Abstract

Wireless Sensor Network for their rapid deployment can be used in habitat monitoring for detecting fire and in disaster for helping rescue teams. Node localization is key factor for some applications. We propose the Triangular Centroid Localization algorithm (TCL). It is based in simple trigonometric figures and it does not require special hardware or synchronization time. In our simulations using the received signal strength indicator; TCL improves the accuracy of Centroid Localization (CL) in 54% and Weighted Centroid Localization (WCL) in 64%; using the link quality indicator it improves to CL in 38% and WCL in 64.98%.
