MDS-based algorithm for nodes localization in 3D surface sensor networks

Abstract

As Wireless Sensor Network (WSN) has become a key technology for different types of smart environment, nodes localization in WSN has arisen as a very challenging problem in the research community. Most of the applications for WSNs necessitate a priory known nodes positions. In this paper, we propose an algorithm for three dimensional (3D) nodes localization in surface WSN based on multidimensional scaling (MDS) technique. Using extensive simulations, we investigated in details our approach regarding different network topologies, various network parameters and performance issues. The results from simulations show that our algorithm produces small localization error and outperforms MDS-MAP in terms of accuracy.
