Title: Study of Indoor Location Scheme Based on ZigBee Combined with Weighted Qualitative Method
Abstract: An indoor location scheme based on ZigBee wireless network technique with improved weighted qualitative algorithm was presented.The hardware requirement of this method was not very high,and the power consumption was low.The disadvantage of that the engine positioning of TI CC2431 was easy to be interfered by the environment could be remedied.Based on the principle of RSSI ranging,through analyzing the data packet,an area which connected by reference nodes near to the blind nodes was selected and the weight factor was led to figure out the coordinates of the centroid,then the coordinate of the blind nodes were obtained.The simulation test was made based on improved weighted qualitative algorithm combined with ZigBee wireless network.The results show that the location accuracy is quite high,and the system stability is good.
