Nodes localization in 3D wireless sensor networks

Abstract

Advancement in wireless technologies brings new challenges in Wireless Sensor Network designing. One of the most important issues is nodes localization. Many different techniques have been proposed for solving this problem in two-dimensional (2D) network, but only a few consider three-dimensional localization. In this paper, we investigated an algorithm for three dimensional (3D) nodes localization in WSN based on multidimensional scaling (MDS) technique. Using extensive simulations we examined in details well known MDS-MAP technique regarding different network topologies, various network parameters and performance issues. The results from the simulations show that MDS-MAP produces acceptable localization error for 3D-WSN and can be a solid base for further improvements.
