%X Aiming at the problem that the non-ranging three-dimensional distance vector based localization algorithm has a large positioning error in mountainous terrain, a wireless sensor network node localization algorithm (NLA-MT) is proposed. The algorithm effectively utilizes the characteristics of the mountainous terrain environment and uses the local plane to fit the surface of the mountainous terrain. The three-dimensional spatial positioning operation is reduced to a two-dimensional plane positioning operation to perform node positioning, which effectively improves the positioning accuracy of the node. The multi-angle simulation experiments with different communication radius, different anchor node ratios and different total nodes show that the NLA-MT localization algorithm performs well in mountainous terrain scenes. The accuracy of the non-ranging positioning algorithm of the wireless sensor network is effectively improved.
