A Study on the Performance of Wireless Localization System Based on AoA in WSN Environment

We introduced the localization algorithm to find the coordinates of nodes in WSN. The proposed algorithm starts at measuring the angle and distance at the landmark and their neighbors and then finding their azimuths and incident angles. In this paper, four kinds of the method to calculate and update the coordinates of nodes are proposed. The simulation results show that to utilize more data obtained from multiple paths can give more accurate position coordinates.
