Abstract:

In order to further improve positioning accuracy of coal mine staff, equipment, articles submitted to RSSI localization algorithm combined with artificial fish-swarm algorithm using centroid algorithm based on distance of the initial population, through iterative optimization, improve positioning accuracy of a node. Simulation results show that the algorithm improves the positioning accuracy of underground network nodes.
