The present invention discloses an anchor node energy-saving positioning and networking method based on Nash Equilibrium, which includes the following steps: step 1, establishing an anchor node space positioning plan mapping table; step 2, according to the anchor node space positioning plan mapping table, achieving anchor node networking, dividing a communication envelope and overlapping region, and determining a mobile space of the node to be positioned; step 3, based on a communication distance of the anchor node and the energy, establishing a Nash Equilibrium positioning and networking model; and step 4, achieving preferential selection of a positioning and networking strategy: on the established Nash Equilibrium positioning and networking model, sending, by the node to be positioned, a valuation signal to a candidate anchor node to determine a working state of the candidate anchor node. The present invention method achieves giving consideration to two factors of both positioning distance and the energy consumption, optimizes the positioning network during the process of anchor node positioning and networking, and reduces the energy consumption of the overall wireless positioning network node.
