Abstract: The RSSI-based localization is widely researched in wireless network, the signal strength acquirement is convenient by network nodes and need not additional hard wares. We propose a numerical method to correct and optimize the weight value from similitude signal strength named CO-WVSS for improving range accuracy. In particular, we correct and optimize a weight value to reduce errors of RSSI measurement which combined with triangle centroid localization algorithm and estimate the angel and path to optimize the localization algorithm with CO-WVSS. In addition, we perform computer simulations using the OPNET modeler in order to prove our hybrid algorithm can obviously the locating accuracy compared to the single triangle centroid localization algorithm based on RSSI.

TL;DR: Simulations of several weighted combinations of the two RSSI and AOA components in the form of pAOA + qRSSI show that increasing the number of anchors does not necessarily improve the precision and accuracy, that the AOA component is less susceptible to shadowing than the RSSI one, and that increasing their weight helps improve the accuracy and precision at high Signal-to-Noise Ratios (SNRs).
