Study on signal conflict of underground personnel positioning system of based on ZigBee
Chen Yan-li, Xiao Qing-lun · 2011
In order to solve the communication conflict of the mine personnel positioning system, clustering protocol is employed, in which the node receiving the strongest signal is selected as the new head of the cluster and the members are selected based on the method of RSSI similarity and neighbor node K. Simulation on clustering protocol was performed using the software MATLAB. It indicated that the speed of positioning personnel increases, the stability of the system is ensured and the consumption of power reduces based on this method.
