Wi-Fi 802.11 based mobile robotics positioning system.

摘要

This thesis provides a method for finding a location of a mobile robot based on the signal strengths obtained from the IEEE 802.11 standard wireless Access Points. In this method a set of eight signal loss functions is proposed to enable the robot to determine its current distance and direction using its known location of the Access Points. Recently a series of techniques have been proposed to address this problem, however they require a significantly larger number of data signals to determine the robot's current location. The experimental results show that the proposed approach provides better or equal accuracy of location to the existing approaches with an added advantage of the reduced computational complexity. Another advantage is that this positioning system can also be applied to the standard mobile clients using the wireless network.
