Experimental RSSI-based localization system using wireless sensor networks

Many ICT-based future industrial applications will require the localization of machines, devices or even workers. This work presents the experimental implementation, evaluation and optimization of an RSSI-based localization solution using IEEE 802.15.4 wireless sensor networks. The localization accuracy is analysed under different densities of deployed reference nodes. The paper also proposes a simple optimization process that helps improving the localization accuracy.
