between times when ranging frames from a mobile node are received by two anchor node, without use of a separate synchronization unit, such as a network synchronized clock supply unit that supplies a network synchronized clock via a cable, in a wireless sensor network, unlike a conventional method of estimating Time of Flight (TOF) using Two-Way Ranging (TWR) and Symmetric Double Sided-TWR (SDS-TWR) schemes.
