A Weighted Centroid Localization Algorithm Based on RSSI and Virtual Static Beacon Nodes
A large number of beacon nodes will be applied to the weighted centroid localization algorithm, but too much hardware facilities will affect the efficiency of the algorithm. Using the cosine theorem, On the basis of the original beacon nodes, add some virtual static beacon nodes to participate in orientation, It can reduce the hardware cost required for positioning. In addition, the math on and analysis of the localization algorithm, by derivative principle explaining the weight coefficient and RSSI ranging influence on localization algorithm. Simulation experiments show that the weighted centroid algorithm based on VSBN needed fewer beacon nodes, high positioning accuracy.
