Abstract: Aiming at the problem of large positioning error in the non-ranging 3D DV-Hop localisation algorithm for Wireless Sensor Networks (WSNs) in mountainous terrain, the NLA - MT localisation algorithm is proposed in this paper. NLA-MT utilises the characteristics of mountain terrain environment effectively. Fitting the topographic surface of the mountain with local plane, the three-dimensional spatial positioning operation can be reduced to the positioning operation of the two-dimensional plane, which improves the positioning accuracy of the node effectively. When compared with the multi-angle simulation experiments, with different communication radii, different anchor nodes and different nodes, NLA-MT performed well in the mountain terrain model, and the accuracy of the non-ranging location algorithm of the WSN is improved, with the positioning error of about 35% with a high practical value.

Keywords: WSN; wireless sensor network; mountain terrain; DV-Hop; positioning algorithm.
