摘要：In the WSN, information signal is mainly transmitted through sensors, aiming at the problem that DV- Hop algorithm has low accuracy in node localization, this paper propose establishing the hyperbolic two-dimensional model to determine the distance relationship of the anchor node and unknown node, and then set the error coefficient to reduce the error between the sensor nodes, finally using Stephenson iterative method (Steffensen) positioning method to locate and correct further. Simulation results show that the algorithm in the remote control has high positioning accuracy, so there is certain promotion value for it.
