1. A method for determining a position of a target node using a one-way ranging technique in a wireless network, including a basic node, a first fixed node, a reference node, and a target node, comprising:

  • (a) calculating a time when an RF signal originated from the reference node is directly transmitted to the basic node and a time when the RF signal relayed from the first fixed node arrives at the basic node;

    (b) calculating a time when the RF signal originated from the target node is directly transmitted to the basic node and a time when the RF signal relayed from the first fixed node arrives at the basic node; and

    (c) determining the position of the target node based on the time calculated from steps (a) and (b).
