Abstract
A novel WSN location algorithm based on the frequency difference is proposed. The algorithm arbitrarily chooses two anchor nodes to send the frequency modulation signals, the distances between the unknown node and the anchor nodes can be calculated by measuring the frequency difference at the receiver, and then the localization is done using the trilateration or the maximum likelihood. The novel algorithm does not require the time synchronization and owns the strong anti-jamming capability. Meanwhile, it is applicable for both the 2-D and 3-D localization.
